Are discontinued chips still worth selling?
Discontinued chips may be suitable for resale when an identifiable buyer has a requirement for the exact part and can assess the offered lot. Verify the manufacturer’s lifecycle status, preserve condition and traceability records, and separate approved service reserves from released stock. Compare written purchase or consignment terms for those released quantities. Discontinuance alone establishes neither a buyer nor a price.
A marketplace process is not proof that a buyer needs your lot. SmithTrade describes its seller process as requiring an application and credit approval, inventory details, a purchase order, testing and inspection, and payment under agreed terms. Its process supports checking transaction conditions; it does not establish demand or a resale price for your stock.
Preserve the acquisition records you actually hold. TI recommends authorized sources and explains its warranty and support limits outside those sources; labels alone do not establish authenticity. A source record or a lifecycle label does not replace lot-specific condition and authenticity review.
For EOL components, separate the manufacturer’s last-time-buy deadline from your decision about stock already owned. Establish production and service reserves, identify released quantities, and compare written purchase or consignment offers with the costs and uncertainties of holding. Decide for the actual part, lot and commitments.
Where can OEMs sell discontinued semiconductor inventory?
Compare providers by their published programme and the offer for your actual material. The examples below are research options, not a ranking, endorsement or a statement that a buyer accepts every obsolete part or every seller location.
| Documented route | What the provider publishes | Seller information / terms still to confirm |
|---|
| Smith excess programmes | Lot buys, consignment and non-consigned sales; OEM/EMS matching is described. | Lot eligibility, price, payment dates and charges require an offer. Its SmithTrade page requires MPN, manufacturer and quantity and describes seller approval and inspection. |
| Hybrid Electronics | Publishes outright purchase and consignment for OEMs, EMS providers and contract manufacturers, including obsolete/EOL stock. | Send a spreadsheet with identified parts, quantity and available date/condition information. Confirm the particular lot, accepted country, inspection and payment terms. |
| ZDI | Describes outright excess-stock purchase, consignment and manufacturer/OEM remarketing. | Offers stock-file submission or purchasing-desk contact. The reviewed page does not settle the seller-country rules, payment schedule or unsold-stock obligations for a proposal. |
| Fusion Worldwide | Describes outright purchase and consignment/revenue share after review and inspection. | MPN, manufacturer and quantity are required. Confirm row eligibility, deductions, settlement dates and remaining-stock terms in the actual agreement. |
| AERI | Publishes whole/partial liquidation purchase, line-item bids and consignment. | Requests inventory evaluation; a contract defines the consignment share. Payment dates, accepted locations and unsold-stock treatment need confirmation. |
OEM submission checklist
- Identify the legal owner, release authority, customer restrictions and quantities retained for builds, service or warranty.
- Use one row per full manufacturer part number and distinguish manufacturer, quantity/unit, date and lot codes, packaging and actual condition.
- State stock country/location, available traceability records and any missing information. Keep unopened, opened, partial and loose packs identifiable.
- Request the arrangement you want: outright sale, consignment, or separate proposals. Confirm inspection, title transfer, accepted rows, payment, shipping and unsold-stock terms before transfer.
ICULTRA can first assess lists from OEMs, CEM/EMS businesses and distributors across the Americas, Europe and Asia. Mixed lots, loose ICs and opened or partial reels may be submitted for assessment; whether to purchase and at what price is decided per lot. A buyback enquiry is not an unconditional purchase commitment or a supplier-return authorisation. Send the identified released list through the email or WhatsApp links on this page.
For detailed purchasing-model comparisons, use the surplus inventory buyer comparison. For seller eligibility, see the U.S. OEM buyer comparison. For an internal cancellation, follow the cancelled-project liquidation workflow.
Provider pages reviewed 5 November 2026. An undisclosed term is a question to resolve, not evidence that a service is unavailable.
How much warranty stock should we retain before selling retired product-line components?
Before selling retired product-line components, define the remaining warranty and service commitments, forecast part-level demand from the supported installed base and failure history, and document uncertainty and replenishment options. Have service, engineering, finance and the release owner approve a reserve. Offer only the usable, owned quantity left after that reserve and other commitments; no fixed retention percentage suits every programme.
Start with obligations for the actual programme and jurisdiction. The FTC’s business warranty guide addresses US consumer-product warranty law; it does not establish a worldwide retention period or a rule for every B2B component sale. Have the responsible contract or legal owner identify the commitments that apply.
Oracle’s service-parts planning documentation explains forecasts using service consumption, supported product population and failure data, including retirements. These are planning inputs, not a mandated reserve. Behfard and colleagues’ 2013 working paper on last-time buys and repair studies uncertainty and repair alternatives for capital-goods spare parts; its model is not a universal percentage for semiconductor stock.
Blank retention worksheet
Download the blank warranty-stock retention worksheet (CSV). Enter one part/programme per row, use consistent units and nonnegative quantities, and record source/revision fields. Reconcile other commitments against usable stock rather than allowing an overallocated list. The file contains no customer data, assumed failure rates or preset reserve percentages. Empty inputs mean unknown; do not treat them as zero or release stock until reviewed.
| Worksheet field | What to record |
|---|
| Programme, full MPN and unit | Record the supported product, exact ordering code, BOM revision and counting unit. |
| Installed base and support horizon | Record supported units, planned retirements, start/end dates and the evidence for remaining commitments. |
| Failure/consumption history and demand estimate D | Use a stated period and compatible unit. Document gaps, forecast method and remaining-period demand. |
| Uncertainty allowance U | Record an approved quantity and rationale; leave blank if the uncertainty has not been resolved. |
| Approved alternative supply A | Count only documented, usable and reliable quantities available before the corresponding service demand, with quantity and timing evidenced. Do not offset demand that falls before the supply arrives. Unresolved delivery timing means no approved release for the affected rows. |
| Usable owned on-hand S and other commitments C | Reconcile physical quantity and condition. Exclude quarantine or disputed ownership from S; record other approved allocations in C. |
| Service reserve target R | Ceiling of max(0, D + U − A). This planning worksheet is a documented assumption, not a universal service-level optimisation. |
| Retained on-hand / proposed release | Retained on-hand = min(max(0, S − C), R). Proposed release = max(0, S − C − R). Flag a shortage when S − C is below R. |
| Approvals and next review | Record the responsible roles, actual approver names, date, reserve/list revision and the next review or event. Blank approval means no approved release. |
Estimate D for the remaining support period from the available installed-base and service records. Review uncertainty, replenishment lead time, actual lot condition and approved repair or substitute options with engineering and service. Rochester Electronics describes authorized stored stock and licensed manufacturing as possible ways to extend supply. Confirm availability and timing for the exact part in writing before counting either route toward your reserve. The worksheet arithmetic is a transparent starting point: critical service levels or uncertain failures may require a fuller inventory model. It does not approve a substitution or guarantee future supply.
Release approvals and reassessment triggers
- Service/warranty owner: confirms supported population, commitment end dates and expected demand.
- Engineering/quality owner: reviews part suitability, usable condition and any repair or alternative-supply assumptions.
- Finance owner: reviews the reserve rationale and commercial impact; does not substitute book value for demand.
- Inventory/release owner: reconciles owned physical stock, approved quantities and the exact sale-list revision. Record actual names and approval dates.
- Reassess when failures or consumption depart from assumptions; support commitments or the installed base change; a supplier notice or lead time changes; a replenishment source fails; lot condition or usable quantities change; or the scheduled review date arrives.
Keep the approved retained quantity separate from the released inventory list. ICULTRA assesses the released material; it does not determine your warranty obligation or approve a reserve for your programme.
Planning references reviewed 5 November 2026. The CSV is a blank planning aid requiring the seller’s own review and approval.
Start with the exact manufacturer notice
Check the affected ordering code, package and grade against the actual product discontinuance notice. Record the last-order and last-shipment dates separately. A family-level lifecycle label does not establish the deadline or the availability of a particular lot.
TI distinguishes active, not recommended for new designs, last-time-buy and obsolete products. These are manufacturer production statuses, not quotations or evidence of another seller’s stock. Analog Devices describes separate last-time-buy and last-time-ship periods; use the affected model’s notice rather than applying another manufacturer’s general timetable.
Separate required stock from stock released for sale
Prepare a part-level review with production, service and warranty requirements identified separately. Record the approved demand horizon, quantities already owned, usable stock, outstanding commitments and unresolved engineering decisions. A slow-moving line can still have a service obligation; lack of recent consumption alone does not establish that it is surplus.
Have the responsible teams approve retained and released quantities. A simple years-times-usage calculation can be a discussion input, but it does not establish the correct reserve when failure rates, commitments or programme plans are uncertain. See the cancelled-programme inventory review for the related release decision.
Compare the routes on a documented basis
| Route | Question to resolve | Evidence to record |
|---|
| Last-time buy | Is additional supply needed for an approved requirement? | Affected code, notice dates, demand assumptions, usable stock and purchase terms. |
| Hold for production or service | Which obligations justify the reserve? | Approved quantities, storage requirements, review owner and next review date. |
| Outright sale | Does the written offer meet the seller’s objectives? | Accepted rows, inspection conditions, price, payment trigger and delivery terms. |
| Consignment | Are the resale arrangement and remaining-stock obligations acceptable? | Authority, custody, reporting, charges, settlement and withdrawal or return terms. |
| Internal reuse or recovery | Can the material be used appropriately, or does it need a different disposition route? | Engineering approval where relevant, receiving-party suitability and requirements for the actual material and jurisdiction. |
There is no route that is automatically preferable for every EOL lot. A last-time buy acquires additional material; selling concerns stock the business already owns and can release. Those decisions can coexist for different parts or quantities. An available offer does not by itself justify releasing a service reserve.
Preserve storage and condition evidence
Record readable date and lot codes, original or changed packaging, moisture-sensitive handling information and the storage records actually available. Keep opened, sealed and partial packs identifiable. Do not infer condition, authenticity or a fixed price reduction from a date label alone.
TI’s product shelf-life guidance discusses packaging, moisture sensitivity and customer storage conditions. It does not certify a seller’s particular lot or establish a resale-price formula. Apply the relevant manufacturer’s instructions and agree any inspection scope for the offered material.
Compare an actual offer with the holding decision
Use the same released list revision for each quotation. Identify included and excluded rows, quantity basis, condition assumptions, inspection adjustments, currency, validity period, payment timing and collection responsibilities. Record known holding costs and unresolved demand assumptions separately; do not substitute a historical industry-inventory total for a lot valuation.
If finance needs funds by a particular date, ask whether the actual offer and settlement conditions can meet it. Neither the term “outright purchase” nor a consignment listing guarantees payment by month-end. Use the valuation and quotation-comparison guide to identify differences between offers.
Prepare the ICULTRA enquiry
ICULTRA is the excess inventory buyback brand of SENICO ELECTRONICS INTL CO., LIMITED. It offers outright purchase and consignment for individual-lot assessment. Send manufacturer, full MPN, quantity, packaging, date codes where available, actual condition, location and available records. Identify held or excluded quantities and state which arrangement you want to discuss.
Initial buyback assessment is free and without obligation. Confirm eligibility, inspection, pricing, payment, shipping, additional authorised work and any unsold-stock arrangements in writing. Mixed lots, loose ICs, opened packaging and partial reels can first be submitted for assessment; purchase and price are confirmed per lot. See the complete seller’s guide for the submission and contract checklist.
Keep the decision reviewable
Save the manufacturer notice, approved reserve and released-list revision, supporting records, offers, decision owner and next review date. Revisit the decision when demand, commitments, condition evidence, manufacturer notices or offer terms change. A calendar review does not require selling, buying or changing a page’s publication date.
Where reuse or resale is unsuitable, identify the actual material and receiving party before arranging recovery. Applicable requirements depend on jurisdiction and material classification. A global whole-product e-waste statistic does not determine the legal treatment of every unused semiconductor lot.
