A long-running product still needs a component that is no longer easy to buy. Redesigning the board may be possible, but it takes engineering time. Buying remaining stock may help, provided the offered material meets the project’s requirements.

WOMAiELEC accepts sourcing enquiries for obsolete components and requests to review possible alternatives. Before comparing offers, decide what your project can actually accept.

Confirm the lifecycle information

Check the manufacturer’s information for the complete ordering code. A part missing from one distributor’s catalog does not, by itself, establish that the manufacturer has discontinued it. Where available, review the relevant product discontinuance notice and its dates.

Keep the notice or reference with the enquiry. Avoid treating a whole product family as discontinued when the information applies to a particular ordering code.

Decide whether you need the original part only

If the approved BOM permits no substitution, state “original manufacturer and exact ordering code required.” Ask that any deviation be identified separately. A different package or suffix should not quietly enter the quote as an equivalent.

If engineering can review alternatives, provide the original part and the constraints that matter in the actual design. Depending on the device, these may include package, pinout, operating conditions, timing and software. Your engineering team must approve the replacement; a similar description or a supply offer is not validation.

Set quantity around the project requirement

Separate the immediate production requirement from repair stock or future builds. Ask your team to identify the quantities and dates it can support, rather than placing a large order simply because a part is described as scarce.

If you plan a larger purchase, include storage and later assembly requirements in the review. The suitability of older material depends on the device, packaging, handling history and application. A date code alone does not settle that assessment.

Ask about the actual material being offered

Request available packaging details, label information, lot and date-code information, and supply documents. Establish which records are available for the offered material and what remains unverified.

Where inspection is required, agree on the scope and acceptance criteria before ordering. A document should be reviewed for what it establishes and which material it covers. A photograph alone cannot prove authenticity or electrical performance.

Keep the engineering and purchasing decisions connected

Before accepting an offer, compare its full ordering code, quantity, packaging, documentation and delivery conditions with the approved requirement. Have engineering review any technical deviation and make the decision visible in the order record.

How to send an obsolete-part enquiry to WOMAiELEC

Include the manufacturer, complete ordering code, required quantity, destination and required date. Add any manufacturer lifecycle notice, packaging requirements and required documents. Tell us whether alternatives are excluded, already approved or open for engineering review.

We can review the sourcing request and clarify the supply conditions for quotation. Final availability, inspection scope, documents and delivery terms require confirmation for the specific material and order.
