EOL & OBSOLETE SOURCING

Keep legacy production moving when critical parts disappear.

Source end-of-life, obsolete, NRND and allocation-constrained electronic components through our Shenzhen market access and supplier network. Every request is reviewed against the exact part number, quantity and commercial requirements.

Submit an EOL request How sourcing works

Supplier availability, pricing, MOQ, date code, packaging and lead time are confirmed for each quotation.

DEEP SOURCING, CONTROLLED REVIEW

A sourcing path for parts standard catalogs no longer solve.

Chip-seek combines direct access to Shenzhen's deep electronics market with a structured RFQ process. We use the requirement itself as the starting point, then confirm supplier, commercial and quality details for the specific offer.

01

Exact part-number search

We review the requested manufacturer part number, known suffixes and package details before supplier matching.

02

Lifecycle and manufacturer review

Lifecycle status, manufacturer information and available notice details are considered alongside the commercial request.

03

Package, date-code and quantity alignment

Packaging, date-code expectations, required quantity and delivery timing are captured before an offer is presented.

04

Alternatives without hidden assumptions

Potential substitutes are separated from exact matches so engineering teams can review form, fit and function independently.

FROM REQUIREMENT TO QUOTATION

One structured path, with human review at the critical points.

Hard-to-find sourcing moves quickly, but the decision trail should stay clear. Each request passes through the same four-stage review.

01

Submit the exact requirement

Share manufacturer part numbers, quantities, target timing and any package, date-code or documentation requirements.

02

Build the supplier match

Our sourcing team reviews the requirement across relevant supplier channels and identifies exact-match or alternative paths.

03

Confirm offer details

Availability, MOQ, price, lead time, packaging, date code and quality scope are checked for the proposed source.

04

Deliver a structured quotation

You receive a clear offer for procurement review, with exceptions and open questions identified before ordering.

No offer is treated as confirmed until its commercial and quality details have been reviewed for the requested quantity.

A BETTER RFQ BRIEF

Better inputs produce faster, safer sourcing decisions.

A complete requirement helps the sourcing team eliminate mismatches early and gives procurement a quotation that is easier to compare and approve.

What to send

Part number and manufacturer

Exact MPN, preferred manufacturer and known suffix or package.

Quantity

Required quantity, acceptable split shipments and future demand.

Timing

Required delivery date and whether the request is line-down critical.

Acceptance criteria

Packaging, date code, traceability, inspection or documentation needs.

What you receive

Match status

Exact match, candidate alternative or further information required.

Commercial detail

Quoted quantity, unit price, MOQ, lead time and offer validity.

Quality scope

Available supplier, packaging, date-code and documentation details.

Risk and alternatives

Known exceptions, unresolved questions and optional substitute paths.

Important sourcing boundary

Chip-seek reviews warehouse-held legacy inventory together with qualified sourcing channels. Availability and offer conditions are confirmed for the specific quotation.

QUALITY SCOPE

Quality expectations belong in the request, not after the quote.

EOL sourcing can involve multiple supply channels. Tell us the inspection, traceability and acceptance requirements that matter to your organization, and we will confirm what is available for the proposed source. No certification or documentation is assumed unless it is stated in the quotation.

PKG

Package alignment

Requested package, packing method and quantity format are reviewed against the proposed offer.

LOT

Date-code visibility

Available date-code or lot information is stated where the supplier can support it.

DOC

Documentation scope

Requested traceability, inspection or supporting documentation is confirmed as part of the offer.

RISK

Exception visibility

Material exceptions and unconfirmed requirements are identified before a procurement decision.

LEGACY SOURCE REVIEW

Obsolete sourcing needs more than a part-number match.

Older material can move through different supply paths. Keep identity, packaging, evidence and exceptions visible before a purchasing decision.
