Check That a Component Certificate Applies to the Received Shipment

A certificate stored beside an incoming shipment may describe the right supplier but the wrong product, order, or lot. Before accepting it as receiving evidence, establish what the document actually covers. A recognizable logo and a familiar part description are insufficient to make that connection.

DigiKey’s quality and traceability information describes certificates of conformity and traceability identifiers. The practical review should use the actual document and purchase requirements; different certificate types provide different statements and levels of shipment detail.

Identify the document’s scope

Record the issuer, document identifier, issue date, referenced order or shipment, and stated product identity. Read the declaration itself rather than relying on its filename. Check whether attached schedules or referenced pages are present before deciding that the document is complete. A supplier’s quality-system certificate and a statement about a particular delivered product answer different questions.

Compare the full manufacturer part number, including relevant orderable suffixes, with the received material. Where the certificate uses a distributor or customer item code, find the controlled mapping to the manufacturer identity. Avoid matching solely on a shortened description such as “microcontroller” or “connector.”

Build the shipment linkage

Where multiple lots are delivered under one line, determine whether the certificate identifies them individually or covers the shipment through another explicit reference. An absent lot field is not automatically a defect in every certificate, but the evidence must satisfy the traceability requirement that the order actually established.

Resolve discrepancies without inventing data

1. Preserve the received document unchanged.
2. Record the exact field that fails to match.
3. Ask the issuer for clarification or a corrected document.
4. Keep affected material identifiable while the issue is resolved.
5. Attach the final evidence to the receiving record.

Do not edit a supplier certificate internally to make a part number or quantity agree. Add a separate explanation or obtain a corrected issue from the responsible source. Preserve the relationship between the original and replacement documents so that the reason for correction remains visible.

This check establishes documentary applicability. It does not independently prove every electrical characteristic or eliminate the need for inspection required by the product’s receiving plan. State the conclusion narrowly: the document supports the identified shipment within its written scope, and any remaining verification requirements retain their own evidence.
