Reducing counterfeit-component risk starts with the purchasing route and supporting records. Establish the manufacturer's authorized channels, identify the exact part and define the evidence required before buying. Inspection can help detect discrepancies, but it should not be presented as a universal authenticity guarantee.
Verify the source through the manufacturer
TI's authorized-distributor guidance explains the risks associated with purchases outside its authorized network. Analog Devices maintains an official authorized-distributor directory. Consult current manufacturer resources rather than relying only on a seller's logo collection or an old authorization document.
Confirm the legal seller, the offered manufacturer's full order code and the claimed origin of the material. If purchasing outside an authorized route, make that distinction explicit and have the responsible quality team review the available evidence and acceptance policy. Do not describe an independent quotation as manufacturer-authorized without verification.
Define evidence before accepting an offer
Request the records relevant to the purchase: origin information, lot and date-code details, packaging condition and agreed warranty or return terms. Check that the offered material matches the approved package, grade and suffix. A general certificate with no connection to the supplied lot provides limited purchasing evidence.
Ask how split quantities or repacked material retain identification. Record inconsistencies between the quote, label and shipping documents before releasing the order. If essential evidence is unavailable, document the gap instead of replacing it with an assumption based on price or apparent scarcity.
Inspect and disposition received material
Reconcile quantities and identifiers against the purchase record. Examine packaging and labels under the agreed receiving procedure, and route unexplained differences for review. Keep material with unresolved discrepancies separate from accepted production stock.
Where additional testing is required, define its scope, sampling method and limitations with qualified personnel. Electrical tests can assess sampled behavior, while other methods investigate different risks. Passing one check does not prove the origin or condition of every unit. Preserve reports and the final acceptance decision with the lot record.
Frequently asked questions
Do sealed packaging and clear markings prove authenticity?
No. They are observations that must be considered with source records and other evidence. They should not replace verification of the purchasing route and lot history.
What if the only offer is from an independent supplier?
Apply your organization's approved risk-review and acceptance process. Request available origin records and agreed inspection terms, then obtain a documented decision from the responsible team before production use.
Send SENICO your exact part requirement and required evidence list. Stock, price, lead time and the availability of requested documentation require quotation confirmation.
