Lifecycle verification
Manufacturer status and the exact orderable MPN are checked before sourcing.
OBSOLETE COMPONENTS
Manage obsolete-part sourcing as a documented risk decision.
For obsolete components, the sourcing question is not only whether a part can be found. Source, condition, date code, packaging, storage history, evidence and inspection must be evaluated for the intended application.
Condition review
Packaging, labels, storage indicators and available history are evaluated.
Customer approval
Exceptions and alternative options remain subject to customer engineering approval.
WORKFLOW
Control lifecycle, evidence and substitution risk.
- 01
Verify lifecycle status
Confirm whether the exact MPN is active, NRND, EOL or obsolete.
- 02
Define acceptable supply
State date-code, packaging, condition and documentation limits.
- 03
Evaluate and inspect
Apply an agreed risk-based review to the proposed source.
- 04
Approve before order
Customer reviews the quotation, evidence scope and any deviation.
CONFIRM BEFORE ORDER
Obsolete-part controls
No alternative should be treated as drop-in without datasheet, qualification and application review by the customer.
