Quick answer: Only after it meets the approved material, functional, interface and validation requirements applicable to the product.
Can a dimensionally similar alternate supplier part be accepted directly?
A matching drawing is a starting point, not complete equivalence evidence. Preserve supplier and sample identity, compare test methods and review process differences. Qualification should address the actual product risks without assuming all suppliers use the same route.
A practical verification method
Compare identified alternate samples against the same requirements and document any permitted differences.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Compare identified alternate samples against the same requirements and document any permitted differences. | Resolve the specific question before approval |
Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
