How Part Number Supersession and Cross-Reference Numbers Work
Supersession and cross-reference numbers can help sourcing, but they still need application checks before ordering.
A supersession number usually means a part reference has been replaced by a newer reference in a catalog or supply chain. A cross-reference number connects similar or related part references from another supplier or catalog.
These references are useful for sourcing, but they should not replace checking the old part, machine details, serial number, and visible dimensions. International buyers should send every number found on the part or package.

Reference Table
| Supersession | A newer reference may replace an older one in a catalog or supplier system. |
|---|---|
| Cross-reference | A related reference may help compare supplier catalogs but still needs review. |
| Application check | Visible part details and machine information remain important. |
