Why one part can have several numbers
A part may receive different numbers after a manufacturer revision, a supplier change, a regional catalog update, or an aftermarket catalog mapping. Formatting differences can also create apparent variants.
- Superseded OE numbers
- Supplier references
- Regional catalog references
- Numbers with different spacing or punctuation
What must still be verified
Two references can point to the same vehicle family while differing by engine, production break, transmission, climate package, or connection layout. The vehicle and physical part should therefore remain part of the decision.
- Application and production period
- Core dimensions
- Tank or manifold arrangement
- Pipe and mounting positions
- Included fittings or sensors
A safer purchasing record
Keep the searched number, the matched number, the supporting catalog source, and the final confirmed application together. This makes later quotation, sampling, and quality follow-up more traceable.
