Matches resistance, power, and package, but has a weaker TCR and lacks AEC-Q200 qualification. Engineering review is required.
VMS-R330-1.0-U is a 3W, 330mΩ, 1% precision current sense resistor from Isabellenhuette in a 2512 package. It features a very low TCR (<20 ppm/K) and is AEC-Q200 qualified for demanding applications.
TCR mismatch can affect precision in sensitive applications.
All viable candidates use the same 2512 package.
Alternatives are available from different manufacturers.
Direct replacement for VMS-R330-1.0-U should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The closest match is HoJLR2512-3W-330mR-1%, but it's a performance downgrade in terms of thermal stability (TCR) and lacks an automotive qualification.
The primary risk is a change in circuit accuracy over temperature due to the substitute's higher TCR.
