Upgrade with higher 3W power rating and superior TCR (<20ppm/K), in the same 2512 package.
Finding a substitute for the Yageo PE2512FKE7W0R05L 2W, 50mΩ current sense resistor involves matching the 2512 package, resistance, and AEC-Q200 qualification. Key considerations are power rating and TCR.
TCR mismatch can affect circuit accuracy over temperature.
All viable candidates use the same 2512 package.
Some candidates lack explicit AEC-Q200 qualification, limiting use in automotive designs.
Direct replacement for PE2512FKE7W0R05L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
VMS-R050-1.0-U offers an upgrade with a 3W power rating and a much better TCR, while also being AEC-Q200 qualified.
The main risks are ensuring the replacement has an equal or better power rating (≥3W recommended) and a suitable TCR for the application's precision requirements.
