A pin-compatible alternative with higher power and better TCR. AEC-Q200 qualification needs verification.
YAGEO's PA2512FKE7W0R003E is a 2W, 3mΩ AEC-Q200 qualified current sense resistor in a 2512 package. This page reviews several potential alternatives, highlighting key parametric differences for engineering evaluation.
Key parameters are matched or improved, but thermal aspects need review.
All viable candidates match the 2512 package.
Alternatives are from different manufacturers, requiring new vendor qualification.
Direct replacement for PA2512FKE7W0R003E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
HoLLR2512-3W-3mR-1% is a strong upgrade if AEC-Q200 is not required or can be verified. LR123WF300NT4E is also strong but requires checking the thermal environment.
The main risks are mismatched thermal characteristics (TCR, operating temp) and missing automotive qualifications (AEC-Q200).
