Best Alternatives to RLP25FEGR100
RLP25FEGR100 is a 3W, 100mΩ, 1% tolerance AEC-Q200 current sense resistor in a 2512 package. Several pin-compatible alternatives exist, offering similar or improved performance for automotive and industrial applications.
AI replacement insight
Electrical riskhigh
Using a part without matching AEC-Q200 qualification in a required application can lead to premature failure.
Package risklow
Multiple candidates share the same 2512 package, but land pattern should always be verified.
Can it be replaced directly?
Direct replacement for RLP25FEGR100 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Upgrade to VMS-R100-1.0-U for higher power handling and precision, or use LR123WF400NT4E for a like-for-like replacement.
Main risk
The main risk is using a substitute without AEC-Q200 qualification in an automotive or high-reliability application that requires it.
