Needs validationlow risk
A pin-compatible alternative with matching key electrical parameters, but lacks specified AEC-Q200 qualification.
Best Alternatives to RLP25FEGR075
The TAI-TECH RLP25FEGR075 is a 3W, 75mΩ AEC-Q200 current sense resistor. While a pin-compatible alternative with matching electricals exists, it requires review for automotive qualification. Several parametric alternatives with slightly different resistance values are also available.
AI replacement insight
Electrical riskmedium
Using parametric alternatives with different resistance (e.g., 80mΩ) will alter circuit behavior and requires redesign or validation.
Application riskmedium
The pin-compatible option lacks specified AEC-Q200 qualification, making it a risk for automotive designs without further verification.
Package risklow
All viable candidates use the same 2512 package, ensuring form-fit compatibility.
Can it be replaced directly?
Direct replacement for RLP25FEGR075 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
HoYLR2512-3W-75mR-1% is the best path for a direct replacement, provided the lack of specified AEC-Q200 qualification is acceptable. If not, no direct replacement was found.
Main risk
The primary risk is either a mismatch in automotive qualification (AEC-Q200) or a change in resistance value if using a parametric alternative.
