AI replacement insight

Application riskhigh

Using a non-AEC part in an automotive design is a high risk.

Electrical risklow

Electrical parameters for top candidates are well-matched or improved.

Package risklow

All viable candidates use the same 2512 package.

Can it be replaced directly?

Yes, RLP25FEGR030 is a potential drop-in upgrade. However, non-automotive grade parts exist but require careful validation as they lack AEC-Q200 qualification.

Best replacement path

RLP25FEGR030 from TAI-TECH is a strong upgrade, offering higher power (3W) and better TCR (±50ppm/°C) while maintaining AEC-Q200 qualification.

Main risk

The main risk is using a non-AEC-Q200 qualified resistor in an automotive application, which can compromise long-term reliability and safety.
