Is there a pin-compatible replacement for PA1206FRF470R03L?

RLS12FTCR030 shares the same 1206 package and pinout. However, it is not a direct drop-in replacement due to a lower maximum operating temperature and lack of automotive (AEC-Q200) qualification, which must be validated.

What risks should I check before replacing PA1206FRF470R03L?

Key risks to check are: 1) Thermal performance, as substitutes may have a lower max temperature. 2) Automotive compliance, as the target is AEC-Q200 qualified. 3) For parametric alternatives, ensure any resistance value difference is acceptable.

PA1206FRF470R03L Alternatives, Datasheet & Cross Reference | Yageo

PA1206FRF470R03L is an automotive-grade 1W, 30mΩ current sense resistor. While alternatives in the same 1206 package exist, they require careful review of key differences in temperature rating and AEC-Q200 qualification.

AI replacement insight

Electrical riskhigh

Qualification and temperature rating differences are critical. Parametric differences in resistance exist for some options.

Package risklow

All viable candidates share the same 1206 package.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates require review for lower temperature ratings and lack of AEC-Q200 qualification.

Best replacement path

RLS12FTCR030 offers the closest parametric match but requires downgrading from automotive-grade specs.

Main risk

The primary risk is substituting a non-automotive grade part with a lower temperature rating into a system designed for the AEC-Q200 target.

Recommended alternatives

A 1206 resistor with matching specs but lower temp rating and no AEC-Q200 qualification.
