Is there a pin-compatible replacement for AC0402FR-071RL?

While several candidates share the 0402 package, none are a true pin-compatible replacement due to differences in tolerance, TCR, or the critical AEC-Q200 qualification.

What risks should I check before replacing AC0402FR-071RL?

The main risks are: 1) Using a non-AEC-Q200 part in an automotive design. 2) Accepting a wider resistance tolerance (e.g., ±5% vs ±1%). 3) Using a part with a higher TCR, which affects performance over temperature.

AI replacement insight

Electrical riskhigh

Candidates may have wider tolerance or higher TCR, affecting circuit precision.

Package risklow

All viable candidates share the same 0402 package.

Sourcing riskhigh

Replacing an automotive-grade part with a commercial one can lead to qualification and reliability issues.

Can it be replaced directly?

No, a direct drop-in replacement for AC0402FR-071RL has not been found. All candidates lack the AEC-Q200 qualification and/or have weaker electrical parameters.

Best replacement path

For non-automotive use, FH RC-02U1R00FT is the closest match, but has a higher TCR. For automotive applications, a direct replacement has not been identified.

Main risk

The primary risk is substituting a general-purpose resistor for an automotive-grade (AEC-Q200) component, which could compromise system reliability and safety.

Recommended alternatives

Parametrically similar but has a higher TCR and is not automotive grade.
