Is there a pin-compatible replacement for AC0402FR-0744K2L?

FRC0402F4422TS is physically and electrically similar (form, fit, and function) but is not a direct pin-to-pin replacement for its intended automotive use because it lacks AEC-Q200 qualification.

What risks should I check before replacing AC0402FR-0744K2L?

The main risk is reliability; the target is AEC-Q200 qualified for automotive use, and substitutes may not be. Also check for differences in resistance value, technology (Thick vs. Thin Film), and temperature coefficient (TCR).

AC0402FR-0744K2L Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo AC0402FR-0744K2L, a 44.2kΩ 1% AEC-Q200 resistor, requires careful review. While functional matches exist, the automotive qualification is a key differentiator that must be matched for equivalent reliability.

AI replacement insight

Application riskhigh

Using a non-AEC-Q200 part in an automotive design is a major compliance and reliability risk.

Package risklow

All viable candidates share the same 0402 package, ensuring physical compatibility.

Can it be replaced directly?

No direct, verified pin-to-pin replacement has been identified. All candidates require review, primarily for the missing AEC-Q200 qualification.

Best replacement path

The best path is another AEC-Q200 qualified, 44.2kΩ, 1%, 0402 thick film resistor. For non-automotive use, FOJAN FRC0402F4422TS is a strong functional match but carries risk.

Main risk

The primary risk is using a non-automotive grade component in an application that specifies AEC-Q200, potentially affecting long-term reliability and safety.

Recommended alternatives

A functional match in a 0402 package with the same resistance and tolerance, but not automotive grade.
