Yageo
Needs validationmedium risk
A functional alternative with better tolerance and TCR, but lacks automotive qualification.
Best Alternatives to AC0402FR-0724KL
AC0402FR-0724KL is a 24kΩ 1% AEC-Q200 resistor. While pin-compatible parts exist, finding a substitute with equivalent automotive qualification is critical.
AI replacement insight
Electrical riskhigh
Using a non-qualified part or one with different tolerance/TCR can affect circuit performance and reliability.
Package risklow
The 0402 package is standardized, ensuring physical compatibility.
Can it be replaced directly?
No direct, fully qualified drop-in replacement has been identified. All candidates require review, primarily for the lack of AEC-Q200 qualification.
Best replacement path
Source another AEC-Q200 qualified resistor with identical parameters, such as from Yageo's AC series or a competitor's automotive line.
Main risk
Loss of AEC-Q200 automotive qualification, which can compromise reliability and safety in automotive environments.
