Needs validationhigh risk
Cross-vendor thin-film part with very close resistance and better precision, but no automotive rating.
Best Alternatives to AC0402DR-07255KL
Yageo's AC0402DR-07255KL is an automotive-grade 255kΩ 0.5% resistor in a 0402 package. Finding a direct replacement requires matching its AEC-Q200 qualification, package, and key electrical parameters.
AI replacement insight
Application riskhigh
Substituting a non-AEC-Q200 part into an automotive design is a major reliability risk.
Electrical riskmedium
Candidates have different tolerance, technology, or resistance values that require circuit validation.
Package risklow
All candidates share the same 0402 package, ensuring physical compatibility.
Can it be replaced directly?
No direct, fully-equivalent replacement has been identified. All candidates have parametric differences or lack the target's AEC-Q200 automotive qualification.
Best replacement path
For non-automotive use, RC0402FR-07280KL is a close match if ±1% tolerance is acceptable. For higher precision, ARG02BTC2493 is a strong candidate.
Main risk
The primary risk is using a non-automotive grade component in an application that requires AEC-Q200 reliability standards.

Questions & answers
The best alternative depends on your application's tolerance for changes. For similar technology, RC0402FR-07280KL is a thick-film option but has wider tolerance (1%). For higher precision, ARG02BTC2493 is a thin-film option with tighter tolerance (0.1%). All require verifying the lack of AEC-Q200 rating.
