AI replacement insight
Application riskhigh
Using a non-AEC-Q200 part in an automotive design is a high risk.
Electrical risklow
If AEC-Q200 is matched, electrical risks are low as several options exist.
Package risklow
The 0402 package is standard and widely available.
Can it be replaced directly?
Yes, Yageo AF0402FR-071KL is a potential pin-to-pin replacement. It matches the 1kΩ, 1%, 1/16W, 0402 specs and is also AEC-Q200 qualified.
Best replacement path
Yageo's AF0402FR-071KL is the strongest candidate, matching all key parameters including AEC-Q200 qualification, and offering an improved TCR.
Main risk
The primary risk is substituting with a non-automotive grade part, as the target is AEC-Q200 qualified. This could lead to reliability issues in harsh environments.
