A close parametric match in a 0402 package, but is not automotive grade.
Finding a substitute for the Yageo AC0402FR-078K2L, an 8.2 kΩ 1% 1/16W 0402 resistor, requires careful attention to its AEC-Q200 automotive qualification. While many parts match electrically, few meet this critical reliability standard.
Substituting a commercial part for an automotive one can violate design and safety requirements.
Some candidates have different resistance values or technology (thin film) that require circuit analysis.
All candidates match the 0402 package, ensuring physical compatibility.
No direct, AEC-Q200 qualified replacements were found among the candidates. All proposed alternatives are commercial grade and present a risk in automotive applications.
Use a commercial-grade part like FRC0402F8201TS for non-automotive applications after verification. For automotive use, source an AEC-Q200 qualified part.
The primary risk is using a non-automotive qualified component in a system requiring AEC-Q200 reliability, which can lead to premature failure.
