Form-fit match with identical electricals but lacks automotive qualification.
AC0402KRX7R9BB682 is a 6.8nF, 50V, X7R automotive-grade (AEC-Q200) ceramic capacitor in a 0402 package. Alternatives must be carefully reviewed for application requirements, especially automotive qualification.
Using a non-AEC-Q200 part in an automotive design can lead to premature failure and safety issues.
Candidates share the same 0402 package, ensuring physical compatibility.
No direct drop-in replacement matching all specs, including AEC-Q200, has been identified. Functional alternatives exist for general-purpose use.
For non-automotive use, TCC0402X7R682K500AT is a strong candidate. For automotive, an alternative AEC-Q200 part must be sourced.
The primary risk is substituting a non-automotive grade capacitor into an application requiring AEC-Q200 reliability.

Form-fit match with identical electricals but lacks automotive qualification.
