Yageo
A parametrically similar commercial-grade capacitor with tighter tolerance, but lacks automotive qualification.
AC0805KRX7R9BB102 is an AEC-Q200 qualified 1nF 50V 0805 MLCC from Yageo. Finding a direct, qualified replacement is critical for automotive applications, as commercial-grade parts may not meet reliability standards.
The 0805 package is standard and widely available.
Sourcing a part with the correct AEC-Q200 qualification is critical and may be more difficult than finding a commercial part.
No direct, fully-qualified replacement has been identified. All reviewed options lack the required AEC-Q200 automotive rating, making them high-risk.
Search for an alternative 1nF, 50V (or higher), 0805 MLCC that is explicitly AEC-Q200 qualified from a reputable manufacturer.
Substituting a non-AEC-Q200 qualified capacitor in an automotive application can lead to component failure and system malfunction.
