A strong commercial-grade match with tighter tolerance, but lacks automotive qualification.
Best Alternatives to AC0402KRX7R9BB472
Finding a substitute for the Yageo AC0402KRX7R9BB472, an automotive-grade 4.7nF 50V MLCC, requires careful attention to its AEC-Q200 qualification. While many commercial parts match its electrical specs, they may not be suitable for high-reliability automotive applications.
AI replacement insight
Electrical riskhigh
Using a non-AEC part in an automotive design fails reliability and safety standards.
Package risklow
All candidates share the same 0402 package, ensuring physical compatibility.
Can it be replaced directly?
No direct, verified drop-in replacement has been identified. Several commercial-grade parts are physically and electrically similar but lack the critical AEC-Q200 qualification.
Best replacement path
The best replacement is another AEC-Q200 qualified 4.7nF, 50V, X7R, 0402 capacitor. If the application is commercial, CC0402JRX7R9BB472 offers a tighter tolerance.
Main risk
The primary risk is substituting a commercial-grade capacitor for an automotive-grade one, which can lead to reliability failures in harsh automotive environments.
