Yageo
Shares the same package and voltage, with tighter tolerance, but has a significantly different capacitance.
Finding a substitute for the Yageo CC1206KKX7R9BB684, a 0.68µF 50V 1206 MLCC, requires careful parametric review. While form-fit compatible parts exist, no direct electrical matches were found, necessitating engineering validation for any alternative.
Capacitance values differ by over 30%, which can cause circuit malfunction.
All kept candidates use the same 1206 package, ensuring physical fit.
The proposed alternatives are active parts from major manufacturers, but the original part's availability should be checked first.
No, there are no direct, drop-in replacements for CC1206KKX7R9BB684 among the candidates reviewed. All alternatives have a different capacitance value.
No direct drop-in replacements were found due to capacitance differences. The best path is to search for a 0.68µF, 50V (or higher), X7R capacitor in a 1206 package. If unavailable, evaluate candidates with 1µF capacitance for non-critical bulk decoupling applications after engineering review.
The primary risk is the significant capacitance mismatch, which can alter circuit performance, especially in timing, filtering, or resonant applications.
