Needs validationhigh risk
Functionally similar with higher voltage (50V), but in a larger 1206 package.
Best Alternatives to CC0805KKX7R8BB684
CC0805KKX7R8BB684 is a general-purpose 0.68µF, 25V, X7R MLCC in a standard 0805 package from Yageo. Finding a substitute requires careful consideration of either capacitance or package size trade-offs.
AI replacement insight
Package riskhigh
One candidate has matching electricals but a larger 1206 package, requiring a PCB redesign.
Electrical riskmedium
Several candidates match the 0805 package but have a lower capacitance (0.47µF), which may affect circuit performance.
Can it be replaced directly?
No, a direct, drop-in replacement for CC0805KKX7R8BB684 with identical key parameters was not found among the candidates. All options require engineering review.
Best replacement path
If PCB layout can be modified, CC1206KKX7R9BB684 is the best functional match. If the 0805 footprint is fixed, an alternative with different capacitance (e.g., 0.47µF) must be evaluated.
Main risk
The primary risk is either functional change due to capacitance mismatch or physical incompatibility due to package size difference.
