Same package and dielectric, but lower capacitance requires engineering review.
Best Alternatives to CC1206JKNPOCBN821
Finding a substitute for the Yageo CC1206JKNPOCBN821, an 820pF 1kV NP0 ceramic capacitor, requires careful attention to its stable dielectric. While no direct drop-in replacements were found, several parametric alternatives exist with specific trade-offs.
AI replacement insight
Electrical riskhigh
Replacing NP0 with X7R dielectric introduces instability. Capacitance mismatches also require validation.
Package riskmedium
One candidate has a larger 1210 package, which will not fit the 1206 footprint without a board redesign.
Can it be replaced directly?
No direct, drop-in replacement was found among the candidates. All options have significant differences in capacitance, dielectric material, or package size that require engineering review.
Best replacement path
Search for a 1206, 1kV, NP0/C0G capacitor with a capacitance value as close to 820pF as possible. The candidate CC1206JKNPOCBN561 (560pF) is the closest in form and function but requires validating the lower capacitance.
Main risk
The most significant risk is substituting a stable NP0/C0G dielectric with a less stable X7R type, which can cause circuit malfunction.
