Best Alternatives to CC0402JRNPO9BN821
Find the best replacements for the Yageo CC0402JRNPO9BN821, an 820pF 50V NP0/C0G 0402 ceramic capacitor. This guide analyzes pin-compatible parts, functional alternatives, and highlights critical parameters to ensure a successful substitution.
AI replacement insight
Electrical riskhigh
Using a part with an X7R dielectric instead of NP0/C0G will introduce significant capacitance variation with temperature and voltage.
Package risklow
The 0402 package is highly standardized, so physical compatibility issues are unlikely with matching parts.
Sourcing risklow
This is a common capacitor value and package, with multiple vendors offering compatible parts.
Can it be replaced directly?
Direct replacement for CC0402JRNPO9BN821 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The HRE CGA0402C0G821J500GT is the strongest candidate, matching all key parameters of the target Yageo capacitor.
Main risk
The primary risk when substituting this part is choosing a capacitor with a different dielectric, such as X7R instead of NP0/C0G, which would degrade performance stability.
