A 120pF, 50V ceramic capacitor in a matching 0402 package with a tighter ±1% tolerance.
Best Alternatives to TCC0402COG121J500AT
TCC0402COG121J500AT is a standard 120pF, 50V, C0G ceramic capacitor in a 0402 package. It is used in applications requiring high stability, such as timing and filtering circuits. Alternatives must match the C0G dielectric to ensure performance.
AI replacement insight
Electrical riskhigh
High if dielectric or capacitance is wrong. C0G is required for stability in many circuits.
Package risklow
Low, as 0402 is a standard SMT package.
Can it be replaced directly?
Direct replacement for TCC0402COG121J500AT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Prioritize candidates with identical C0G dielectric, 120pF capacitance, and 50V rating in a 0402 package, like Yageo's CC0402FRNPO9BN121.
Main risk
The primary risk is substituting with a capacitor that has a different dielectric type (e.g., X7R), which will compromise circuit stability.
