What risks should I check before replacing TCC0402COG4R7C500AT?

Verify secondary parameters like ESR, Q-factor, and the exact temperature coefficient curve from the datasheets. While C0G/NP0 dielectrics are very stable, minor differences can be critical in high-frequency RF or precision timing circuits.

TCC0402COG4R7C500AT Alternatives, Datasheet & Cross Reference | CCTC

TCC0402COG4R7C500AT is a standard 4.7pF, 50V, C0G dielectric ceramic capacitor in a 0402 package. Several pin-compatible alternatives with matching or better electrical parameters are available from other major manufacturers.

AI replacement insight

Electrical risklow

Key parameters match, but secondary characteristics should be verified from datasheets for sensitive applications.

Package risklow

All strong candidates use the standard 0402 package, ensuring physical compatibility.

Can it be replaced directly?

Direct replacement for TCC0402COG4R7C500AT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use a parametrically identical part like Yageo CC0402CRNPO9BN4R7 or Samsung CL05C4R7CB5NNNC for a direct swap.

Main risk

Subtle differences in secondary characteristics like ESR or Q-factor, which can matter in sensitive RF or timing circuits.

Recommended alternatives

A pin-compatible 4.7pF 50V 0402 capacitor from Yageo with matching key electrical parameters.
