Is there a pin-compatible replacement for 0402CG1R0C500NT?

Not verified. Some 0402 two-terminal MLCCs look compatible, but pin-to-pin status is not confirmed.

What risks should I check before replacing 0402CG1R0C500NT?

Check capacitance, C0G dielectric, 50V rating, 0402 footprint, temperature range, and circuit sensitivity.

0402CG1R0C500NT is an active FH 1pF 50V C0G 0402 MLCC. The closest listed alternative still needs FAE review.

1pF C0G must be preserved for tuned nodes.

0603 option is not 0402 footprint-compatible.

TDK candidates are obsolete and rejected.

No verified pin-compatible replacement is confirmed from the supplied data.

Review Yageo CC0402BRNPO9BN1R0 first, then same-family value neighbors only if capacitance can change.

Capacitance and footprint changes can alter circuit behavior.

Yageo CC0402BRNPO9BN1R0 is the closest 1pF C0G 0402 candidate.

0603CG1R0C500NT matches 1pF C0G electrically but requires package review.

0402CG1R5C500NT is a same-package value-neighbor, not a direct 1pF match.

0402CG1R8C500NT is a same-footprint relaxed-value option with high electrical risk.
