FH 0402CG3R0C500NT is a same-series 3pF option needing circuit review.
0402CG3R9C500NT is a 3.9pF 50V C0G 0402 MLCC. The listed alternates are same-series values, not confirmed drop-in replacements.
3pF/5pF change circuit behavior.
0402 and 2 terminals match.
Passive MLCC.
Exact value not provided.
No confirmed pin-compatible 3.9pF replacement is in this set.
Use the exact 3.9pF part if possible; otherwise review 3pF or 5pF with circuit retuning.
Capacitance mismatch.
