Yageo 3pF 50V C0G 0402 is a strong candidate with tighter tolerance.
0402CG3R0C500NT is a 3pF 50V C0G 0402 MLCC. The closest listed candidate is a tighter-tolerance Yageo 3pF 0402 part, pending FAE review.
Yageo match lacks temp field; other parts change capacitance.
Kept candidates list 0402 and 2 terminals.
Passive MLCC; no firmware interface.
Cross-vendor qualification may be needed.
No datasheet-verified pin-compatible replacement is confirmed from the provided fields.
Review CC0402BRNPO9BN3R0 first; it matches 3pF, 50V, C0G and 0402 with tighter tolerance.
Changing capacitance from 3pF can detune RF or timing networks.
