Yageo CC0603BRNPO9BN4R3 is a strong pin-compatible alternative with matching key parameters and a tighter tolerance.
Finding a substitute for the FH 0603CG4R3C500NT 4.3pF 50V C0G capacitor requires matching its package, voltage, and stable dielectric. Several alternatives exist, with the best options offering identical or tighter specifications.
Low if sticking to C0G/NP0 dielectric and matching capacitance/voltage.
Low, as 0603 is a standard package.
C0G capacitors in this range are widely available from multiple vendors.
Direct replacement for 0603CG4R3C500NT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The most direct replacement is Yageo CC0603BRNPO9BN4R3, which is a pin-to-pin match with improved tolerance.
The main risk is using a part with a different capacitance or a less stable dielectric (like X7R/X5R), which can affect circuit performance.

|---|---|---|---|---|---|
| Package | 0603 | 0603 (1608 Metric) | 0603 | 0603 (1608 Metric) — Matches standard 0603 footprint.; 0603CG4R0C500NT: Matches standard 0603 footprint. | |
| Capacitance | 4.3 pF | 4.3 pF | 4.0 pF | 4.3 pF / 4.0 pF — Identical capacitance value.; 0603CG4R0C500NT: Slightly lower capacitance, requires review. | |
| Voltage | 50 V | 50 V | 50 V | 50 V — Identical voltage rating.; 0603CG4R0C500NT: Identical voltage rating. | |
| Dielectric | Class I (C0G) | NP0 (C0G) | Class I | NP0 (C0G) / Class I — Equivalent stable Class I dielectric.; 0603CG4R0C500NT: Equivalent stable Class I dielectric. | |
| Tolerance | ±0.25 pF | ±0.1 pF | - | ±0.1 pF — Tighter tolerance is a performance upgrade. |
Verified drop-in options for 0603CG4R3C500NT are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
