Yageo
A form-fit compatible capacitor with higher voltage but lower capacitance.
Reviewing alternatives for the Yageo CC0603JRNPO9BN431, a 430pF 50V 0603 MLCC. Key considerations for substitutes are capacitance value, voltage rating, and dielectric material, as no direct drop-in replacements were found.
Capacitance is a critical parameter and all candidates differ significantly.
All candidates share the same 0603 package, ensuring physical compatibility.
No direct, drop-in replacement was identified in this analysis. All potential candidates have different capacitance values that require careful circuit validation before use.
The best replacement path is to source a capacitor with 430pF capacitance, a voltage rating of 50V or higher, and an NP0 (C0G) dielectric in a 0603 package.
The primary risk is capacitance mismatch. Using a capacitor with a different value can alter filter characteristics, timing constants, or resonant frequencies, potentially causing circuit failure.

|---|---|---|---|---|---|
| Package | 0603 (1608 metric) | 0603 (1608 metric) | 0603 (1608 metric) | 0603 (1608 metric) — Form and fit are identical.; CC0603GRNPO9BN271: Form and fit are identical. | |
| Voltage | 50.0V | 100.0V | 50.0V | 100.0V / 50.0V — Higher voltage rating provides more margin.; CC0603GRNPO9BN271: Voltage rating is identical. | |
| Capacitance | 430.0pF | 330.0pF | 270.0pF | 330.0pF / 270.0pF — Capacitance is ~23% lower. Requires circuit validation.; CC0603GRNPO9BN271: Capacitance is ~37% lower. Requires circuit validation. | |
| Tolerance | 5.0% | 5.0% | 2.0% | 5.0% / 2.0% — Tolerance is identical.; CC0603GRNPO9BN271: Tighter tolerance is an upgrade. | |
