A 0402 capacitor with same voltage and dielectric, but lower 220pF capacitance. Requires circuit analysis.
Finding a substitute for the FCC0402B331K500AT 330pF capacitor requires careful review. While several 0402 50V X7R capacitors exist, most have different capacitance values that demand circuit validation.
Lower capacitance will alter filter frequencies, timing constants, or decoupling effectiveness.
All candidates share the same 0402 package, ensuring physical compatibility.
No direct, fully equivalent replacements for FCC0402B331K500AT were identified. All reviewed candidates have lower capacitance, which requires engineering validation before use.
The closest options are 220pF capacitors like TCC0402X7R221K500AT, but this is a significant parametric change. No direct drop-in replacement was found.
Electrical performance degradation due to lower capacitance.
