Is there a pin-compatible replacement for 0402CG4R0C500NT?

Yes, several capacitors share the same 0402 package and 2-pin layout. However, you must verify that their electrical characteristics (capacitance, voltage, dielectric) meet your circuit's requirements.

What risks should I check before replacing 0402CG4R0C500NT?

Before replacing, verify that the small capacitance difference (e.g., 3.9pF vs 4.0pF) is acceptable for your application, especially in RF filters, oscillators, or timing circuits where precision is critical.

AI replacement insight

Electrical risklow

Key parameters like voltage, dielectric, and tolerance are well-matched. Capacitance is very close.

Package risklow

All strong candidates use the same 0402 surface-mount package, ensuring physical compatibility.

Can it be replaced directly?

Yes, several functional alternatives exist with nearly identical parameters, such as Yageo's CC0402CRNPO9BN3R9 or Fenghua's own 0402CG3R9B500NT.

Best replacement path

Select a C0G/NP0 capacitor with 3.9pF capacitance, a 50V rating, and an 0402 package. These are widely available from multiple manufacturers.

Main risk

The primary risk is a minor capacitance deviation (e.g., 4pF vs 3.9pF), which may impact performance in sensitive RF or timing circuits.

Recommended alternatives

A strong alternative with a tighter tolerance, identical package, voltage, and dielectric.
