Finding a substitute for the FN18X104K500GBG 100nF 50V 0603 capacitor is straightforward due to its common specification. Key is to match the 0603 package, 100nF capacitance, and X7R dielectric, while ensuring any alternative has a voltage rating of 50V or higher.

AI replacement insight

Electrical riskhigh

Using a part with voltage < 50V can lead to immediate failure.

Package risklow

The 0603 package is standardized, making physical fit straightforward.

Sourcing risklow

This is a very common capacitor value with many manufacturers.

Can it be replaced directly?

Yes, several direct replacements exist. CL10B104KB8NFNC from Samsung is an ideal candidate, matching the 100nF capacitance, 50V rating, ±10% tolerance, and 0603 package.

Best replacement path

Upgrade to a 100V-rated part like HMK107B7104KAHT for a wider safety margin, or use CL10B104KB8NFNC for a direct parametric match.

Main risk

The primary risk is using a substitute with a lower voltage rating or a wider tolerance (e.g., ±20%) without verifying its suitability for the specific circuit application.
