Is there a pin-compatible replacement for FCC0603N5R0C500CT?

Yes, several parts like FCC0603N4R7C500CT and 0603CG5R1C500NT share the same 0603 package and pinout, but have slightly different capacitance values that require engineering review.

What risks should I check before replacing FCC0603N5R0C500CT?

The main risk is capacitance deviation. Ensure the new capacitance value (e.g., 4.7pF or 5.1pF) is within your circuit's tolerance, especially for timing or RF applications.
