Is there a pin-compatible replacement for 0402CGR25C500NT?

Yes, many 0402 capacitors are pin-compatible in form and fit. However, no candidates found are electrically identical due to capacitance differences, so they are not 'drop-in' replacements and require engineering review.

What risks should I check before replacing 0402CGR25C500NT?

The main risk is the change in capacitance. You must verify how a higher or lower capacitance affects your circuit's performance, especially in timing, filtering, or RF applications. Also confirm the 50V rating provides sufficient margin.
