Is there a pin-compatible replacement for 0402CG0R8B500NT?

Yes, several MLCCs in the 0402 package are potential pin-compatible replacements, including RF15N0R8A500 and CQ0402ARNPO9BNR80. As they are 2-pin surface-mount devices, they share the same land pattern.

What risks should I check before replacing 0402CG0R8B500NT?

Key risks include changes in capacitance tolerance. Some alternatives have tighter tolerance (an upgrade), while others have looser tolerance (e.g., ±0.25pF vs ±0.1pF), which could impact the performance of sensitive RF or timing circuits. Always verify the substitute's datasheet.
