Is there a pin-compatible replacement for CGA0402C0G680J500GT?

Yes, several capacitors share the 0402 package and pinout. However, they differ in capacitance. Any pin-compatible option must be reviewed by an engineer to ensure the capacitance change is acceptable for the application.

What risks should I check before replacing CGA0402C0G680J500GT?

The primary risk is the change in capacitance. Using a capacitor with a different value can affect timing, filtering, or impedance matching in your circuit. Always verify the new capacitance value is within your design's tolerance.
