Is there a pin-compatible replacement for CGA0402X7R151K500GT?

No, a direct pin-to-pin replacement with identical key parameters was not identified. While several candidates share the same 0402 package and pinout, they have different capacitance values or dielectric materials, which requires engineering validation before substitution.

What risks should I check before replacing CGA0402X7R151K500GT?

Before replacing, you must verify your circuit's tolerance for changes in capacitance and dielectric type. A different capacitance can alter filter frequencies or timing constants. A different dielectric (like C0G instead of X7R) will change the capacitor's stability with temperature and voltage.
