Is there a pin-compatible replacement for 0402N180J500CT?

While no exact drop-in replacements are listed, several parts like Yageo's CC0402GRNPO9BN200 share the 0402 package. However, their capacitance values differ, requiring circuit validation.

What risks should I check before replacing 0402N180J500CT?

The main risk is capacitance mismatch. The target is 18pF; substitutes may have 20pF or 22pF. This can affect timing, filtering, or resonance in sensitive circuits. Always verify.
