Is there a pin-compatible replacement for FCC0402N180J500AT?

Several parts share the same 0402 package and are form-fit compatible. However, no direct electrical pin-to-pin replacement with 18pF capacitance was identified. All alternatives require review.

What risks should I check before replacing FCC0402N180J500AT?

The main risk is the difference in capacitance. An 18pF capacitor is often used in RF, timing, or filter circuits where value is critical. Using a 15pF or 20pF part could shift frequencies or affect timing. Always verify in-circuit.
