Is there a pin-compatible replacement for KY1102M400VAC70Y10093?

Yes, KNSCHA AJTF222M2GF0200A082E has the same 10mm lead pitch and through-hole package. However, its capacitance is higher, so it is not an exact electrical drop-in.

What risks should I check before replacing KY1102M400VAC70Y10093?

Ensure the replacement has a Y1 safety rating and a voltage rating of at least 400VAC. Verify the lead pitch (10mm) for physical fit. Check if any capacitance difference is acceptable for your application's filtering requirements.
