Is there a pin-compatible replacement for PX684K2C1502?

Several parts share the same 2-pin radial package with a 15mm lead pitch, making them physically compatible. However, none match all key electrical parameters.

What risks should I check before replacing PX684K2C1502?

Key risks: 1) Ensure the replacement has an X2 safety rating. 2) Verify the AC voltage rating is at least 310VAC. 3) Assess the impact of capacitance differences on EMI filtering.
