Is there a pin-compatible replacement for FH-00133?

The Ckmtw B-2200S04P-A120 shows strong potential for being a pin-compatible replacement. It shares the same footprint, pin count, and critical dimensions. However, you must verify all mechanical drawings in the datasheet before design-in.

What risks should I check before replacing FH-00133?

Before replacing FH-00133, you must check two key risks. First, ensure the substitute's voltage rating is at least 1000V. Second, verify the insulator height is 8.5mm to ensure proper mechanical fit with the mating part.
