Is there a pin-compatible replacement for 2541WV-04P?

Liansheng's FH-00133 appears to be pin-compatible based on datasheet comparison of pitch, pin count, and housing dimensions. However, always verify the full mechanical drawing against your PCB layout before production.

What risks should I check before replacing 2541WV-04P?

Key risks include mechanical fit, especially the connector's height (profile), and electrical ratings. Ensure the substitute's voltage rating meets or exceeds the target's 550V and that contact plating is compatible.
