Is there a pin-compatible replacement for HC-XHB-4Y?

Potentially, yes. Parts like JST XAP-04V-1 and CJT A2501H-4P match the pin count and pitch, making them likely candidates. However, you must compare the datasheets to confirm mechanical dimensions and mating compatibility before considering them pin-compatible.

What risks should I check before replacing HC-XHB-4Y?

The primary risk is mechanical incompatibility. Ensure the replacement housing's dimensions, keying, and locking features match your existing board-side header. Always verify the mechanical drawings in the datasheet before purchasing.
