Is there a pin-compatible replacement for ZX-VH3.96-4PZZ?

B4P-VH(LF)(SN) from JST and CH3.96-4A from CAX are highly likely to be pin-compatible as they share the same 3.96mm pitch, 4-pin configuration. However, always verify the datasheet's mechanical drawing against your PCB layout.

What risks should I check before replacing ZX-VH3.96-4PZZ?

Key risks are mechanical fit and mating compatibility. Verify the substitute's footprint and pin dimensions from its datasheet. Also, ensure it mates correctly with your existing female connector housing.
