Is there a pin-compatible replacement for WAFER-254W-4A?

While several parts like the Megastar ZX-XH2.54-4PWZ series are form, fit, and functionally similar, true pin-to-pin compatibility requires comparing the datasheet's mechanical drawing to your PCB layout. They are highly likely to be compatible.

What risks should I check before replacing WAFER-254W-4A?

The main risk is mechanical. Ensure the 2.54mm pitch and right-angle through-hole footprint match your layout exactly. Also, be aware of minor differences like housing color which may be relevant for your application.
