Is there a pin-compatible replacement for ZX-HA2.54-2PZZ?

Several candidates like XUNPU's WAFER-XH2.54-2PZZ are likely pin-compatible. However, because housing dimensions can vary, you must compare the mechanical drawings in the datasheets to confirm a 1:1 fit before purchasing.

What risks should I check before replacing ZX-HA2.54-2PZZ?

The main risk is mechanical incompatibility. Even with the same 2.54mm pitch, the plastic shroud's height, width, and keying can differ between manufacturers, which could prevent the mating connector from fitting. Always verify dimensions.
