Is there a pin-compatible replacement for ZX-XH2.54-4PWT?

ZX-HA2.54-4PWT is potentially pin-compatible, but as it belongs to a different series (HA vs. XH), its housing dimensions and keying must be carefully checked against the PCB layout before considering it a drop-in replacement.

What risks should I check before replacing ZX-XH2.54-4PWT?

The main risk is mechanical incompatibility. Verify the connector pitch (2.5mm), mounting style (right-angle SMT), and the exact housing dimensions from the datasheets to ensure it fits your PCB layout and mates with the corresponding cable connector.
