Is there a pin-compatible replacement for 1.25-4PWB?

Several parts like WAFER-MX1.25-4PWB and ZX-MX1.25-4PWT appear to be form, fit, and function compatible. However, pin-to-pin compatibility requires careful comparison of the mechanical drawings and PCB land patterns in the datasheets.

What risks should I check before replacing 1.25-4PWB?

The primary risk is mechanical mismatch. Verify the connector's footprint, height, and mounting tab dimensions against your PCB layout. Also, confirm compatibility with the mating connector series.
