Is there a pin-compatible replacement for ZX-XH2.54-3PZZ?

Yes, several candidates like ZX-HA2.54-3PZZ, PZ254-1-03-Z-8.5, and HC-2510-3A have the same 3-pin, 2.54mm pitch, straight through-hole configuration and are likely pin-compatible. A full pin-to-pin confirmation requires comparing the mechanical drawings in the datasheets.

What risks should I check before replacing ZX-XH2.54-3PZZ?

The primary risk is mechanical mismatch. Check the candidate's datasheet for housing dimensions, pin length, and PCB footprint to ensure it fits your board. Also, note any differences in contact material (e.g., Brass vs. Phosphor Bronze) which could affect long-term reliability and mating cycles.
