Is there a pin-compatible replacement for ZX-ZH1.5-4PWT?

No pin-to-pin compatible replacement is confirmed. A1501WR-S-4P shares the same pitch and pin count, but its PCB footprint and mating compatibility must be verified against the datasheet as it is from a different series.

What risks should I check before replacing ZX-ZH1.5-4PWT?

Key risks are: 1) Pitch mismatch, preventing PCB mounting. 2) Footprint mismatch, requiring board redesign. 3) Lower voltage ratings, causing electrical failure. 4) Mating incompatibility with the existing housing.

ZX-ZH1.5-4PWT Alternatives, Datasheet & Cross Reference | Megastar
