HCTL
A functional match from the same manufacturer, but mechanical height and footprint require datasheet verification.
PM254-2-17-Z-8.5 is a 34-pin, 2.54mm pitch dual-row female header from HCTL. Finding a suitable replacement requires careful matching of mechanical dimensions, especially the 8.5mm plastic height and PCB footprint.
Plastic height and footprint are critical and unverified in candidates.
Core electrical specs like pitch, positions, and current are consistent.
Direct replacement for PM254-2-17-Z-8.5 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
First, check the datasheet for HC-JN254-2-17-Z to verify its height. If it is not a match, evaluate Amphenol's 89883-417HLF as a cross-vendor option.
The primary risk is mechanical mismatch. An incorrect plastic height or PCB footprint will prevent proper board assembly and mating with the corresponding male header.
