What this 1.25 mm pitch SMT header fits
The 5054331071 is a 10-position, 2-row SMT header from the Molex Micro-Lock PLUS 505433 series. The 1.25 mm pitch is the first thing to check against your PCB footprint — it is not compatible with the common 2.54 mm or 2.00 mm grid. The shrouded-4 wall design and latch holder fastening lock the mating receptacle in place, making this a vibration-resistant connection for automotive, industrial, and general-purpose applications.
Confirm the mating Micro-Lock PLUS receptacle and terminal part numbers for the full wire-to-board assembly.
The solder retention feature helps hold the part during reflow.
