The 5041940870: This is an 8-position, single-row, SMT header on 1.25mm pitch — the footprint matches the Micro-Lock 1.25mm receptacle family. The latch lock on the shroud keeps the mated pair engaged when the assembly sees vibration or cable tug.
The PA housing is rated UL94 V-0. Mated stacking height is 7.3mm — confirm the receptacle's mating height matches your board-to-board clearance.
The pitch is 1.25mm (0.049 inches). That's the centre-to-centre spacing of the contacts.
Yes, this header is from the Micro-Lock 504194 series and mates with the matching Micro-Lock 1.25mm receptacle housings. The latch lock on the header engages the receptacle's lock feature.
