5-position single-row header with latch holder
The 1053092105 is a Molex Nano-Fit 105309 series header, 5 positions in a single row, 2.50 mm pitch. The shrouded 4-wall housing and latch holder keep the mated pair engaged under vibration — a half-turn loose is a dropout, but here the latch clicks home and stays.
The post length is 0.126" (3.20 mm), which fits standard 1.6 mm PCBs with enough tail for a solid fillet. Mated stack height is 21.30 mm with the matching Nano-Fit receptacle, so plan your z-height budget around that number.
