The 826467-7: The shroud is a 2-wall design with a latch holder, so the mating receptacle locks in place and won't back out under moderate vibration. Style is listed as board-to-board or cable — it can mate with a board-mount receptacle or a crimp-to-wire housing that accepts the same 0.100" pitch. The latch holder is on the header body, so the mating half needs the corresponding latch slot.
Material and environmental limits
Housing is glass-filled PCT, rated UL94 V-0. Contacts are phosphor bronze — a standard spring alloy that holds up under repeated insertion.
How it compares to 1394090-1
If your board layout needs a right-angle exit or a slightly wider pitch, that part is worth evaluating; for a 7-position vertical header at 0.100" pitch with gold mating, 826467-7 is the direct fit.
