Board-to-board header for mezzanine stacking
The 90098-105LF is a 10-position, dual-row header from the Rib-Cage III series, on a 0.050" (1.27mm) pitch — a common footprint for compact mezzanine interconnects. It is a shrouded (4-wall) male pin header, surface-mount terminated, with a mated stack height of 8.26mm.
Pitch, stack height, and footprint match
The 0.050" (1.27mm) pitch and 0.050" row spacing mean the footprint occupies a 5 x 2 grid of pads on a 1.27mm pitch — verify your PCB layout matches this grid. The 8.26mm mated stack height is fixed by the header's insulation height of 0.298" (7.57mm) and the mating contact length of 0.130" (3.30mm). This is the z-height budget between your two boards.
Housing material is UL94 V-0 rated glass-filled thermoplastic.
