140-Position Mezzanine Plug at 0.80 mm Pitch
It carries center strip contacts in two rows on a 0.031" (0.80 mm) pitch — the tight pitch packs 70 contacts per row, which defines the board footprint and routing density for the high-count interconnect.
Stacking Height Range — One Plug, Four Gaps
This single plug supports mated stacking heights of 5 mm, 9 mm, 13 mm, and 17 mm. The 0.181" (4.60 mm) height above board of the plug itself is fixed; the variable comes from the mating receptacle's height. That means one BOM line for the plug covers multiple board-spacing configurations, as long as the receptacle half is matched to the target stack height.
