80-Position 0.80mm Pitch Mezzanine Plug
At a 0.031" (0.80mm) pitch in a dual-row layout, it packs 80 center strip contacts into a compact SMT footprint — the kind of density you see when routing a mid-plane to a daughtercard through a tight z-height budget. Rated mated stacking heights span 6mm, 10mm, 14mm, and 18mm — one connector part number covers multiple board-spacing requirements, which simplifies BOM management when the same plug is used across different card gaps in a chassis.
The 0.80mm pitch is the defining board-layout constraint. It dictates a fine-pitch SMT footprint with tight trace escape routing between pads — typically requiring micro-vias or blind vias in the breakout region for a dense 80-signal interconnect. The 0.230" (5.85mm) height above board is the plug's own profile; the total mated stack height depends on the mating receptacle's height, with the four specified heights (6mm, 10mm, 14mm, 18mm) covering common mezzanine gaps from low-profile to tall-card clearance.
