0.80mm Pitch, 40-Position MICTOR Mezzanine Plug
It uses a 0.031" (0.80mm) pitch in a 2-row layout, with outer shroud contacts that guide alignment during mating. The integral ground bus (plane) and board guide are built into the housing — these manage return current for high-speed differential pairs and prevent pin damage during blind-mate assembly. With a mated stack height of 22mm and a height above board of 0.836" (21.23mm), this part is meant for applications where the two PCBs sit a full inch apart, not for tight z-height budgets.
40 Circuits at 0.80mm Pitch — Footprint and Routing
The 0.031" (0.80mm) pitch is the tightest in the MICTOR family, which means the PCB footprint is dense — 20 contacts per row, with the outer shroud adding a keep-out zone around the perimeter. The 2-row layout gives 40 total positions, so this plug carries 20 differential pairs if you route them as signal-ground-signal, or 40 single-ended lines. Surface-mount termination keeps the assembly reflow-compatible, but the fine pitch demands a solder-paste stencil that matches the 0.80mm pad spacing.
22mm Mated Stack — Mezzanine Spacing
The 22mm mated stack height is the defining dimension for this part — it sets the distance between the two PCBs in a mezzanine configuration. At 0.836" (21.23mm) above the board on the plug side, the total height budget needs to account for the receptacle's own height on the opposite board. The board guide and ground bus help with alignment, but the stack height itself drives the enclosure's z-height allowance.
The board guide on the plug aligns the pair before the contacts touch, reducing the risk of stubbing on the fine-pitch terminals. Termination is surface-mount only; there is no through-hole variant in this form factor. The tray packaging is standard for SMT pick-and-place lines.
