100-Position Mezzanine Receptacle at 0.80mm Pitch
At 0.031" (0.80mm) pitch across two rows, it packs the density needed for high-signal-count parallel boards — think server mid-planes, switch fabrics, or any backplane where routing real estate is tight.
13mm Stack Height — The Z-Axis Budget
This receptacle is specified for a 13mm mated stack height, meaning the distance from the top of the plug-side PCB to the bottom of the receptacle-side PCB when fully mated. That 13mm gap is the dimension you design the board spacing around — too tall and the enclosure bulges, too short and the connector bottoms out. The 0.463" (11.75mm) height above board on the receptacle side alone tells you the plug half takes the remaining height in the stack.
SMT Termination and Board Guide
The board guide feature (a pair of plastic alignment posts) takes the shear load during mating so the fine-pitch solder joints don't take the hit. If your assembly line has pick-and-place, the tube packaging feeds into standard vibratory or tube feeders without a tape changeover.
Gold Plating for Repeated Mate Cycles
Active and RoHS3 Compliant
That means it's a safe BOM line for current and near-future production runs.
