17mm Mezzanine Stack — 60 Circuits at 0.80mm Pitch
The 17mm mated stacking height is the defining dimension for this connector — it sets the board-to-board gap and is non-negotiable for the mezzanine pair. The receptacle itself sits 15.75mm above the board, meaning the mating plug (the other half of the stack) adds the remaining 1.25mm. The SMT tails and board guide are the only mechanical features on the footprint — no through-hole anchors, so the solder joints carry the full shear load from any board misalignment during assembly.
