42-position dual-row receptacle for board-to-board stacking
The 4-1734506-4 is a 42-position, dual-row board-to-board receptacle from the TE AMPMODU series. It mates with a matching 2.00 mm pitch pin header to create a separable connection between parallel PCBs. The through-hole solder tails are tin-plated at 80.0 µinch (2.03 µm) and extend 0.102" (2.60 mm) below the insulator, giving a solid solder joint into the plated through-hole on the PCB.
Pitch, row spacing, and board footprint
Mating pitch is 0.079" (2.00 mm) with an identical 0.079" (2.00 mm) row spacing — the contact grid is a tight 2 mm square array that routes well on two-layer boards if the trace width stays under 0.25 mm between pads. All 42 positions are loaded; no optional or dummy positions.
ROHS3 Compliant per current TE documentation.
