46-Position Dual-Row Receptacle for Board-to-Board Stacks
The 93696-323LF is a 46-position, dual-row board-to-board receptacle from the Amphenol ICC Dubox series.
With a 0.275" (6.99 mm) insulation height, the receptacle sits low on the board, keeping the mated stack height within a tight z-budget for mezzanine or card-edge applications. The dual-row, 46-position layout packs 23 contacts per row, which demands careful trace routing to avoid congestion between the two rows. The through-hole solder posts (tin finish, 2.00 µm thick) require plated through-holes in the PCB — the hole diameter and pad size must match the post dimensions from the product drawing to ensure reliable solder fillet formation.
The female socket contacts accept square pins from the mating header. The gold-on-gold interface (30 µinch on both sides) keeps contact resistance stable over the rated mating cycles.
