Board-Stacking Interconnect for High-Speed Differential Pairs
The TE Connectivity 1-1658043-3 is an 84-position differential pair array receptacle from the MICTOR SB series, designed for high-density mezzanine board stacking. The 0.031" (0.80mm) pitch packs 84 contacts into a 2-row layout, with the integral ground bus (plane) providing a low-inductance return path that preserves signal integrity for differential-pair routing. Gold flash on the mating contacts handles the moderate mating-cycle duty of a production board-to-board interconnect. The SMT tails and board guide simplify pick-and-place assembly and alignment during reflow.
Nine Stacking Heights from a Single Receptacle
This receptacle supports mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, 22mm, 25mm, and 30mm. The same PCB footprint works across all nine heights by pairing with the corresponding MICTOR SB plug of the appropriate height. For a board-stacking engineer, this means one receptacle BOM line can serve multiple board-spacing budgets in a chassis — the plug height is the only variable.
