52-Position Dual-Row Board-to-Board Receptacle
The 91615-326LF: This is a 52-position dual-row board-to-board receptacle from the Dubox series by Amphenol ICC (FCI). All 52 positions are loaded, so the BOM position count is exactly what it says. Gold at this thickness handles 500+ cycles without exposing the base metal — a solid choice for equipment that sees connector swaps over its service life. Mated stack height is 10.81mm, which sets the z-height budget between the two PCBs in a mezzanine configuration. The receptacle accepts bottom or top entry, so the board stack-up can be arranged with the receptacle on either side.
SMT Termination with Board Lock
Termination is surface mount solder — the contacts are soldered directly to the PCB pads. In a vibration-prone environment, that anchor keeps the solder joints from fatiguing. Insulation color is gray, which helps visual identification on the board.
