64-Position CHAMP .085 Receptacle — Through-Hole, Gold Contacts
The TE Connectivity 5552246-1 is a 64-position receptacle from the CHAMP.085 series, designed for high-density parallel board-to-board or cable-to-board interconnects in telecom, datacom, and industrial equipment. It uses an outer shroud contact arrangement — the contacts are recessed behind a protective shroud on the mating face, which guides the plug into alignment and shields the contacts from damage during blind mating or vibration.
The tin-underplating and gold top layer are applied over the base copper alloy; the gold is on the mating interface, not the solder tail.
This is a vertical through-hole mount receptacle with a board-side flange — the flange sits flush against the PCB and provides additional mechanical retention against the insertion force of the mating plug. The outer shroud contacts mean the receptacle body extends beyond the contact tips; the board layout must account for the shroud's footprint, not just the pin grid. The part ships in a tray, which is the standard packaging for through-hole connectors of this size to prevent lead bending during handling.
