292173-4 is a 4-position SMT box-type horizontal mount header from TE Connectivity's AMP CT connector series, designed for wire-to-board interconnect applications. This header features tin plating, solder tabs for secure PCB mounting, and a locating boss to help orient the header onto the PCB. The connector operates at 2.0 mm pitch and is part of a miniature interconnect solution with box headers that offer front and back wall polarization for reliable mating. It is compatible with MT housings (173977, 179694) or crimp housings (179228) with contacts, providing flexibility in harness-making applications. Common applications include digital data networks and general-purpose wire-to-board connections where compact, reliable interconnects are required.
