Three Power Blades in a Single Row — Pure Bus-Level Interconnect
The TE Connectivity 6450173-1 is a MULTI-BEAM XL receptacle with three female blade sockets arranged in a single row — a dedicated power-only contact layout (3 Power) that carries bus-level current on each blade. Operating temperature spans -20°C to 105°C.
Board Lock and Guide Pin — Assembly and Vibration Anchors
This receptacle includes a board lock and a guide pin. The board lock holds the connector in place during solder reflow and provides mechanical retention against the shear force from a mated cable assembly under vibration. The guide pin aligns the mating plug during blind-mate assembly — a real time-saver on a production line where the connector is not easily visible. Both features are standard on MULTI-BEAM XL power connectors that see use in server PSUs, base-station power distribution, and battery interconnect trays.
How It Compares — 6450173-1 vs. 2-1437357-0
The real difference is current capacity: the 2-1437357-0 is rated 28 A per contact, while the 6450173-1 does not have a published per-contact current rating in the spec record. If your design needs a guaranteed 28 A per blade, the 2-1437357-0 is the documented choice; if you are working from a known system current and the Bulk packaging suits your line, the 6450173-1 is the active-production option. Both use the same right-angle through-hole footprint and gold contact finish, so the board layout is interchangeable.
