Press-Fit Power Receptacle for Backplane and Busbar Distribution
The TE 6450553-2 is a 6-position receptacle from the MULTI-BEAM XL series, designed as a pure power interconnect — the contact layout is 6 power positions with no signal pins mixed in. It uses press-fit termination into a through-hole PCB, which means no solder joints and a rework-friendly assembly that handles the mechanical loads of a backplane or power distribution board. The housing carries a board lock and a guide pin to register the connector during press-in and keep it seated against vibration.
Why Press-Fit Matters for This Connector
Press-fit termination eliminates the thermal stress of wave soldering and the risk of solder voids in high-current paths. The compliant pin deforms elastically into the plated through-hole, creating a gas-tight joint that handles the 200V rating and the mechanical shear from the mating header. Board lock features on the housing add retention during the press operation — without them, the connector could push back out of the board if the press tooling isn't aligned to the guide pin.
The key difference is current rating: the 2-1437357-0 is rated 28 A per contact, while the 6450553-2's current rating is not specified in the listing — the 6 power positions and 200V rating suggest a similar power-class duty, but the exact per-contact current should be confirmed from the full datasheet for your derating calculation. Both are active in production.
