What it is and where it sits in the series
The Molex 0464379308 is the 8-circuit member of the EXTreme Ten60Power 46437 series — a high-current board-level power plug rated 60A per circuit at up to 600VAC or 250VDC. Gold-over-nickel contacts at 30µin (0.76µm) thickness sit behind a black UL94 V-0 housing with an integral board guide and guide pin that take the guesswork out of alignment during assembly. Press-fit tails eliminate solder operations and carry the full current load through the plated-through hole interface — the termination style that makes this connector suited for busbar-to-board power distribution rather than low-level signal daisychaining.
What the ratings mean for your fit
At 60A per circuit this is a power-delivery interconnect, not a signal header — the current rating governs wire gauge and busbar ampacity upstream, not just the board trace width. The 0.217 inch (5.50 mm) pitch is wider than standard board-to-board signal headers and provides the contact spacing needed to avoid arc-tracking at full voltage under fault conditions. All 8 positions are loaded, so there is no partial-population flexibility — the circuit count commits to an 8-way power bus or a dual-feed leg pair depending on how the system splits the load. The press-fit termination requires a properly sized plated-through hole on the board; verify the hole diameter and plating specs against the Ten60Power datasheet land pattern before releasing to fab. The right-angle orientation places the mating face perpendicular to the board surface, routing the power bus along the plane of the PCB — a layout choice that saves vertical z-height compared to a vertical plug but requires adequate lateral board space for the plug body depth. The board guide and guide pin mechanically locate the housing before the contacts engage, protecting the gold plating from stub damage during field service or blind mating.
