The 796642-8 is a Buchanan-series terminal block header — 8 circuits on a single level, 5.00 mm pitch, vertical orientation, shrouded on four sides. It mates with the corresponding 5.00 mm plug or receptacle, and the 0.138-inch (3.50 mm) solder tail length suits standard 1.6 mm PCBs where the header sits flush on the board surface.
At 5.00 mm pitch, the 8-position header occupies about 40 mm of board edge — a standard footprint for 5 mm terminal blocks. For a 12 AWG wire at 25°C ambient, the 15 A rating holds without thermal concern. The vertical orientation means the header stands perpendicular to the PCB. This is the most common orientation for wire-to-board terminal blocks where the wire entry is from above, and it keeps the z-height budget at the insulation height of 0.472 inches (12.00 mm) plus the plug height.
