Power pair for a 30 A bus — what this header is
The Molex 1720430201 is a 2-position male-blade header from the Super Sabre 172043 series, built to carry 30 A per circuit at 600 V on a 7.50 mm pitch. The right-angle through-hole orientation puts the blades parallel to the PCB plane, which is how you bring a power pair off the board edge toward a busbar or a mating receptacle in a harness assembly. Silver contact finish at 100.0 µin thickness is the standard choice for this current level — gold would erode under the arc and temperature rise of repeated 30 A mate cycles.
Sizing the board footprint for this power header
At 7.50 mm pitch and 2 positions, the footprint is a single-row pair of through-hole solder tails spaced 7.50 mm apart. The right-angle orientation means the tails emerge on the solder side perpendicular to the blade axis — check your board keep-out for the body depth behind the mounting face. There is no sibling in the Super Sabre 172043 series at the same pitch with a different position count that changes the footprint class; the 2-position is the smallest member, and the same 7.50 mm pitch scales up to higher position counts in the series if your circuit count grows.
