Product Overview
The 7.50 mm pitch supports the voltage rating. Silver plating at 100.0 µin.
The 1720430606 shares the same 6-position count, 7.50 mm pitch, 30 A rating, silver plating, and locking ramp, but it's a right-angle through-hole header with board locks. The 1720420601 is straight through-hole without board locks. If your board layout needs the header to sit parallel to the PCB to clear an enclosure wall, the 1720430606 is the one; if you need a vertical header for a top-down harness drop, stick with the 1720420601. Both are active, so you can source either against your BOM.
