What it is and where it sits in the series
The Molex 1720430602 is the 6-circuit member of the Super Sabre 172043 family — a single-row power header built around a 7.50 mm (0.295-inch) pitch and rated 30 A per circuit at up to 600 V. Silver-plated contacts at 100 µin (2.54 µm) give this series a thicker, harder mating surface than the tin or thin-gold options common at this pitch class, which matters when the connector sees repeated engagement or higher vibration environments. The right-angle through-hole body carries a board-lock feature and a locking ramp on the housing for positive panel retention — the board lock anchors the header to the PCB during wave-solder and the ramp locks the mating half in the field so it can't walk loose under harness pull.
What the ratings mean for your fit
The 30 A per-circuit rating handles mid-power bus distribution comfortably, and the 600 V ceiling covers most AC and DC industrial bus rails in the same assembly. Operating range is -40°C to 125°C, so the LCP glass-filled housing is sized for equipment that runs hot near the power stage — the insulation won't soften at those temperatures. The finger-proof shrouding over the solder tails protects live circuits during handling before the mating half is installed.
Sourcing and compliance
Listed Active with ROHS3 compliance. Confirm position count against your BOM line and verify the mating half before RFQ, since the Super Sabre series spans multiple circuit counts and the right-angle through-hole body is not a universal footprint across the family.
