What it is
The Molex 1720430206 is a 2-circuit, single-row male header in the Super Sabre 172043 series, right-angle mounted with through-hole solder termination. At 7.50 mm pitch it sits in the mid-range power-header class — large enough for meaningful current, compact enough for dense board layouts. The locking ramp on the housing body provides the primary retention latch against the matching receptacle; the board-lock feature adds shear resistance at the PCB interface once placed. The finger-proof shroud protects against accidental contact with live blades during handling or in-field service.
Ratings and what they mean
The 30 A per-contact current rating at 600 V makes this a true power-interconnect member — not a signal header wearing a high-amp number. The 100 µin (2.54 µm) silver contact plating over copper is the detail that earns that rating: thick silver handles the oxide cycles and current density without the micro-fretting wear you'd get from thin tin. The operating range of -40°C to 125°C covers the full industrial envelope; no derating curve is on record, but the 125°C ceiling is the binding constraint at full current in enclosed panels.
Compliance and sourcing
The part is Active and carries ROHS3 compliance — no EOL notice, last-time-buy flag, or NRND entry listed. No official cross-reference or pin-compatible substitute is listed for the Super Sabre 172043 series; the standard path for an alternate is the same series at a different position count, which requires confirming pitch and keying match the board footprint. Sourced to order against the BOM quantity on an RFQ basis.
