What the 1726723003 Is and Where It Fits
The Molex 1726723003 is a 3-circuit Super Sabre receptacle housing designed for high-current wire-to-wire or wire-to-board power interconnects. It uses a 7.50 mm pitch — wide enough to handle the 34 A per circuit rating without excessive creepage concerns, and common in battery, power distribution, and industrial control harnesses. The housing is a free-hanging, in-line receptacle that accepts female blade socket crimp terminals (sold separately). The latch lock fastening provides positive retention against vibration and shock, making it suitable for automotive under-hood or heavy equipment environments. The polyamide insulation carries a -40°C to 125°C operating range, covering most sealed and unsealed under-hood applications.
Key Ratings and What They Mean for Your Build
The 34 A per circuit rating is the headline — this is a power connector, not a signal interconnect. Each circuit can carry bus-level current, so the mating terminal and wire gauge must be sized accordingly. The 7.50 mm pitch gives enough room for the large-gauge wire and the contact beam needed to sustain that current without overheating. Because contacts are not included, you must order the matching female blade socket crimp terminals separately. This is a standard practice for power connectors where the terminal is application-specific (wire gauge, plating, pull force). Confirm the terminal part number for your wire size before committing the BOM.
Mating and Termination
This receptacle mates with the corresponding Super Sabre male header or plug housing (same series, 3 circuits, 7.50 mm pitch). The latch lock engages audibly for a positive mate. Termination is crimp-style — the housing accepts pre-crimped female blade socket terminals that are inserted and retained by the latch.
Lifecycle and Sourcing
The 1726723003 carries an Active lifecycle status and is ROHS3 compliant. It is sourced to order against an RFQ through independent distribution — availability and current pricing are confirmed at quote time. No official cross-reference or successor is on record; the part is specified as-is for the BOM.
