The Molex 1054440001 is a USB Type-C plug connector from the 105444 series, designed for board-edge straddle-mount applications. It carries the full 24-contact complement of the USB-C standard, supporting USB 3.2 Gen 2 (10 Gbps) data rates alongside power delivery up to 5 A per contact at 30 VAC/DC. The shielded steel and stainless shell provides EMI containment for high-speed signal integrity, while the gold-plated contacts handle the 10000 mating cycles the connector is rated for — a durability figure that suits field-serviceable equipment or docking stations where repeated connect-disconnect is expected.
What the 10000 Mating Cycles Mean for Your Design
The 10000-cycle rating is well above the USB-IF minimum of 10000 for standard USB-C connectors, which means this plug is specced for the full durability requirement of the Type-C ecosystem. For a board-edge connector that sees daily plug-unplug cycles — think test equipment, public kiosk ports, or industrial handhelds — that cycle life translates to years of reliable service before contact wear becomes a concern.
This plug uses a board-edge, straddle-mount configuration — the connector straddles the edge of the PCB, with solder terminals on both top and bottom board surfaces. That mounting style is common for USB-C receptacles that need to sit flush with the board edge for enclosure cutouts. Termination is solder-only; no press-fit option. The connector ships in tray packaging, which is typical for manual or low-to-mid-volume assembly lines.
