Product details

9-Position D-Sub Plug, Through-Hole, with Grounding Indents

The Molex 1731090856 is a 9-position D-Sub plug (male pins) from the FCT 173109 series, designed for through-hole solder termination to a PCB. It carries a 5 A per-contact current rating, with the limiting factor being the pin density at the board edge rather than the contact itself. The shell is steel with tin plating, and the insulator is glass-filled polyester rated UL94 V-0.

The flange is unthreaded, meaning the mating pair relies on the mating receptacle's hardware (screw-lock or slide-lock) for retention; this plug does not come with integral jackscrews. Termination is through-hole solder — the machined copper alloy pins accept solder wicking into the plated through-hole for a reliable joint. No crimp or press-fit option on this variant.

Frequently asked questions

Does 1731090856 have a grounding indent feature?

Yes, the shell includes grounding indents that mate with the receptacle face to bleed shield current before it reaches the signal pins.
