The Molex 1731090069 is a standard-density D-Sub receptacle with 15 positions arranged in two rows. It belongs to the F, FCT 173109 series and uses machined, gold-plated signal contacts terminated via solder cups — a method that lets you hand-wire individual conductors without a dedicated crimp tool, which is useful for prototype runs, field repairs, or low-volume cable assemblies. The shell is steel with a tin finish, and the housing carries an unthreaded flange for panel mounting.
The solder cup termination accepts 20 AWG wire. Because there is no crimp terminal involved, the wire preparation is straightforward: strip, tin, and solder into the cup.
Current Capacity and Contact Design
Each contact is rated for 7.5A. For a 15-position connector, that gives a total current capacity of over 112A if all contacts are loaded simultaneously, but the practical limit depends on the derating curve and the bundle size in the cable assembly. This connector is a solid choice for power distribution within a chassis or for signal lines where the 7.5A per contact provides headroom above the typical 1-3A signal current.
