13-Position Hybrid D-Sub — What You Actually Get
The Molex 1727040013 is a D-Sub, Combo plug with 13 positions arranged as 10 signal contacts plus 3 coax or power cavities — the 13C3 / 13W3 layout. That hybrid arrangement matters: you get the standard DB-25 shell size (3/B) but with three oversized cavities that accept coax or power contacts instead of standard signal pins. Rated 5A per contact, the signal pins carry the current limit — the coax/power cavities handle higher current depending on the contact installed.
Termination and Mating — What It Takes
Termination is solder cup — each contact gets hand-soldered to a 20 AWG wire. The contacts (signal and coax/power) are not included; you order them separately and crimp or solder them before loading into the insert. The plug mounts to the panel via the unthreaded housing/shell flange — you need a screw or rivet through the mounting holes, not a jack-screw. The grounding indents on the shell ensure shield continuity when mated.
