25-Pin D-Sub Receptacle, Solder Cup Termination
The Molex 1727040070 is a 25-position D-sub receptacle from the F, FCT 172704 series, terminated via solder cups for field-repairable cable assembly. The white shell colour distinguishes this variant for visual harness identification.
Mates with a male plug having the 3 (DB, B) shell layout. The free-hanging (in-line) mounting and unthreaded housing shell mean no panel cutout is required for basic cable-to-cable connections; if panel mounting is needed, a mating connector with threaded inserts or a separate screw-lock kit is used. The 2-row, 25-contact layout is the standard DB-25 footprint, so it crosses into the harness you've already got if you're replacing a 25-pin female D-sub.
Termination and Field Service
Solder cup termination means this connector can be re-pinned on site with a soldering iron and basic kit — no crimp tool required. The brass contacts with gold finish handle the heat of soldering without degrading the mating surface. For a field-service swap, trim the old wires, tin them, and solder into the cups; the 20 AWG wire gauge is a comfortable size for hand soldering. The polybutylene terephthalate (PBT) dielectric handles the soldering iron temperature without damage if you work quickly.
