Product details

DB-25 Plug, 25 Male Pins, Solder Termination

The Molex 1731091391 is a 25-position D-Sub plug (male pin) from the F, FCT 173109 series, built in the standard DB-25 shell size — layout 3 (DB, B). It carries 25 machined copper alloy signal contacts rated 5 A each, terminated via solder cups for through-hole mounting.

25 Positions, DB-25 Shell, 5 A Signal Duty

The unthreaded housing/shell flange accepts standard D-sub hardware (slide locks or screw-locks, not included). Termination is solder cup — the machined pins accept 20-28 AWG stranded wire for hand or wave soldering. The through-hole mounting legs stabilise the connector during soldering and provide mechanical retention to the PCB.

Frequently asked questions

Is 1731091391 compatible with standard D-sub backshells?

Yes — the DB-25 shell size and unthreaded flange are standard for D-sub backshells. Any backshell designed for a DB-25 male connector with solder-cup contacts will fit, provided it accommodates the through-hole mounting legs.
