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.","metaTitle":"Molex 1731091391 D-Sub Plug, 25-Pin, DB-25, Solder Cup","metaDescription":"Molex 1731091391 FCT D-sub plug, 25 male pins, DB-25 shell, 5A, solder termination, UL94 V-0.
