Molex 1731091196 — 9-Position D-Sub Receptacle, Standard DE-9 Layout
The Molex 1731091196 is a 9-position D-Sub receptacle from the FCT 173109 series, using the standard DE-9 shell layout (1, DE, E). It carries 9 female sockets arranged in 2 rows, rated 5A per contact — sufficient for signal-level interconnects and moderate power duty in harness assemblies. The connector terminates via through-hole solder pins and mates with any standard D-sub plug of the same shell size. The shell is steel with tin plating; the machined copper alloy contacts are rated for signal use.
The housing/shell flange is unthreaded, so it accepts standard D-sub backshells or hoods that use 4-40 jackscrews for retention — no threaded insert in the flange itself. The through-hole solder termination is a straightforward board-mount process, compatible with wave or hand soldering.
