9-Position D-Sub Receptacle, Through-Hole Solder
The Molex 1731091176 is a 9-position D-sub receptacle from the F, FCT 173109 series, fitted with female machined signal contacts in a 2-row layout. This is the standard DE-9 (E shell size) footprint — the same mechanical interface used on RS-232 ports, industrial machine I/O, and instrumentation panels.
What the 5 A Rating Means for Signal vs Power Duty
5 A per contact is the standard signal-level current for a machined-contact D-sub at this density. The 9-position layout keeps contact-to-contact spacing generous enough that the current limit is set by the contact itself, not by temperature rise in the dielectric.
Mating and Shell Compatibility
The unthreaded housing accepts a standard D-sub backshell kit (screw-lock or slide-lock); the 4-40 threaded inserts on the mating plug are not present on this receptacle side, so the cable-side hardware provides the locking force. Shell size 1 (DE, E) is the same footprint used across the FCT 173109 series for all 9-position variants.
