What This D-Sub Combo Housing Does in the Assembly
The Molex 1727040038 is a D-Sub combo receptacle housing from the FM, FCT 172704 series. It accepts female coax or power contacts in an 8-position 8W8 layout — shell size 4 (DC, C). This is the housing half of a mixed-signal or power interconnect, not a standard signal-only D-Sub. The free-hanging (in-line) mount suits it for cable-to-panel or cable-to-cable harnesses where you need to route coax or heavier-gauge power lines through a single connector shell. The green polyester glass-filled dielectric housing carries the contacts and provides the keying and polarization of the D-Sub interface.
Shell Size and Contact Compatibility
The shell size is 4 (DC, C) with an 8W8 connector layout — this is a standard D-Sub footprint dimension, meaning it mates with any 8W8 D-Sub combo plug of the same shell size. The 8 positions are arranged as a single row of coax or power contact cavities. The steel shell with tin plating provides EMI shielding and mates with the corresponding plug shell.
Temperature Rating and Compliance
It is ROHS3 Compliant. The dielectric material is polyester, glass filled. The product status is Active.
This is a housing-only part — the buyer must source the matching coax or power contacts separately. The 1727040038 is an active, in-production Molex part.
