D-Sub Combo Receptacle, 5 Positions (4 + 1 Coax or Power)
The Molex 1731071282 is a D-Sub, Combo receptacle from the FM, FCT 173107 series. It carries 5 positions arranged as 4 signal contacts plus 1 coax or power contact in a 2-row layout, shell size 1 (DE, E) - 5W1. This is the female side — mates with the corresponding D-Sub combo plug. The green insulator and steel, tin-plated shell are standard for this series, and the housing is rated IP20 for indoor use only.
Through-Hole Solder Termination, Vertical Mount
This is a vertical mount orientation, so the connector sits perpendicular to the board, with the mating face pointing upward. The flange feature is housing/shell (unthreaded), meaning the mounting ears on the shell accept screws but are not threaded themselves — you supply the screw hardware for panel or bracket mounting. The contact type is listed as signal and coax or power (not included), so the coax or power contact is a separate insert that fits into the designated cavity. The 5W1 layout means one of the five positions is a larger cavity sized for a coax or power contact, while the other four are standard signal positions. Confirm the specific coax or power contact part number from the FM, FCT 173107 series to complete the assembly.
