M55181/7-03 is the 18-contact member of the MIL-DTL-55181 family — the same heavy keyed shell as the four-contact power versions, but fitted with eighteen size 20 contacts. In a SINCGARS vehicle installation this is the audio/data output connector, so the same connector family carries both the 35 A power pair and the control signals.
The part number decodes in two blocks. The digit after the slash is the configuration — 7 is a plug with 18 pin contacts, and 8 is the matching receptacle with 18 socket contacts. The final two digits are the cable-size designator (01-05) from the specification sheet, so two numbers that differ only in that suffix are different harness entries, not different connectors.
Shells are aluminium alloy with a steel alloy nosepiece, cadmium plated with olive drab chromate as standard; the finish letters used on the family are E (cadmium), N (nickel) and B (RoHS-compliant black nickel). The configuration is a QPL item, so the dash number is supplied identically by every qualified source.
