MIL-DTL-83723 Series III Part Number Builder

M83723/65–/98 environment-resisting and hermetic receptacles and plugs, bayonet and threaded coupling

Decode an existing part number

Build a new part number

Each sheet offers the classes in its own title. Table I of MIL-DTL-83723H gives each class's shell material, finish and temperature rating.

    Picking an insert arrangement above sets this automatically — or choose a shell size here first to narrow the arrangement picker.

    N is the normal position and is written in the part number. Positions 1 to 5 turn the insert and are inactive for new design; 6 to 9 and Y move the minor keys (MIL-STD-1554A figure 1). Shell size 8 has no 1 to 5 or Y.

    Accessories

    Parts list

    Tick “Add to parts list” next to any part number above: the connector, its contacts, a mate or an accessory, as you build other connectors. Contact quantities are for one connector; edit the quantity for more. The list clears on reload — copy or download it before you leave the page.

    No parts yet.

    Copy list gives part number, quantity and description separated by tabs, for a spreadsheet or a distributor’s paste-a-list form. The CSV has the same columns with a header row.

    Check every part number and quantity against the current specification before you buy. Neither this site nor Newark is responsible for errors in generated part numbers; see Part numbers and purchases.

    About this builder

    MIL-DTL-83723 Series III connectors are circular connectors with bayonet or threaded coupling and crimp contacts. This builder covers 33 specification sheets from M83723/65 to /98: flange-mount and jam-nut receptacles, plugs, RFI plugs, self-locking plugs, push-pull plugs and hermetic receptacles.

    Find the mating connector

    Build or decode a part number and the builder lists its candidate mating connectors: a plug for a receptacle or a receptacle for a plug, with the same shell size, insert arrangement and polarization or insert position, and the opposite contacts, pins to sockets. Similar plating and Similar contacts narrow the list, and Hermetic switches to the hermetic mates. Add a mate to the parts list with one click, and check it against both detail sheets before you use it.

    Accessories that fit

    The Accessories panel lists the backshells, receptacle adapters, seal plugs, protective covers and dummy stowage receptacles for the connector you built, and builds each accessory’s part number for that connector’s shell size as you pick its options. Its Dust Caps section names the plastic dust cap the specification calls for, M85049/138, with its status; that sheet is SAE-only, so its part numbers aren’t built here. See M85049 accessories.

    Build or decode a part number

    Choose the options one field at a time, or paste a part number such as M83723/75W1006N into Decode to see what each part of it means. Each list offers only the options the specification allows with your earlier choices. Tick “Add to parts list” to collect the connector, its contacts, mates and accessories as you go, then copy the list or download it as CSV.
