Decode an existing part number
Build a new part number
Each sheet offers two classes: D and G on /1-/4, M and N on /5-/8, H and K on /9. D, M and K are the space-mission versions of G, N and H (1.3.1, p.2).
Picking an insert arrangement above sets this automatically, or choose a shell size here first to narrow the arrangement picker.
A is rigid mounting; the other details are floating mounting bushings. Detail B is inactive for new design on most sheets.
Crimp sheets only (/2, /4, /6, /8): the connector with its contacts, a kit (connector with contacts and tool), or the connector without contacts.
Sheet /9 only: solder cup or eyelet. It is not a letter in the part number; the dash number carries it.
Classes G and N only. Classes D, M, H and K take no letter (1.2, p.1).

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-24308 covers rectangular, miniature, polarized-shell connectors, the D-subminiature family, in six shell sizes with standard density inserts (size 20 contacts) and high density inserts (size 22D contacts). This builder covers the nine connector sheets M24308/1 to /9: receptacles with socket contacts and plugs with pin contacts, solder and crimp, general purpose, nonmagnetic and hermetic.
The dash number of a M24308 part number carries the shell size, insert arrangement, class, mounting detail and what is supplied, so the builder looks it up in each sheet's table and lists only the combinations the sheet gives. A finish letter follows it for classes G and N. The SAE replacement documents were not read: check a part number against the current revision.
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, screw locks and crimp contacts for the connector you built, and builds each accessory’s part number for that connector’s shell size as you pick its options.
Build or decode a part number
Choose the options one field at a time, or paste a part number such as M24308/2-361F 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.
