Micro-D MIL-DTL-83513 Microminiature Rectangular
A microminiature rectangular connector on .050 inch contact spacing. As an Amphenol authorized distributor, ADMTEC supplies the M83513 family in Korea and handles the connectors, EMI backshells, and accessories from one point of contact.
M83513
What Micro-D is
Micro-D is a microminiature rectangular connector whose contacts are arranged on .050 inch (1.27 mm) centers. The U.S. military specification MIL-DTL-83513 (M83513) defines the family, and Amphenol designs this product group as a miniature interconnect that goes beyond the specification's requirements.
Amphenol Canada does not stop at M83513 rectangular connectors — it develops and manufactures circular, stripline, and PCB connectors in the same family, along with hybrid connectors that mix power, signal, coaxial, and optical contacts.
The product families are divided by shell material. The metal-shell 100 series, the all-plastic 102 series, and the stainless 104 series share identical dimensions and mate with each other; beyond those there are the 105 strip, the 106 high-density card, and the M13 filter families.

Slash Sheets
Termination types, set by the slash sheet
In M83513 the slash number specifies the termination type. The number on the drawing alone pins down the form.
Termination type by slash sheet — with the Amphenol termination code6 rows · tap to expand
| Slash sheet | Termination | Amphenol termination code |
|---|---|---|
| /01 · /02 | Solder cup | — |
| /03 · /04 | Crimp (wire, harness) | — |
| /10 ~ /15 | Narrow 90° PCB | CBR |
| /16 ~ /21 | 90° PCB | BR |
| /22 ~ /27 | Straight PCB | BS |
| /28 ~ /33 | Straight PCB | C6 |
Within one termination the number splits again by pin (plug) or socket (receptacle) and by shell size — for solder cup, /01 is the plug and /02 the receptacle. The C16 configuration, which adds a flange to C6, is an Amphenol style outside the specification sheet.
The terminations ADMTEC has actually supplied are solder cup (/02), crimp wire (/03 · /04), narrow 90° PCB (/10 · /11), and straight PCB C6 (/29). Shell sizes 15 · 25 · 51 and shell finishes in electroless nickel and passivated stainless are in that record. The remaining sheets in the table are supplied on the same authorized basis.
Part Number
Breaking down an M83513 part number
The number written on the drawing is enough to confirm what is needed. The crimp-terminated M83513/04-G01N is used here as the example.

The paired codes 03 · 04 · 11 · 12 · 14 · 16 · 20 ~ 22 are the color-designated versions of the same wire. Length tolerance is +1.00 / −0.00 inch.
Shell material by series4 rows · tap to expand
| Series | Shell material |
|---|---|
| 100 · 106 · 110 · M13 | Aluminum alloy 6061-T6 (QQ-A-200/8) |
| 104 | Stainless steel |
| 101 · 102 · 105 | Polyphenylene sulfide (Ryton) |
| High-temperature versions | High-performance thermoplastics such as PEEK |
Metal shell finishes are chosen from anodize, cadmium, gold, iridite/alodine, electroless nickel, and tin (anodize and iridite are excluded on die cast parts). The insulator is PPS to MIL-M-24519 type GST-40F, and the hardware is passivated stainless.
Solder cup terminations carry no wire code, so they end as M83513/02-GN. In Amphenol's internal numbering these correspond to 100RN51S-4E1AB and 100RN51S-B respectively, and we will confirm the part from either number.

Whole-connector engagement force is specified as (10 oz × contact count) max and separation force as (0.5 oz × contact count) min. Values can differ on anything departing from the standard product, so it needs to be confirmed before use.
Contacts
Precision stamped and formed contacts
What separates one Micro-D from another comes down to the contact construction. Amphenol uses a precision stamped and formed design in this family.
One-piece contact with evenly spaced tinesDetails · tap to expand
The contact is formed from a single piece with its tines spaced evenly. Contact is made along a line running the length of the contact beam, which is a different form of contact from designs that touch at several separate points.
Gold over a nickel barrierDetails · tap to expand
A nickel barrier sits under the gold plating. Plating thickness is more uniform than with a copper flash barrier. The contacts are copper alloy with 50 μin of gold.
Uniform insertion forceDetails · tap to expand
The closed one-piece mating end keeps insertion force uniform, and the design keeps engagement and separation forces low. Socket contacts are precision-machined tubular type, and both pins and sockets are fixed with epoxy into a high-grade thermoplastic insulator.
Space and satellite useDetails · tap to expand
The catalog names this contact as the preferred contact for space and satellite applications. Thermal vacuum outgassing performance goes beyond the SP-R-0022 or ASTM E595 criteria (TML 1.0% · VCM 0.1%).
Accessories
Backshells, caps, and filters
These are ordered together with the connector.

Q&A
Frequently Asked Questions
My drawing only says M83513/04-G01N — what part is that?
A crimp (wire) terminated receptacle, 51 contacts, M22759/11 26 AWG wire at 18 inches, with an electroless nickel shell. /04 sets the termination type and the socket gender, G sets the contact count of 51, 01 sets the wire specification and length, and N sets the shell finish. Even a partial number is enough for us to confirm the rest.
Should I choose a metal shell or a plastic shell?
The metal-shell 100 series (aluminum 6061-T6), the stainless 104 series, and the all-plastic 102 series are designed to identical dimensions and mate with each other, so the shell material can be changed without changing the connector on the other side. Note that plastic shells do not include an interfacial seal — tell us if sealing is required.
Can it be used for space and satellite applications?
The catalog names this precision stamped and formed contact as the preferred contact for space and satellite applications, and specifies thermal vacuum outgassing beyond the SP-R-0022 or ASTM E595 criteria (TML 1.0% · VCM 0.1%). Space-grade M22759/33 wire can also be specified. Tell us the grade you need and we will point you to the matching P/N.
Do you supply EMI backshells and dust caps as well?
Yes. We handle MBS EMI backshells (sizes 9 to 100, straight and 90° exits, 60 dB or better shielding up to 1 GHz), MDCE dust caps, and connector savers. There is no need to source the connector and the accessories separately — we confirm them together.
I need an EMI filter — is there a matching part?
There is the M13 filter Micro-D family. These are sizes 9 to 37 with a Pi or C filter built in, supporting solder cup, PCB, and wire terminations, and they mate with standard M83513 connectors. Tell us the insertion loss and frequency band you need and we will confirm the filter circuit.
Why is size 69 marked differently from the other sizes?
9 · 15 · 21 · 25 · 31 · 37 · 51 · 100 are M83513 specification arrangements, but 69 alone is non-military. If the drawing requires compliance with the military specification, this has to be confirmed before proceeding.
Can I get a C of C with the order?
Yes. We issue one for every order — what it covers and the original certificate are on the Authorized Distributor certification page.
