MIL-DTL-83503 (M83503) Rectangular Connectors
The MIL-DTL-83503 (M83503) specification covers the requirements for multi-contact, rectangular electrical
connectors terminating flexible flat cable, and for mounting on printed circuit board (PCB). There are three types
of these connectors: insulation displacement connectors, solder transition connectors, and header style
connectors. These are non-environmental connectors, and only plug-in component contacts with similar finishes
to the mating socket contacts should be mated.
The MIL-DTL-83503 insulation displacement connectors are used with insulated cable. When using insulation
displacement connectors, it is not necessary to strip the cable of insulation because the connector has a built in
blade or blades that will cut through the insulation and create a cold-weld, gas-tight connection to the conductor
which insures the connectors maximum performance and reliability.
A.E. Petsche carries several varieties of MIL-DTL-83503 rectangular connectors. Some of the features included in
this family of connectors are:
- Polarizing feature solderless wrappost or PWB termination
- Straight or right angle design
- Non-environmental three or four wall header
For more information on which M83503 connector is appropriate for your application, call A.E. Petsche at 844-
237-7600 to speak with one of our qualified experts.
Note: MIL-C-83503 has been replaced by MIL-DTL-83503.
