Comprehensive Engineering Specification & Standards Reference

1. General Description & Classification

The MIL-DTL-83513 specification covers polarized shell, microminiature rectangular electrical connectors with nonremovable contacts. Designed for high-density, high-reliability aerospace and military electronics, these connectors feature 0.050-inch (1.27 mm) contact spacing.

Connectors within the MIL-DTL-83513 standard are classified according to Shell Class and Termination Type:

Class M — Metal Shell: Features a metal shell with an internal plastic insulator. Available shell plating options include cadmium, electroless nickel, passivated stainless steel, pure electrodeposited aluminum, zinc nickel, and nickel fluorocarbon polymer.
Class P — Plastic Shell: Features an all-plastic shell and insulator assembly for weight-sensitive applications.
Type I — Crimp Contacts: Factory pre-wired crimp contact connectors with nonremovable contacts and epoxy potting.
Type II — Solder Contacts: Solder cup or printed circuit board (PCB) solder pin/socket termination configurations.

2. Technical, Mechanical & Environmental Characteristics

Current Rating: Maximum 3 amperes per contact.
Contact Spacing: 0.050 inch (1.27 mm) center-to-center contact spacing.
Operating Temperature Range: -55°C to +125°C.
Interfacial Sealing: Receptacle connectors feature an interfacial seal to protect against environmental degradation when mated.
Mating Hardware Torque: 2.5 inch-pounds maximum torque for #2-56 hardware (contact arrangements A through G: 9–51 contacts); 4.5 inch-pounds maximum torque for #4-40 hardware (arrangement H: 100 contacts).
Salt Spray Resistance: Finish options are tested to withstand a minimum 48-hour salt spray corrosion requirement.
Fungus Resistance: All constituent materials are required to be fungus inert.
Lead Termination Plating: PCB terminal solder leads are finished with tin-lead dipping (SN60/PB40 or SN63/PB37 per J-STD-006) with a minimum 3% lead content to prevent tin whisker growth.
