M83513/25-C01NT

Overview

The M83513/25-C01NT is a D-Sub MIL-Spec connector from the AirBorn M Series, manufactured by Molex/AirBorn. It features a female receptacle configuration with 21 positions arranged in two staggered rows. The component utilizes through-hole termination for board mounting and operates at a straight installation angle. Contact surfaces are gold-plated to ensure reliable signal transmission. The housing size is designated as C, constructed from aluminum material with a cadmium finish for environmental protection. This connector complies with the MIL-DTL-83513 standard, providing a robust solution for high-density interconnect applications in demanding environments.

Feature Summary

• Compliant with MIL-DTL-83513 military specifications for rugged performance
• Gold-plated contacts ensure low resistance and corrosion resistance
• Aluminum housing provides structural integrity and shielding
• Staggered pin arrangement supports high-density circuit layouts

Applications

• Aerospace and defense avionics systems
• Military communication equipment
• Industrial control panels requiring MIL-spec reliability
• Ruggedized electronic enclosures

Procurement Notes

Verify the manufacturer designation carefully, as this part number may be fulfilled by Glenair or Molex/AirBorn depending on the specific supply chain channel. Confirm that the suffix 'NT' corresponds to the exact plating and housing requirements specified in the current datasheet. Ensure compatibility with mating connectors of the same MIL-DTL-83513 series before procurement to prevent interface mismatches.

Selection Notes

Select this component when a 21-position, two-row D-Sub connector is required for panel or board mounting. The choice is driven by the need for MIL-DTL-83513 compliance and gold-plated contacts. Consider the aluminum housing weight and thermal properties against plastic alternatives. Verify that the through-hole footprint matches the PCB design constraints and that the straight orientation fits the enclosure layout.

Part Context

This connector belongs to the M83513 family, which defines microminiature D-sub connectors for military use. AirBorn, now part of Molex, specializes in high-reliability interconnects for aerospace and defense sectors. The M Series offers various contact densities and termination styles, serving as a standard interface for critical electronic systems requiring durability and consistent electrical performance under harsh conditions.

Replacement Considerations

Cross-reference with other manufacturers producing MIL-DTL-83513 compliant parts, such as Glenair or Amphenol. Verify dimensional interchangeability, particularly the shell size C dimensions and pin spacing. Ensure that alternative sources provide equivalent gold plating thickness and cadmium coating specifications to maintain environmental resilience.
