71-482348-03P

Overview

The Amphenol Aerospace Operations part number 71-482348-03P is a circular MIL-spec connector receptacle. It complies with the MIL-DTL-26482 Series I standard and belongs to the D38999 III series. The component features a size 12 shell with a jam nut mounting style and straight orientation. It provides 3 positions utilizing pin (male) contacts. The termination method is solder, and the contact plating is gold over copper alloy. The housing is constructed from aluminum alloy with an olive drab cadmium finish.

Feature Summary

• Complies with MIL-DTL-26482 Series I specifications for rugged circular connectivity
• Features bayonet coupling mechanism for secure mating and unmating
• Utilizes gold-plated copper alloy contacts for reliable signal transmission
• Designed for panel mount installation via jam nut interface

Applications

• Avionics systems requiring MIL-DTL-26482 compliance
• Military communication equipment interfaces
• Ruggedized electronic enclosures needing secure circular connections

Procurement Notes

Verify the specific datasheet revision and environmental qualification status before procurement. Confirm that the jam nut mounting style and straight orientation match the mechanical constraints of the target enclosure. Ensure compatibility with the corresponding plug counterpart regarding shell size and contact arrangement. Check for any specific handling requirements associated with the gold plating and solder termination process during assembly.

Selection Notes

Select this component when a MIL-DTL-26482 Series I compliant circular connector is required for panel-mounted applications. The size 12 shell offers a compact form factor suitable for space-constrained environments. The gold plating on copper alloy contacts ensures low contact resistance and corrosion resistance. The jam nut style provides a secure mechanical attachment without requiring additional fasteners through the panel.

Part Context

This part belongs to the D38999 III family of circular connectors, which are widely used in aerospace and defense industries. The 71- prefix typically denotes Amphenol's manufacturing origin for these military-grade components. The series is characterized by high reliability and performance in harsh environments, including vibration and extreme temperatures.

Replacement Considerations

Cross-reference with other manufacturers offering MIL-DTL-26482 Series I connectors in size 12 with 3-pin configurations. Verify dimensional interchangeability, particularly the jam nut thread pitch and overall length. Ensure electrical characteristics such as current rating and insulation resistance meet or exceed original specifications.
