71-433337-35P

Overview

The Amphenol Aerospace Operations part number 71-433337-35P is a circular connector assembly belonging to the MIL-DTL-38999 Series I product line. This component functions as a receptacle with a jam nut mounting style and straight orientation. It features an aluminum shell with nickel plating and utilizes a bayonet coupling mechanism for secure engagement. The connector accommodates 23 positions using socket-type contacts, which are gold-plated for reliable conductivity. Termination is achieved through crimping methods, ensuring robust electrical connections within the specified military-grade specifications.

Feature Summary

• Constructed with a durable aluminum shell featuring nickel plating for environmental resistance
• Incorporates a bayonet coupling system for rapid and secure mating operations
• Designed with a jam nut installation style for fixed panel mounting applications

Applications

• Avionics systems requiring MIL-DTL-38999 compliance
• Military ground vehicle electrical interconnects
• Ruggedized electronic equipment housing

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct contact configuration and termination type. Confirm that the jam nut receptacle variant matches the intended panel thickness and mounting requirements. Cross-reference the 23-position socket arrangement with mating plug specifications to guarantee compatibility. Ensure all environmental ratings align with the operational temperature range defined in the datasheet.

Selection Notes

Select this component when a Series I circular connector with a jam nut interface is required. The aluminum construction offers a balance of weight and durability suitable for aerospace environments. Verify that the crimp termination method is compatible with the available wire gauge and contact size. Ensure the bayonet locking mechanism meets the vibration and shock resistance standards of the target application.

Part Context

This part belongs to the extensive family of MIL-DTL-38999 connectors produced by Amphenol Aerospace. These connectors are widely recognized for their high density and reliability in harsh environments. The Series I designation indicates a specific shell size and coupling style distinct from Series II or III variants. Understanding the broader series context helps in identifying compatible mating connectors and accessories within the same ecosystem.

Replacement Considerations

Public confirmed substitute part numbers include MS27468T17F99SA and 91-542705-99F. Verify dimensional compatibility and pinout alignment before substitution. Ensure that any replacement maintains the same MIL-DTL-38999 Series I certification and material specifications.
