71-433036-28S

Overview

The Amphenol Aerospace Operations model 71-433036-28S is a circular MIL-DTL-38999 Series I connector. It features a receptacle configuration with female socket contacts. The unit utilizes a crimp termination method for reliable electrical connections. The housing is constructed from aluminum alloy and finished with non-electrolytic nickel plating to ensure corrosion resistance. This component is designed for free-hanging installation within complex wiring assemblies.

Feature Summary

• Provides secure signal transmission through female socket contact interfaces
• Ensures environmental protection against moisture and contaminants
• Facilitates rapid assembly via standardized crimp termination processes

Applications

• Avionics systems in commercial and military aircraft
• Flight control instrumentation circuits
• Military ground combat vehicle electrical networks
• Aerospace engine monitoring and control units

Procurement Notes

Verify the specific shell size and contact arrangement against engineering drawings before ordering. Confirm that the crimp tooling matches the required contact type. Ensure compliance with project-specific environmental sealing requirements. Check for any mandatory quality assurance certifications required by the end-user. Validate compatibility with mating plug connectors to prevent interface mismatches during integration.

Selection Notes

Select this component when a robust, shielded circular connector is required for harsh environments. Consider the aluminum housing weight benefits compared to steel alternatives. Evaluate the need for specific contact current ratings relative to the circuit load. Assess the operating temperature range requirements against the standard specifications. Determine if the free-hanging mounting style fits the available chassis space.

Part Context

This part belongs to the MIL-DTL-38999 Series I family of circular connectors. It represents a standard industrial-grade interconnect solution widely used across defense and aerospace sectors. The series offers various shell sizes and contact configurations to suit diverse pin counts. It serves as a foundational component for building reliable cable assemblies and panel-mounted interfaces.

Replacement Considerations

Compatible equivalents include parts adhering to the same MIL-DTL-38999 Series I mechanical and electrical standards. Verify cross-reference numbers such as 71-433036-28S variants from other qualified manufacturers. Ensure dimensional interchangeability for panel cutouts and mating flanges. Confirm identical contact gender and shell finish specifications for direct substitution.
