71-432481-11S

Overview

The Amphenol Aerospace Operations part number 71-432481-11S is a circular connector assembly classified under the MIL-DTL-38999 Series I standard. It functions as a receptacle with female socket contacts, designed for panel mount installation using a flange configuration. The housing is constructed from aluminum alloy and features a cadmium electroless nickel plating finish to ensure environmental durability. Electrical termination is achieved via solder connections for the contacts, which are made of copper alloy and plated with gold to maintain signal integrity. This component supports high-density interconnect applications requiring robust mechanical coupling and reliable performance in demanding operational conditions.

Feature Summary

• Panel-mount receptacle design with flange mounting characteristics for secure structural integration
• Copper alloy contacts terminated by solder method with gold plating for enhanced conductivity
• Aluminum housing with cadmium electroless nickel plating providing corrosion resistance
• Compliance with MIL-DTL-38999 Series I specifications for military-grade reliability

Applications

• Avionics systems in commercial and military aircraft
• Radar and communication equipment interfaces
• Test and measurement instrumentation panels
• Industrial control systems requiring rugged connectivity

Procurement Notes

Verify the specific shell size and contact arrangement against the official datasheet to ensure compatibility with mating plugs. Confirm that the solder termination type matches the PCB or cable harness requirements. Check for any superseded part numbers or alternate suffixes that may indicate minor manufacturing updates while maintaining functional equivalence. Ensure procurement channels provide traceability documentation required for aerospace and defense supply chains.

Selection Notes

Select this component when a shielded, high-density circular connector is needed for panel-mounted applications. Consider the MIL-DTL-38999 Series I form factor for interchangeability with other manufacturers' products adhering to the same standard. Evaluate the thermal and vibration environment to confirm the solder termination and aluminum housing are suitable. Compare pin-out configurations carefully to avoid mating errors with existing system infrastructure.

Part Context

This connector belongs to the extensive family of MIL-DTL-38999 Series I miniature cylindrical connectors produced by Amphenol Aerospace. These components are widely utilized across defense and aerospace sectors due to their standardized dimensions and high contact density options. The series represents a evolution from earlier MIL-C-26482 designs, offering improved shielding effectiveness and environmental sealing capabilities for modern electronic systems.

Replacement Considerations

Equivalent parts include those from ITT Cannon (e.g., CA3100E series) and LEMO (where applicable), provided they strictly adhere to MIL-DTL-38999 Series I dimensional and electrical standards. Verify that substitute components match the exact shell size, contact count, and orientation before implementation.
