71-433033-08Z

Overview

The Amphenol Aerospace Operations 71-433033-08Z is a circular MIL-spec receptacle conforming to MIL-DTL-38999 Series II standards. It features an aluminum alloy shell with olive drab cadmium plating and utilizes a bayonet coupling mechanism for secure attachment. The connector provides eight positions arranged in the 12-08 insertion pattern, housing female socket contacts that are gold-plated for reliable signal transmission. Designed for box mounting, it employs a crimp termination method for wire connections. This component is engineered for high-reliability interconnect applications within harsh environmental conditions typical of aerospace and defense systems.

Feature Summary

• Bayonet coupling system ensures rapid and secure mating cycles
• Gold-plated socket contacts provide corrosion resistance and low contact impedance
• Aluminum alloy housing offers structural durability in demanding environments

Applications

• Avionics systems requiring MIL-DTL-38999 compliance
• Defense communication equipment interfaces
• Radar system signal distribution panels

Procurement Notes

Verify the specific manufacturer source and authenticity when sourcing this part, as multiple entities may produce compatible variants under the same military specification. Confirm that the received unit matches the exact shell size, contact arrangement, and plating specifications required by your design. Ensure compatibility with corresponding plugs regarding coupling nut style and interface dimensions before final integration into the assembly.

Selection Notes

Select this receptacle when a box-mount configuration is required for MIL-DTL-38999 Series II applications. The choice depends on the need for a bayonet lock mechanism and the availability of eight socket positions in the 12-08 layout. Consider the aluminum construction and cadmium plating if operating in corrosive environments where weight savings relative to steel are necessary but extreme conductivity is not the primary constraint.

Part Context

This component belongs to the extensive family of circular connectors defined by MIL-DTL-38999, a standard widely adopted across the global defense and aerospace industries. Amphenol Aerospace Operations manufactures these connectors to meet rigorous military reliability requirements. The 71-series designation typically aligns with specific shell styles and mounting configurations within the broader 38999 ecosystem, ensuring interchangeability with other qualified manufacturers' products.

Replacement Considerations

Equivalent parts include MS27499E12B8SD and 88-443033-08Z, which share identical MIL-DTL-38999 specifications and physical dimensions. Verify cross-manufacturer compatibility regarding contact retention forces and interface tolerances before substitution.
