71-430582-41P

Overview

The Amphenol Aerospace Operations 71-430582-41P is a circular MIL-spec connector plug designed for high-reliability interconnect applications. It conforms to the MIL-DTL-38999 Series I standard, utilizing a Size 21 shell with a straight cable mount installation style. The component features a threaded coupling mechanism and is constructed from aluminum alloy housing with nickel plating. It supports up to 16 positions using crimp termination for contact attachment. The unit is rated for operation within a temperature range of -65°C to +200°C and provides environmental sealing capabilities suitable for demanding aerospace and military environments.

Feature Summary

• Conforms to MIL-DTL-38999 Series I specifications for standardized military interface compatibility
• Engineered with aluminum alloy housing and nickel plating for corrosion resistance and structural integrity
• Designed for cable mounting with a straight orientation to facilitate streamlined harness routing
• Utilizes crimp termination methods to ensure secure electrical connections for socket contacts

Applications

• Aerospace avionics systems requiring certified MIL-spec interconnects
• Military communication equipment operating in harsh environmental conditions
• Radar and navigation subsystems needing reliable signal transmission
• Ground support equipment and test instrumentation interfaces

Procurement Notes

Verify the specific contact configuration and pinout arrangement against the official datasheet before procurement, as variations exist within the same shell size. Confirm that the required socket contacts are sourced separately if not included in the assembly. Ensure compliance with the specified MIL-DTL-38999 Series I standards for your application's environmental requirements. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer to avoid supply chain disruptions during production.

Selection Notes

Select this model when a Size 21 shell is required for space-constrained installations while maintaining MIL-DTL-38999 Series I compatibility. Choose the threaded coupling style over bayonet types if higher vibration resistance and secure locking are prioritized over rapid mating cycles. Consider the aluminum construction for weight-sensitive applications where moderate corrosion protection via nickel plating is sufficient. Verify that the crimp termination method aligns with your available wire processing tools and quality control procedures.

Part Context

This component belongs to the extensive portfolio of circular connectors manufactured by Amphenol Aerospace Operations, a leading supplier of interconnect solutions for global defense and commercial markets. The 71-series designation typically indicates a specific shell style and coupling mechanism within the broader MIL-DTL-38999 family. These connectors are integral to modern electronic systems, providing robust connectivity in environments characterized by extreme temperatures, moisture, and mechanical stress.

Replacement Considerations

Cross-reference with other manufacturers' offerings that strictly adhere to MIL-DTL-38999 Series I dimensions and performance criteria. Verify interchangeability of mating interfaces, including thread pitch and engagement depth, to ensure seamless integration. Confirm that alternative sources meet the same material specifications and environmental sealing ratings. Consult official substitution guides from Amphenol for any direct equivalent part numbers within their own product line.
