71-418620-01P

Overview

The Amphenol Aerospace Operations part number 71-418620-01P is a circular MIL-spec connector plug. It features 1 position with pin contacts and utilizes a crimp termination method. The housing size is designated as 20, and the contact arrangement corresponds to position 1. This component is designed for cable mounting applications and operates within a temperature range of -55°C to +200°C.

Feature Summary

• Constructed with aluminum alloy housing featuring a non-electrolytic nickel finish.
• Equipped with gold-plated copper alloy contacts for reliable signal transmission.
• Designed for free-hanging or cable mounting installation styles.

Applications

• Commercial aerospace avionics systems
• Military aircraft power distribution
• Harsh environment instrumentation

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer before procurement. Confirm that the crimp tooling requirements match your existing assembly equipment. Ensure environmental sealing needs are met by the connector's inherent design or additional gaskets. Cross-reference the MIL-DTL-38999 series specifications to confirm interface compatibility with mating receptacles in your specific system architecture.

Selection Notes

Select this component when a single-position, high-reliability interconnect is required for aerospace applications. The aluminum housing provides necessary durability while managing weight constraints. Verify that the operating temperature range of -55°C to +200°C aligns with your system's thermal profile. Ensure the crimp termination type matches your wire gauge and strain relief requirements for secure electrical connections.

Part Context

This part belongs to the MIL-DTL-38999 Series I circular connector family produced by Amphenol Aerospace Operations. These connectors are widely used in defense and commercial aviation due to their compact size and high density. The 71-series designation typically indicates a specific shell style and coupling mechanism variant within the broader MIL-DTL-38999 standard framework.

Replacement Considerations

Direct substitutes include other manufacturers' MIL-DTL-38999 Series I plugs with identical shell size 20 and 1-position pin configurations. Verify dimensional interchangeability and mating face geometry before substitution. Equivalent parts from other qualified sources must meet the same environmental and electrical performance standards.
