71-477108-35S

Overview

The Amphenol Aerospace Operations 71-477108-35S is a circular MIL-spec connector plug. It features 37 positions with male pin contacts. The shell size is 15, and it utilizes a bayonet coupling style for secure engagement. This component is designed for solder termination and panel mount installation. It adheres to the MIL-DTL-38999 Series I standard. The housing material is carbon steel with tin plating. Contact surfaces are gold-plated copper alloy. The assembly is straight and intended for harsh environment applications requiring reliable signal transmission.

Feature Summary

• Bayonet coupling mechanism ensures rapid and secure connection engagement
• Carbon steel shell provides structural durability in demanding environments
• Gold-plated contacts maintain low contact resistance and corrosion resistance
• Panel mount design facilitates fixed installation on equipment enclosures

Applications

• Avionics systems in military aircraft
• Radar and communication equipment interfaces
• Test and measurement instrumentation panels
• Industrial control system interconnects

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact contact arrangement and environmental sealing ratings. Ensure compatibility with mating receptacles regarding shell size and coupling type. Confirm that the supplier provides traceability documentation required for aerospace and defense procurement standards. Check for any updated revision levels that may affect form or fit dimensions.

Selection Notes

Select this model when a high-density 37-position interface is required within a compact shell size 15 footprint. The bayonet lock is suitable for applications where frequent disconnects are not necessary but vibration resistance is critical. Consider the solder termination method for permanent panel mounting rather than cable attachment. Evaluate the operating temperature range against the specific environmental conditions of the deployment site.

Part Context

This part belongs to the Amphenol Hermetics series, which focuses on high-reliability circular connectors. The series is widely used in aerospace and defense sectors due to its compliance with stringent military specifications. The 71- prefix typically denotes Amphenol's proprietary variations of standard MIL-DTL-38999 designs, often offering enhanced performance or specific manufacturing origins compared to generic equivalents.

Replacement Considerations

Cross-reference with MS27471Y15D37P as a potential equivalent based on shared MIL-DTL-38999 Series I specifications and identical position count. Verify dimensional tolerances and mating interface details before substitution. Ensure that any replacement maintains the same bayonet coupling style and panel mount configuration.
