STJ07RT-14-97SC

Overview

The STJ07RT-14-97SC is a circular MIL-spec connector receptacle manufactured by Amphenol Aerospace. It belongs to the 38999 Aluminum series and complies with MIL-DTL-38999 standards. The unit features a size 14 aluminum shell with nickel plating and a jam nut mounting style. It utilizes a bayonet coupling mechanism for secure connection. The insert arrangement is designated as 14-97, providing 12 positions. Contacts are female sockets made of copper with gold plating, designed for crimp termination. The component supports a voltage rating of 600 VAC and 850 VDC, with current ratings of 7.5 A and 13 A.

Feature Summary

• Constructed with an aluminum alloy shell featuring nickel electroplating for corrosion resistance and durability in harsh environments.
• Utilizes a bayonet-style locking mechanism to ensure rapid engagement and secure mating under vibration conditions.
• Incorporates gold-plated copper socket contacts terminated via crimping to maintain signal integrity and low contact resistance.
• Designed for panel-mount installation using a jam nut configuration, ensuring stable mechanical fixation.

Applications

• Avionics systems requiring MIL-DTL-38999 compliant interconnects
• Military ground equipment housing
• Radar and communication subsystems
• Test and measurement instrumentation

Procurement Notes

Verify the specific insertion arrangement code against engineering drawings to ensure pinout compatibility. Confirm that the crimp tooling matches the specified contact size. Check for any required accessory kits such as backshells or strain reliefs not included in the base part number. Ensure environmental sealing requirements align with the connector's inherent design capabilities.

Selection Notes

Select this model when a size 14 receptacle with 12 positions is required. Choose based on the need for a bayonet lock rather than threaded coupling. Consider the aluminum construction for weight-sensitive applications where steel alternatives are too heavy. Verify that the wall mount or panel mount orientation fits the chassis design constraints.

Part Context

This component is part of the extensive 38999 series family produced by Amphenol Aerospace. It shares common interface dimensions with other connectors in the series, allowing for mixed usage within compatible systems. The designation indicates a specific shell size and contact arrangement distinct from similar models like JT07RT or MS27467 variants.

Replacement Considerations

Cross-reference with part number 91-541079-97X for potential equivalent specifications. Verify dimensional compatibility before substituting with other manufacturers' offerings. Ensure that the replacement maintains the same MIL-DTL-38999 compliance level and electrical ratings.
