STJ07RT-14-97S

Overview

The STJ07RT-14-97S is a circular MIL-spec receptacle connector manufactured by Amphenol Aerospace. It complies with MIL-DTL-38999 Series II standards and features a size 14 aluminum alloy shell with a jam nut mounting style. The connector provides 12 positions using socket contacts, which are crimp terminated and gold-plated on copper substrates. Rated for 600 VAC and 850 VDC, it supports current ratings of 7.5 A and 13 A. The assembly utilizes the 14-97 insertion arrangement and employs a bayonet coupling mechanism for secure panel installation.

Feature Summary

• Complies with MIL-DTL-38999 Series II specifications for rigorous environmental performance
• Features a lightweight aluminum alloy shell with a jam nut mounting style for secure panel installation
• Utilizes a three-point bayonet lock system for quick positive coupling and reliable engagement
• Incorporates five key/keyway designs to eliminate mismating and ensure error-proof alternate positioning

Applications

• Aerospace avionics systems requiring ruggedized interconnects
• Military communication equipment operating in harsh environments
• Ground-based electronic test and measurement instrumentation
• Naval shipboard control and monitoring subsystems

Procurement Notes

Verify that the specific suffix matches the required contact arrangement and termination type. Confirm compliance with the latest revision of MIL-DTL-38999 Series II. Ensure the jam nut mounting style aligns with the panel cutout requirements. Check for any special environmental sealing or shielding options if applicable to the mission profile.

Selection Notes

Select this component when a Series II MIL-DTL-38999 compliant receptacle is required. The size 14 shell accommodates 12 contacts suitable for moderate signal density. The aluminum construction offers weight savings compared to steel alternatives. Verify that the bayonet coupling speed meets operational cycle requirements.

Part Context

This part belongs to the JT series of subminiature cylindrical connectors developed for aerospace applications. The STJ prefix indicates a specific shell style and material configuration within the broader MIL-DTL-38999 family. These connectors supersede earlier MIL-C-38999 specifications while maintaining backward compatibility with established mating interfaces.

Replacement Considerations

Compatible substitutes include MS27484T14S97SB and other manufacturers' equivalents meeting MIL-DTL-38999 Series II standards. Verify dimensional interchangeability and electrical continuity before adoption.
