WTB54SACSY

Overview

The AirBorn WTB54SACSY is a rectangular MIL-DTL-55302 series board mount receptacle connector. It features 54 positions arranged in two rows with a 2.54 mm (0.100 inch) contact pitch. The unit utilizes female socket contacts made of copper alloy with gold plating, housed in a polyphenylene sulfide (PPS) body. Designed for straight installation via solder cup termination, it supports a current rating of 5 A and operates within a temperature range of -65 °C to +125 °C.

Feature Summary

• MIL-DTL-55302 compliant military specification construction
• Gold-plated copper alloy socket contacts for reliable conductivity
• Polyphenylene sulfide housing material for thermal stability
• Straight board mount configuration with solder cup termination

Applications

• Avionics systems
• Radar equipment
• Military communication devices
• Aerospace instrumentation

Procurement Notes

Verify the specific suffix against official AirBorn documentation to confirm exact polarization, guide set presence, and mounting ear configurations. Ensure the procurement order matches the required MIL-DTL-55302 revision level and environmental ratings. Confirm compatibility with mating plug assemblies before finalizing orders.

Selection Notes

Select this component when a high-density 54-position interconnect is required for harsh environments. The 2.54 mm pitch suits standard PCB layouts, while the PPS body provides necessary heat resistance. Verify that the straight orientation and solder cup termination align with the target assembly manufacturing processes.

Part Context

This part belongs to the AirBorn W Series, a family of ruggedized rectangular connectors designed for demanding applications. The series offers various contact counts and termination styles, maintaining consistent mechanical interfaces across different pin configurations within the MIL-DTL-55302 framework.

Replacement Considerations

Direct replacements must adhere to the same MIL-DTL-55302 specifications. Cross-referencing requires matching the 54-position count, 2-row layout, and 2.54 mm pitch. Verify that alternative sources provide identical gold plating thickness and PPS housing properties.
