WTBT56SAR9JTB

Overview

The WTBT56SAR9JTB is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a receptacle with 56 positions arranged in two rows. The component utilizes socket contacts made of copper alloy with gold plating. Termination is achieved via through-hole soldering in a right-angle board mount configuration. The housing is constructed from polyphenylene sulfide (PPS). Electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV. Insulation resistance is specified at 5 GOhms. The operating temperature range spans from -65 C to +125 C. Contact pitch is 2.54 mm, compatible with 22 AWG wire.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for high-reliability applications.
• Features a locking mechanism integrated into the design for secure mating.
• Utilizes gold-plated copper alloy sockets to ensure reliable signal transmission.
• Constructed with PPS insulation material for thermal stability.

Applications

• Military avionics systems requiring rugged interconnects
• Ground-based defense communication equipment
• High-density circuit board mounting in harsh environments

Procurement Notes

Verify the specific suffix JTB against official Molex/AirBorn documentation to confirm exact termination tail length and mounting ear configurations. Ensure compatibility with corresponding plug counterparts within the W Series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement.

Selection Notes

Select this part for applications demanding MIL-DTL-55302 compliance and right-angle PCB integration. Verify that the 56-position density and 2.54 mm pitch align with the target board layout. Ensure mating connectors support the required 5 A current rating and 1 kV voltage isolation. Confirm environmental sealing requirements match the connector's inherent capabilities.

Part Context
