WTB54SAD11SY-1

Overview

The AirBorn WTB54SAD11SY-1 is a rectangular MIL-DTL-55302 board mount receptacle from the W Series. It features 54 positions arranged in two rows with a 2.54 mm pitch. The connector utilizes socket contacts made of copper alloy with gold plating, terminated via through-hole soldering. Constructed with a Polyphenylene Sulfide (PPS) body, it supports a current rating of 5 A and a voltage rating of 1 kV. Operating temperatures range from -65 C to +125 C, with an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated copper alloy socket contacts for durable signal transmission
• Utilizes Polyphenylene Sulfide housing for high thermal stability

Applications

• Military avionics systems requiring standardized interconnects
• Ruggedized electronic enclosures operating in extreme temperatures
• High-density circuit board mounting applications

Procurement Notes

Verify the specific suffix '-1' against official Molex/AirBorn documentation to confirm polarization and guide set configurations. Ensure compatibility with mating plugs by checking pin/socket orientation standards. Confirm RoHS compliance status directly with the manufacturer as regulatory requirements may vary by production batch.

Selection Notes

Select this component when a dual-row, straight-mount receptacle with 54 circuits is required. Verify that the 2.54 mm pitch aligns with the PCB layout. Ensure the system environment stays within the specified -65 C to +125 C temperature range. Confirm that the 5 A current rating per contact meets the design load requirements.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The series offers various contact counts and termination styles. The WTB variant specifically denotes a board mount receptacle configuration within this family.

Replacement Considerations

The equivalent MIL specification part number is M55302/58-C54Y. Verify mechanical dimensions and contact alignment before substitution.
