WTB44SAD9SY-6

Overview

The AirBorn WTB44SAD9SY-6 is a rectangular MIL-DTL-55302 series receptacle featuring 44 positions in a dual-row configuration. It utilizes gold-plated copper alloy socket contacts with a 2.54 mm pitch and through-hole termination for board mounting. The housing is constructed from Polyphenylene Sulfide (PPS), supporting a 1 kV voltage rating, 5 A current capacity, and an insulation resistance of 5 GOhms. Operating temperatures range from -65°C to +125°C.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated copper alloy female contacts for stable signal transmission
• Constructed with high-performance PPS plastic housing for thermal stability

Applications

• Military avionics systems requiring certified interconnects
• Ruggedized electronic equipment operating in extreme environments
• High-density circuit board mounting applications

Procurement Notes

Verify the specific polarization code suffix against project requirements, as variants exist within the W Series. Confirm RoHS compliance status directly with Molex/AirBorn documentation prior to integration. Ensure the ordering part number matches the exact contact count and termination style needed for the PCB layout.

Selection Notes

Select this component when a dual-row, straight-mount receptacle is required for high-reliability circuits. The 2.54 mm pitch accommodates standard wire gauges, while the PPS body ensures durability under thermal stress. Verify that the 5 A per contact rating aligns with the system's electrical load demands.

Part Context

This connector belongs to the AirBorn W Series, a family of rectangular MIL-DTL-55302 connectors designed for demanding aerospace and defense applications. The series offers various position counts and polarization options to meet diverse interface needs while maintaining strict environmental sealing and mechanical integrity standards.

Replacement Considerations

The part is functionally equivalent to the government stock number M55302/58-B44Y-6. Cross-reference these identifiers to ensure compatibility with existing inventory or legacy system designs.
