WTB50SAD9SY-4

Overview

The AirBorn WTB50SAD9SY-4 is a rectangular MIL-DTL-55302 series receptacle featuring 50 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 current rating of 5 A and 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 female contacts for stable signal transmission
• Constructed with high-performance Polyphenylene Sulfide (PPS) insulating material

Applications

• Military avionics systems requiring certified interconnects

Procurement Notes

Verify the specific polarization suffix against design requirements, as the requested model number differs from standard catalog listings. Confirm RoHS compliance status directly with Molex/AirBorn documentation. Ensure the ordering suffix matches the exact guide set or mounting ear configuration required for the application.

Selection Notes

Select this component when a straight-mount receptacle with 50 circuits is required. Verify that the 2.54 mm pitch aligns with PCB layout constraints. Ensure the mating plug corresponds to the correct gender and polarization code to guarantee proper mechanical engagement and electrical continuity.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series offers various position counts and mounting styles while maintaining strict adherence to military standards for durability and performance consistency across diverse industrial applications.

Replacement Considerations

Cross-reference with M55302/58-B50Y-4 equivalents. Verify pinout compatibility and physical dimensions before substitution.
