WTB50SOR7SY

Overview

The WTB50SOR7SY is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a board mount receptacle featuring 50 positions arranged in two rows with a 2.54 mm (0.100 inch) pitch. The component utilizes socket contacts with gold plating and a polyphenylene sulfide (PPS) plastic body. Designed for through-hole termination, it operates within a temperature range of -65°C to +125°C and supports a current rating of 5 A per contact.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability applications
• Features gold-plated copper alloy socket contacts for stable signal transmission
• Constructed with a durable polyphenylene sulfide (PPS) insulating body

Applications

• Military avionics systems requiring rugged interconnects
• Aerospace electronic equipment interfaces
• High-density board-to-board connections in defense electronics

Procurement Notes

Verify the specific suffix against official Molex / AirBorn documentation to confirm exact mechanical variations such as mounting ears or guide sets. Ensure compatibility with mating plugs regarding contact gender and orientation. Confirm environmental ratings and RoHS compliance status directly with the manufacturer prior to procurement.

Selection Notes

Select this component when a 50-position, dual-row receptacle with a 2.54 mm pitch is required for MIL-DTL-55302 compliant designs. Consider the through-hole termination method and vertical orientation. Evaluate thermal limits and current derating requirements against system specifications before integration.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors designed for demanding environments. The series offers various configurations including plugs and receptacles with different row counts and termination styles, all adhering to strict military standards for durability and performance.

Replacement Considerations

Direct substitutes must match the 50-position count, 2.54 mm pitch, and MIL-DTL-55302 specification. Verify identical contact type (socket), termination method (through-hole), and housing material. Cross-reference with other manufacturers' equivalent MIL-spec lines only if form, fit, and function are fully validated.
