WTB90PR7SY

Overview

The AirBorn WTB90PR7SY is a rectangular MIL-DTL-55302 series connector featuring 90 positions in a dual-row configuration. It functions as a board-mount plug with pin contacts, utilizing through-hole termination and right-angle installation. The component employs gold-plated copper alloy contacts within a polyphenylene sulfide (PPS) housing. Electrical specifications include a 5 A current rating, 1 kV voltage rating, and 5 GOhms insulation resistance. It operates between -65°C and +125°C with a 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 military standards for high-reliability interconnects
• Right-angle board mount design facilitates dense circuit board layouts
• Gold-plated copper alloy contacts ensure stable signal transmission
• Polyphenylene sulfide housing provides thermal stability

Applications

• Avionics control systems
• Military communication equipment
• Radar and electronic warfare units
• Spacecraft instrumentation panels

Procurement Notes

Verify the specific suffix '7' indicates the correct polarization or guide set configuration required for your mating assembly. Confirm that the right-angle orientation matches your PCB mechanical constraints. Ensure the 90-position density aligns with your board space limitations. Cross-reference the MIL-DTL-55302 compliance requirements with your system's environmental qualification standards before finalizing procurement.

Selection Notes

Select this model when a high-density, right-angle male connector is required for board-to-board or board-to-chassis interfaces. The 90-position count suits applications needing extensive I/O in a compact footprint. The right-angle form factor aids in managing cable routing and reducing profile height. Verify compatibility with corresponding female receptacles from the same W Series family to ensure proper mating engagement.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for mission-critical environments. The series is characterized by its adherence to strict military specifications, offering robust performance in harsh conditions. The WTB variant specifically denotes a straight or angled plug configuration suitable for direct board mounting, distinguishing it from cable-mounted alternatives.

Replacement Considerations

Equivalent parts may include M55302/60-B90X or other MIL-DTL-55302 compliant 90-position right-angle plugs. Verify contact type, polarization, and mounting ear configurations before substitution.
