WTBT56SAR9SY

Overview

The WTBT56SAR9SY is a rectangular board connector from the AirBorn W Series, designed for high-reliability applications. It features 56 contacts arranged in two rows with a 0.1-inch (2.54 mm) pitch. The receptacle utilizes female socket contacts made of copper alloy with gold plating. Constructed with a glass-filled polyphenylene sulfide insulator, it supports through-hole solder termination and right-angle mounting. The component offers an insulation resistance of 5 GOhms and operates within a temperature range of -65°C to +125°C.

Feature Summary

• Right-angle board mount configuration with locking installation options
• Gold-plated copper alloy socket contacts for reliable signal transmission
• Glass-filled polyphenylene sulfide body for thermal stability

Applications

• Military and aerospace electronic systems
• High-density board-to-board interconnects
• Ruggedized industrial control equipment

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure correct polarization, guide set inclusion, and mounting ear configurations. Confirm that the right-angle orientation and locking mechanism align with the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this part when a right-angle receptacle with 56 positions is required. Ensure mating plugs are compatible with the 0.1-inch pitch and female contact gender. Verify that the operating environment stays within the specified -65°C to +125°C range and that the PPS material properties meet chemical resistance needs.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular MIL-Spec connectors known for durability. The series offers various contact counts and orientations, serving as a standard interface solution for demanding environments where vibration resistance and long-term reliability are critical design factors.

Replacement Considerations

Cross-reference with M55302/58-series equivalents if military specification compliance is mandatory. Verify physical dimensions and pinout compatibility with existing mating hardware before substitution.
