WTB120PR7SY

Overview

The WTB120PR7SY is a rectangular MIL Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a plug with 120 positions arranged in two rows. The component utilizes through-hole termination and features gold-plated copper alloy pin contacts. Designed for board mount installation, it operates at right angles. Key electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV. The housing is constructed from Polyphenylene Sulfide (PPS), providing an insulation resistance of 5 GOhms. It supports a temperature range from -65 C to +125 C with a contact pitch of 2.54 mm.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability interconnects.
• Features gold-plated copper alloy pin contacts for durable signal transmission.
• Utilizes Polyphenylene Sulfide (PPS) housing material for thermal stability.

Applications

• Military avionics systems requiring ruggedized interconnects
• High-density electronic assemblies needing 120-position connectivity
• Board-to-board connections in harsh environmental conditions

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to ensure correct orientation and termination style. Confirm that the MIL-DTL-55302 compliance matches project requirements. Check for RoHS status details if environmental regulations apply. Ensure compatibility with mating receptacles within the same W Series family. Validate lead times as these components may be subject to special order processing.

Selection Notes

Select this model when a 120-position right-angle plug is required for board mounting. Ensure the design accommodates the 2.54 mm pitch and dual-row configuration. Verify that the 5 A current rating per contact meets circuit demands. Consider the operating temperature range of -65 C to +125 C for environmental suitability. Confirm that the through-hole termination method aligns with the PCB fabrication capabilities.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding applications. The series offers various position counts and configurations. The WTB prefix indicates a specific plug variant within this ecosystem. These connectors are engineered for durability and consistent performance in critical systems.

Replacement Considerations

The part number alias M55302/59B120X serves as a direct equivalent reference. Ensure any substitute maintains the 120-position count and right-angle form factor. Verify that the replacement meets the same MIL-DTL-55302 standards. Confirm physical dimensions and pinout compatibility before integration.
