WTB70PR7SY-24

Overview

The WTB70PR7SY-24 is a rectangular MIL-spec connector from the AirBorn W Series, manufactured by Molex. It functions as a board mount plug with 70 positions arranged in two rows. The component utilizes through-hole termination for male pin contacts made of copper alloy with gold plating. Designed for vertical mounting on printed circuit boards, it features a Polyphenylene Sulfide (PPS) body and operates within a temperature range of -65°C to +125°C. The connector supports a current rating of 5 A per contact and a voltage rating of 1 kV, adhering to MIL-DTL-55302 standards.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability interconnects
• Features gold-plated copper alloy male pins for durable electrical connections
• Constructed with Polyphenylene Sulfide housing for thermal stability
• Supports through-hole mounting for secure PCB attachment

Applications

• Military aerospace avionics systems
• High-density backplane interconnections
• Ruggedized electronic equipment requiring MIL-Spec reliability

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to ensure correct configuration. Confirm that the specific revision matches project requirements. Check for authorized distribution channels to avoid counterfeit components. Validate compliance with relevant environmental regulations such as RoHS if applicable. Ensure compatibility with mating connectors in the assembly design.

Selection Notes

Select this component when a high-pin-count, MIL-Spec compliant header is required for board-to-board or cable-to-board applications. Consider the 2.54 mm pitch and 70-position capacity for space-constrained designs needing robust connectivity. Evaluate the through-hole mounting style against surface-mount alternatives based on mechanical stress requirements. Verify that the operating temperature range meets the environmental conditions of the intended deployment.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for mission-critical applications. The series offers various configurations including plugs and receptacles with different row counts and termination styles. The W Series is known for its high density and reliability in harsh environments, often used in defense and aerospace sectors where performance under extreme conditions is essential.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-55302 connectors from other manufacturers if supply constraints exist. Ensure dimensional compatibility and pinout alignment before substitution. Verify that alternative parts meet the same current, voltage, and temperature ratings. Consult official datasheets for mechanical drawings to confirm fitment.
