WTAX70SACJTC

Overview

The WTAX70SACJTC is a rectangular MIL-DTL-55302 qualified connector from the AirBorn W Series, manufactured by Molex. It functions as a free-hanging panel receptacle with 70 positions arranged in two rows. The component utilizes solder cup termination for wire attachment and features gold-plated copper alloy socket contacts. Designed for board mounting applications, it operates within a temperature range of -65°C to +125°C. The housing is constructed from Polyphenylene Sulfide (PPS), providing robust insulation and mechanical stability for high-reliability military and aerospace environments.

Feature Summary

• MIL-DTL-55302 qualified construction ensuring compliance with stringent military reliability standards
• Dual-row configuration supporting high-density interconnect requirements
• Gold-plated copper alloy socket contacts for durable signal transmission
• Polyphenylene Sulfide (PPS) housing material offering thermal and chemical resistance

Applications

• Military avionics systems requiring certified interconnects
• Aerospace ground support equipment
• High-reliability industrial control panels
• Defense communication hardware

Procurement Notes

Verify the specific datasheet revision and RoHS status directly with Molex/AirBorn before procurement. Confirm that the solder cup orientation matches your assembly requirements. Ensure compatibility with mating plugs from the same W Series family. Check for any specific handling instructions regarding the gold plating during installation.

Selection Notes

Select this model when a 70-position, dual-row MIL-DTL-55302 receptacle is required. It is suitable for applications needing solder cup termination rather than PCB pin headers. Consider the PPS housing material for environments with elevated temperatures up to 125°C. Verify that the panel cutout dimensions align with the free-hanging style specifications.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for mission-critical applications. The series is known for its high density and reliability in harsh environments. The WTAX70SACJTC specifically addresses needs for larger contact counts while maintaining the compact footprint characteristic of the W Series architecture.

Replacement Considerations

Direct substitutes may include other manufacturers' MIL-DTL-55302 compliant 70-position receptacles. Verify dimensional compatibility and contact arrangement before substitution. Cross-reference part numbers such as those from Amphenol or ITT Cannon if equivalent military specifications are required.
