WTKA20SSY

Overview

The WTKA20SSY is a rectangular military specification connector from the AirBorn W Series, manufactured by Molex. It is designed as a straight receptacle with input/output capabilities. The component features a two-row configuration with twenty positions and utilizes crimp termination for contacts. Constructed with gold-plated copper alloy contacts and a polyphenylene sulfide (PPS) housing, it supports a current rating of 5 A and operates within a temperature range of -65 °C to +125 °C. The unit adheres to MIL-DTL-55302 standards and maintains a 2.54 mm contact pitch.

Feature Summary

• Military-grade construction compliant with MIL-DTL-55302 specifications
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Polyphenylene sulfide housing provides thermal stability and durability

Applications

• Avionics systems requiring high-reliability interconnects
• Radar equipment signal routing
• Defense communication hardware integration

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to confirm exact contact plating thickness and housing material variants. Ensure compatibility with mating plugs regarding keying options and mounting style. Cross-reference the MIL-DTL-55302 designation to confirm compliance with current environmental testing requirements before finalizing procurement orders.

Selection Notes

Select this component when a straight, board-mountable or panel-mountable receptacle is required for high-density applications. The 2.54 mm pitch allows for compact circuit board layouts. Verify that the crimp termination method aligns with available assembly tooling and wire gauge specifications. Confirm that the operating temperature range meets the environmental demands of the target installation site.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors known for rugged performance in harsh environments. The series offers various configurations including cable and board mount options. The WTKA20SSY specifically addresses needs for secure, high-cycle life connections in defense and aerospace sectors where standard commercial connectors may fail under stress.

Replacement Considerations

Equivalent parts include those designated under MIL-DTL-55302 standards. Verify pinout compatibility and mechanical dimensions before substitution. Contact the manufacturer for updated cross-reference lists.
