WTKA50SJ

Overview

The WTKA50SJ is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a plug configuration featuring 50 positions arranged in two rows with a 2.54 mm pitch. The component utilizes gold-plated copper alloy socket contacts and solder cup termination for board mounting. Rated for 5 A current and 1 kV voltage, it operates within a temperature range of -65 °C to +125 °C. The housing is constructed from Polyphenylene Sulfide (PPS), providing an insulation resistance of 5 GOhms.

Procurement Notes

Verify the specific suffix against official Molex / AirBorn documentation to confirm exact contact orientation and plating thickness. Ensure compatibility with mating receptacles within the same W Series family. Confirm RoHS status and environmental certifications required for the target deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a 50-position straight plug with solder cup termination is required. Verify that the 2-row layout fits the available PCB real estate. Ensure the mating counterpart matches the 2.54 mm pitch and contact gender. Consider the operating temperature range and voltage rating relative to the system's electrical requirements.

Part Context

This part belongs to the AirBorn W Series, a line of high-density rectangular connectors designed for demanding environments. The series offers various configurations including plugs and receptacles with different row counts and termination styles. The WTA/WTK variants typically denote specific plug configurations within this standardized military interconnect family.

Replacement Considerations

Cross-reference with M55302/55-A50H or equivalent MIL-DTL-55302 compliant parts. Verify dimensional tolerances and pin-out compatibility with existing mating hardware before substitution.
