WTDXA24SSY

Overview

The WTDXA24SSY is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It is a straight receptacle designed for I/O applications with 24 positions arranged in two rows. The component features solder cup termination and gold-plated copper alloy contacts. It operates within a temperature range of -65°C to +125°C and supports a current rating of 5 A per contact. The housing is constructed from polyphenylene sulfide (PPS), providing an insulation resistance of 5 GOhms and a voltage rating of 1 kV. The pitch is 2.54 mm.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged performance
• Utilizes gold-plated contacts on a copper alloy base for reliable conductivity
• Constructed with polyphenylene sulfide housing for thermal stability

Applications

• Military and aerospace electronic systems
• Ruggedized industrial equipment interfaces
• High-reliability board-to-board or cable connections

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Molex/AirBorn before procurement. Confirm that the solder cup orientation matches the assembly requirements. Ensure the ordering part number corresponds exactly to the straight receptacle configuration with the specified contact count and plating to avoid integration errors.

Selection Notes

Select this component when a MIL-DTL-55302 compliant straight receptacle is required for high-density interconnects. The 2.54 mm pitch suits standard wire gauges like 22 AWG. Consider the PPS material properties for environments requiring operation up to +125°C. Verify mating connector compatibility within the W Series family to ensure proper alignment and electrical continuity.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors known for high reliability in harsh environments. AirBorn, now part of Molex, specializes in military-grade interconnect solutions. The W Series typically offers various configurations including chassis and free-hanging options, with standardized pitches and robust contact arrangements for demanding applications.

Replacement Considerations

The part alias M55302/58-A20F indicates a potential cross-reference to MIL-DTL-55302 equivalents. Verify exact dimensional and electrical compatibility with any substitute parts. Ensure the replacement maintains the same row count, position quantity, and termination style.
