WTA40PCJTC

Overview

The WTA40PCJTC is a rectangular MIL-DTL-55302 series board mount receptacle manufactured by Molex / AirBorn. It features 40 positions arranged in two rows with a 2.54 mm pitch. The component utilizes female socket contacts made of copper alloy with gold plating, terminated via straight through-hole solder cup connections. Designed for vertical mounting on printed circuit boards, the housing is constructed from Polyphenylene Sulfide (PPS). It operates within a temperature range of -65°C to +125°C and supports a current rating of 5 A per contact.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for high-reliability interconnects
• Features gold-plated copper alloy socket contacts for corrosion resistance
• Utilizes durable Polyphenylene Sulfide (PPS) insulating material
• Supports standard through-hole solder cup termination methods

Applications

• Military avionics systems requiring ruggedized connectivity
• Aerospace ground support equipment interfaces
• High-reliability industrial control panel assemblies
• Defense communication hardware backplanes

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct termination length and contact orientation. Confirm RoHS compliance status as it varies by manufacturing batch. Cross-reference the full part number with the latest AirBorn datasheet to validate mating compatibility with corresponding plug connectors before procurement.

Selection Notes

Select this component when a 40-position dual-row receptacle is required for MIL-DTL-55302 applications. Ensure the design accommodates the 2.54 mm pitch and through-hole solder cup footprint. Verify that the operating environment remains within the specified -65°C to +125°C thermal limits and that the 5 A current rating meets circuit requirements.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors designed for demanding environments. The series offers various contact counts and termination options while maintaining strict adherence to military standards. The WTA designation specifically indicates a straight receptacle configuration without mounting ears.

Replacement Considerations

Compatible substitutes include other MIL-DTL-55302 Class K or L connectors with matching 40-position layouts. Verify pinout orientation and housing dimensions before substitution. Equivalent parts must maintain the same 2.54 mm pitch and through-hole termination style.
