WTA10SAD7J

Overview

The AirBorn WTA10SAD7J is a rectangular MIL-DTL-55302 series board mount receptacle featuring 10 circuits in a dual-row configuration. It utilizes socket contacts with gold plating on copper alloy substrates, designed for through-hole termination. The housing is constructed from polyphenylene sulfide (PPS) plastic with a fixed jackset and no mounting ears. Key electrical ratings include a 5 A current capacity and 1 kV voltage rating, alongside 5 GOhms insulation resistance. It operates within a temperature range of -65 C to +125 C and supports 22 AWG wire gauges at a 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated copper alloy socket contacts for stable signal transmission
• Constructed with high-temperature resistant PPS plastic housing
• Designed for vertical through-hole board mounting applications

Applications

• Military avionics systems requiring standardized interconnects
• Ruggedized electronic equipment operating in extreme temperatures
• Defense communication hardware interfaces
• Aerospace control panel connections

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to ensure correct contact orientation and housing variations. Confirm RoHS compliance status directly with the manufacturer as regulatory requirements may vary by production batch. Ensure compatibility with mating plug components before finalizing procurement orders.

Selection Notes

Select this component when a 10-position dual-row receptacle is required for MIL-DTL-55302 compliant designs. Consider the straight through-hole mounting style and fixed jackset design for PCB integration. Evaluate the 5 A current rating and 1 kV isolation against system power requirements. Verify that the 2.54 mm pitch aligns with existing board layout constraints.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors widely used in defense and aerospace sectors. The series offers various position counts and contact types, ensuring interchangeability with legacy MIL-C-5015 standards while providing modern manufacturing consistency. The WTA designation specifically identifies the receptacle variant within this ecosystem.

Replacement Considerations

Compatible substitutes include other W Series receptacles with matching pin counts, such as WTA14SAD7J or WTA20SAD7J, provided mechanical dimensions allow. Cross-reference mating plugs like WTAX10PCJT to ensure proper interface alignment. Always validate dimensional drawings against the original design specifications before substitution.
