WTBT10SAR9SY

Overview

The WTBT10SAR9SY is a rectangular MIL-DTL-55302 series receptacle manufactured by Molex / AirBorn. It features a dual-row configuration with 10 positions and a 2.54 mm (0.100 inch) contact pitch. Designed for board mount applications, it utilizes through-hole termination with socket contacts. The housing is constructed from Polyphenylene Sulfide (PPS) plastic with fixed jacksets and mounting ears. Rated for 5 A current and 1 kV voltage, it operates within a temperature range of -65 °C to +125 °C.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability interconnects
• Features right-angle orientation with through-hole solder termination for secure PCB mounting
• Utilizes gold-plated copper alloy contacts housed in durable PPS plastic bodies

Applications

• Military and aerospace electronic systems requiring ruggedized connectors
• Avionics equipment demanding high-density signal routing
• Defense communication hardware operating in extreme environmental conditions

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact mechanical variations such as tail length or jackset type. Ensure compatibility with mating plugs regarding contact gender and row alignment. Cross-reference the MIL-DTL-55302 designation to validate performance standards required for your specific deployment environment.

Selection Notes

Select this component when a right-angle, dual-row receptacle is required for space-constrained board layouts. Confirm that the 2.54 mm pitch aligns with your circuit design density needs. Verify that the through-hole termination method matches your manufacturing process capabilities and that the PPS material meets your thermal resistance requirements.
