WTB70SAD9SY

Overview

The AirBorn WTB70SAD9SY is a rectangular MIL-DTL-55302 series receptacle featuring 70 positions in a dual-row configuration. It utilizes socket contacts with gold plating on copper alloy terminals, mounted vertically via through-hole termination. The housing is constructed from Polyphenylene Sulfide (PPS) with a 2.54 mm pitch and includes guide sets and mounting ears. Rated for 1 kV voltage and 5 A current, it operates between -65°C and +125°C with an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated copper alloy socket contacts for stable signal transmission
• Includes integrated guide sets and mounting ears for precise alignment and secure board attachment

Applications

• Military avionics systems requiring high-density interconnects
• Ruggedized electronic enclosures subject to harsh environmental conditions
• Industrial control panels demanding verified MIL-Spec connector performance

Procurement Notes

Verify the specific suffix B82 against official Molex/AirBorn documentation to confirm exact tail length and guide set inclusion. Ensure compatibility with mating plugs such as WTBV series components. Confirm RoHS status and lead times directly with authorized distributors, as availability varies by region and production cycle.

Selection Notes

Select this component when a straight, dual-row receptacle with 70 circuits is required for PCB mounting. Verify that the 2.54 mm pitch aligns with existing board layout constraints. Ensure the operating temperature range of -65°C to +125°C meets system thermal requirements. Confirm that the 1 kV rating is sufficient for the intended circuit voltage levels.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors designed for high-reliability applications. The series offers various position counts and termination styles, all adhering to strict military standards. The WTB70SAD9SY specifically addresses needs for high-density vertical board mounting with robust mechanical retention features.

Replacement Considerations

Equivalent parts include M55302/58-B70X. Verify pinout compatibility and physical dimensions before substitution. Cross-reference with other manufacturers' MIL-DTL-55302 compliant receptacles if sourcing flexibility is required.
