WTB70SAD9SY-B82-4

Overview

The WTB70SAD9SY-B82-4 is a rectangular MIL-DTL-55302 series receptacle manufactured by Molex / AirBorn. It features a dual-row configuration with 70 positions and a 2.54 mm pitch. The component utilizes through-hole termination for socket contacts plated with gold. Constructed with a Polyphenylene Sulfide (PPS) body, it supports a current rating of 5 A and a voltage rating of 1 kV. The operating temperature range spans from -65 C to +125 C, with an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Includes B82 termination face sealing against conformal coating
• Features guide sets and mounting ears for secure board installation

Applications

• Military avionics systems requiring high-density interconnects
• Ruggedized electronic enclosures subject to environmental stress
• Defense communication equipment utilizing conformal coating processes

Procurement Notes

Verify the specific suffix designation during procurement to ensure the inclusion of the B82 conformal coating seal feature. Confirm that the ordering part number matches the required termination style and contact count. Cross-reference the manufacturer datasheet to validate compatibility with mating plugs within the same W Series family. Ensure compliance with relevant military standards for the intended deployment environment.

Selection Notes

Select this component when a straight, dual-row receptacle with 70 circuits is required for board mount applications. The choice is driven by the need for MIL-DTL-55302 compliance and specific sealing requirements provided by the B82 suffix. Consider the PPS housing material and gold-plated copper alloy contacts for durability in harsh conditions.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series offers various configurations including plugs and receptacles with different row counts and termination styles. The WTB70SAD9SY-B82 variant specifically denotes a 70-position straight receptacle with through-hole contacts and specialized sealing.

Replacement Considerations

Equivalent parts include other MIL-DTL-55302 compliant receptacles with matching pin counts and pitches. Verify mechanical dimensions and mating interface compatibility before substitution. Alternative suffixes may offer different sealing or termination options but must maintain the core electrical specifications.
