Procurement Notes

Verify the specific suffix B82-7 against official manufacturer documentation to confirm exact tail length and guide set configuration. Ensure compatibility with mating plugs within the same W Series family. Confirm RoHS compliance status via the latest datasheet before integration into regulated assemblies.

Selection Notes

Select this part for high-density interconnects requiring MIL-DTL-55302 durability. The 70-position count suits complex circuitry needs. Verify that the 5 A current rating meets system requirements. Ensure PCB layout accommodates the dual-row through-hole footprint and mounting ear clearance.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The series offers various contact counts and configurations. The WTB70SAD9SY-B82 variant specifically addresses high-pin-count applications requiring robust mechanical retention and electrical performance under extreme temperatures.

Replacement Considerations

Equivalent parts may include other manufacturers' MIL-DTL-55302 compliant receptacles with matching pin counts and dimensions. Cross-reference physical dimensions and contact arrangements carefully. Verify that alternative suppliers offer identical gold plating and PPS housing materials.
