WTB90SAD7SY

Overview

The WTB90SAD7SY is a rectangular MIL-DTL-55302 series board mount receptacle manufactured by Molex / AirBorn. It features 90 positions arranged in two rows with a 2.54 mm (0.100 inch) pitch. The component utilizes gold-plated copper alloy socket contacts and a polyphenylene sulfide (PPS) plastic body. Designed for through-hole vertical mounting, it supports a current rating of 5 A and operates within a temperature range of -65°C to +125°C. The unit provides an insulation resistance of 5 GOhms and a voltage rating of 1 kV.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated copper alloy female contacts for corrosion resistance
• Constructed with high-temperature polyphenylene sulfide housing material

Applications

• Military avionics systems requiring verified interconnects
• Ruggedized electronic equipment operating in extreme temperatures
• High-density circuit board mounting applications

Procurement Notes

Verify the specific manufacturer source, as Molex acquired AirBorn. Confirm that the part number matches the exact MIL-DTL-55302 specification requirements for your design. Ensure compatibility with mating plugs from the same series. Check for any RoHS compliance documentation if required by your project standards. Validate that the 90-position configuration fits your PCB layout constraints.

Selection Notes

Select this component when a high-density, dual-row receptacle is required for MIL-Spec environments. The 2.54 mm pitch allows for standard spacing while accommodating 90 circuits. Consider the PPS material properties for thermal stability. Ensure the through-hole termination method aligns with your assembly process. Verify that the 5 A current rating meets the electrical load requirements of the application.

Part Context

This part belongs to the AirBorn W Series, which offers various configurations including straight and right-angle options. The WTB prefix indicates a two-row, straight receptacle with mounting ears. This series is widely used in defense and aerospace sectors due to its durability and standardized interface dimensions.

Replacement Considerations

Equivalent parts may include those designated under the alias M55302/60-B90X. Verify pinout and mechanical dimensions before substitution. Ensure mating connectors share the same contact type and pitch specifications.
