WTB24SAD7J

Overview

The WTB24SAD7J is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a board mount receptacle featuring 24 positions arranged in a dual row configuration with socket contacts. The component utilizes through-hole termination and operates at a 2.54 mm pitch. Designed for vertical installation, it incorporates gold-plated copper alloy contacts within a polyphenylene sulfide (PPS) body. The unit supports a current rating of 5 A and maintains an insulation resistance of 5 GOhms across an operating temperature range of -65 C to +125 C.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Vertical orientation facilitates dense board mounting layouts
• Gold-plated copper alloy contacts ensure stable signal transmission

Applications

• Military avionics systems
• Ruggedized communication equipment
• Defense electronics assemblies

Procurement Notes

Verify the specific suffix against official datasheets to confirm tail length and jackset variations. Confirm RoHS compliance status directly with the manufacturer. Ensure the procurement channel provides traceability documentation required for military-grade components. Validate that the received part matches the exact ordering code regarding contact plating and housing material specifications.

Selection Notes

Select this variant when a vertical mounting profile is required for space-constrained designs. The 2.54 mm pitch accommodates standard PCB spacing requirements. Verify that the 5 A current rating meets the circuit load demands. Consider the PPS housing material for thermal stability during soldering processes. Ensure the through-hole footprint aligns with the target PCB layout constraints.

Part Context

This component belongs to the AirBorn W Series, a family of high-density rectangular connectors designed for demanding environments. The series offers various configurations including right-angle and straight orientations. These connectors are engineered to withstand harsh conditions while maintaining electrical integrity in critical applications.

Replacement Considerations

Cross-reference with WTB24SOR9J for right-angle alternatives. Verify compatibility with WTB24SAD9JTA if different tail lengths or jacksets are needed. Ensure substitute parts maintain identical MIL-DTL-55302 compliance and pinout configurations.
