WTB24SAD9JTB

Overview

The WTB24SAD9JTB is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It features a straight receptacle design with 24 positions arranged in two rows. The component utilizes through-hole termination for board mounting and incorporates gold-plated copper alloy socket contacts. Constructed with a Polyphenylene Sulfide (PPS) housing, it operates within a temperature range of -65°C to +125°C. Key electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV, with an insulation resistance of 5 GOhms.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated copper alloy socket contacts for durable connection
• Utilizes Polyphenylene Sulfide (PPS) housing material for thermal stability

Applications

• Avionics control systems
• Military communication equipment
• Ruggedized electronic assemblies

Procurement Notes

Verify the specific suffix JTB against official datasheets to confirm contact orientation and plating thickness. Ensure compatibility with mating plugs regarding MIL-DTL-55302 standards. Confirm RoHS compliance status as documentation may vary by production batch. Validate that the 24-position configuration matches the target PCB footprint requirements before procurement.

Selection Notes

Select this part for applications requiring high-density interconnects in harsh environments. The 2.54 mm pitch allows for standard board spacing. Consider the straight mounting style for direct panel or board integration. Verify that the 5 A current rating per contact meets the circuit load requirements. Ensure the operating temperature range covers the intended environmental conditions.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding industrial and defense applications. The series offers various position counts and termination styles. The WTB24SAD9JTB specifically provides a robust solution for connecting circuits where vibration resistance and electrical integrity are critical. It serves as a reliable interface between PCBs and mating hardware.

Replacement Considerations

The part number alias M55302/58-B24H represents the same MIL-DTL-55302 specification. Cross-reference with other W Series variants if pin count adjustments are needed. Ensure any substitute maintains the 2-row, 24-position layout and through-hole termination method.
