WTAX26SACJTB

Overview

The WTAX26SACJTB is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It is a board mount receptacle featuring 26 positions arranged in two rows with a 2.54 mm pitch. The component utilizes solder cup termination for copper alloy contacts with gold plating. Constructed with a Polyphenylene Sulfide (PPS) housing, it supports a current rating of 5 A and a voltage rating of 1 kV. The unit operates within a temperature range of -65 °C to +125 °C and offers an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for high-reliability interconnects.
• Features removable socket contacts for simplified maintenance and replacement.
• Utilizes a hex turning jackset mechanism for secure panel or board mounting.
• Constructed with durable Polyphenylene Sulfide (PPS) housing material.

Applications

• Military avionics systems requiring ruggedized interconnects
• Ground-based defense communication equipment
• Aerospace electronic control units
• Harsh environment industrial instrumentation

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to confirm exact mechanical variations such as jackset dimensions or contact orientation. Ensure compatibility with mating plugs regarding pin/socket configuration and mounting ear absence. Cross-reference the MIL-DTL-55302 designation to validate regulatory compliance for defense applications before finalizing procurement orders.

Selection Notes

Select this model when a straight, board-mount receptacle with solder cup termination is required. Confirm that the 26-position count and 2-row layout match the circuit density needs. Verify that the operating temperature range and voltage ratings align with system electrical requirements. Ensure the absence of mounting ears fits the available chassis or PCB space constraints.

Part Context

This component belongs to the AirBorn W Series, a family of rectangular connectors designed for demanding environments. The series provides various position counts and termination styles while maintaining strict adherence to military standards. The WTAX26SACJTB specifically addresses applications needing robust, high-density connections with reliable solder cup interfaces.

Replacement Considerations

The part number alias M55302/58-A26H serves as a confirmed substitute identifier. Verify mechanical fit and electrical continuity with original system designs when utilizing this equivalent designation.
