WTKA66SJTB

Overview

The AirBorn WTKA66SJTB is a rectangular MIL-DTL-55302 series connector designed for board mount applications. It features a straight receptacle configuration with 66 positions arranged in two rows. The component utilizes socket contacts with gold plating and a solder cup termination method. Constructed with a polyphenylene sulfide (PPS) housing, it supports a current rating of 5 A and a voltage rating of 333 V. The unit operates within a temperature range of -65 C to +125 C and maintains a contact pitch of 2.54 mm.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated beryllium copper socket contacts for corrosion resistance
• Utilizes polyphenylene sulfide housing material for thermal stability

Applications

• Military avionics systems
• Ruggedized electronic enclosures
• Defense communication equipment

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact contact orientation and mounting variations. Ensure compatibility with mating plug components from the same WTA series family. Confirm that the solder cup termination aligns with your PCB fabrication capabilities. Cross-reference the environmental ratings with your operational requirements before finalizing procurement orders.

Selection Notes

Select this model when a high-density 66-position interconnect is required in a compact two-row layout. The straight orientation suits vertical board mounting scenarios. Verify that the 2.54 mm pitch matches your existing footprint designs. Consider the PPS material properties if high-temperature soldering processes are involved in assembly.

Part Context

This component belongs to the AirBorn WTA series, which provides standardized rectangular connectors for demanding environments. The series offers various position counts and termination options while maintaining consistent mechanical interfaces. The WTKA variant specifically denotes a straight receptacle design intended for secure board-level integration in critical infrastructure.

Replacement Considerations

Direct substitutes must match the MIL-DTL-55302 standard and maintain identical pinout configurations. Verify that alternative parts support the same 66-position count and 2.54 mm pitch. Ensure mating compatibility with existing plugs in the system architecture.
