WTA70SACJ

Overview

The WTA70SACJ is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex / AirBorn. It features a straight receptacle design with 70 positions arranged in two rows. The component utilizes through-hole termination for board mounting and contains female socket contacts made of copper alloy with gold plating. Key electrical specifications include a current rating of 5 A, a voltage rating of 1 kV, and an insulation resistance of 5 GOhms. The connector operates within a temperature range of -65 C to +125 C, uses a 2.54 mm pitch, and supports 22 AWG wire gauge.

Feature Summary

• Complies with MIL-DTL-55302 military standards for high-reliability applications
• Constructed with Polyphenylene Sulfide (PPS) housing material
• Features gold-plated copper alloy contacts for corrosion resistance

Applications

• Military aerospace systems requiring rugged interconnects
• Avionics equipment demanding high-density connections
• Defense electronics operating in extreme environmental conditions

Procurement Notes

Verify the specific suffix codes against official Molex / AirBorn documentation to ensure exact configuration matching. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure compatibility with mating connectors within the same W Series family before procurement.

Selection Notes

Select this part for applications requiring a 70-position straight board-mount receptacle. Verify that the 2.54 mm pitch and through-hole termination method align with the PCB layout. Ensure the 5 A current rating and 1 kV voltage rating meet the system's electrical requirements.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular MIL-Spec connectors designed for mission-critical environments. The series offers various configurations to support high-density interconnect needs in defense and aerospace sectors, emphasizing durability and signal integrity under harsh conditions.

Replacement Considerations

Check for equivalents such as WTB70SACSY or WTAX70SAD9SYL, noting differences in termination type (solder cup vs. through-hole). Verify if alternative suffixes provide necessary environmental sealing or locking mechanisms not present in the base model.
