WTKA44SSY-7

Overview

The WTKA44SSY-7 is a rectangular MIL Spec connector receptacle from the AirBorn W Series. It features 44 positions arranged in two rows with a 2.54 mm pitch. The component utilizes crimp termination for 22 AWG wires and mounts directly to PCBs at a straight angle. Contacts are gold-plated copper alloy sockets rated for 5 A current. The housing is constructed from Polyphenylene Sulfide (PPS), supporting an operating temperature range of -65 C to +125 C and offering 5 GOhms insulation resistance.

Feature Summary

• Military-grade rectangular interconnection solution designed for high-reliability environments
• Gold-plated copper alloy contacts ensure stable signal transmission and corrosion resistance
• Polyphenylene Sulfide housing provides thermal stability across extreme operational temperatures

Applications

• Defense systems requiring ruggedized interconnects
• Avionics equipment needing reliable signal routing
• Industrial control panels utilizing MIL-spec standards

Procurement Notes

Verify specific suffix requirements against official datasheets before ordering, as variations may exist within the W Series family. Confirm compatibility with mating plugs and panel cutouts. Ensure supply chain sources provide authentic components with traceable documentation. Check for RoHS compliance status if required by project specifications. Validate that the manufacturer accepts factory special orders for this configuration.

Selection Notes

Select this part when a 44-position straight-mount receptacle is required for military or industrial applications. The 2.54 mm pitch suits standard wire gauges like 22 AWG. Consider the PPS material for high-temperature resilience. Verify that the crimp termination method aligns with available assembly tooling. Ensure the 5 A rating meets circuit load requirements.

Part Context

This component belongs to the AirBorn W Series, a line of high-performance connectors known for durability in harsh conditions. The series supports various configurations for defense, aerospace, and medical markets. The WTKA44SSY-7 specifically addresses needs for dense, reliable connections in space-constrained electronic assemblies requiring strict environmental tolerance.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Generic equivalents may not match MIL-spec mechanical or electrical tolerances. Ensure any replacement maintains the same pin count, pitch, and mounting style.
