WTA66SACJ

Overview

The AirBorn WTA66SACJ is a rectangular board connector from the W Series, designed for high-density interconnect applications. It features 66 contacts arranged in two rows with a 2.54 mm pitch. The receptacle utilizes female socket contacts and employs a solder cup termination method for secure PCB mounting. Constructed with a Polyphenylene Sulfide (PPS) housing and gold-plated copper alloy contacts, it supports a current rating of 5 A and operates within a temperature range of -65°C to +125°C.

Feature Summary

• Military-grade construction compliant with MIL-DTL-55302 standards for rugged environments
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Polyphenylene Sulfide (PPS) housing provides thermal stability and mechanical durability

Applications

• Avionics systems requiring MIL-Spec reliability
• Ruggedized military communication equipment
• High-density electronic control units

Procurement Notes

Verify the specific suffix against official Molex/AirBorn documentation to confirm exact contact configuration and plating thickness. Ensure compatibility with mating plugs regarding orientation and hardware requirements. Cross-reference the manufacturer part number with equivalent MIL-DTL-55302 designations to avoid specification mismatches during sourcing.

Selection Notes

Select this component when a straight-mount receptacle with solder cup terminations is required for 66-channel interfaces. Confirm that the 2.54 mm pitch aligns with the target PCB layout. Validate that the operating environment falls within the specified temperature limits and that the 5 A current rating meets circuit demands.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors widely used in aerospace and defense sectors.
