306-022-521-168

Overview

The EDAC Inc. 306-022-521-168 is a dual-edge female card edge connector from the 306 Series, designed for panel and through-hole mounting. It features 44 positions with a 0.156-inch (3.96mm) contact spacing arranged in two rows of seven contacts per side. The connector utilizes gold-plated cantilever contacts on a green thermoplastic polyester insulator. It accommodates PCB thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-edge female configuration with cantilever spring contacts for reliable board insertion
• Gold-plated terminals ensure stable electrical performance and corrosion resistance
• Thermoplastic polyester insulation provides structural integrity across specified temperatures
• Panel mount design with flush flange and threaded inserts for secure installation

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit boards
• Energy management hardware modules

Procurement Notes

Verify that the specific part number matches the required 44-position dual-edge specification before ordering. Confirm that the receiving PCB supports the 0.156-inch pitch and compatible thickness range. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly. Cross-reference the mounting hole pattern with the official mechanical drawing to validate panel fitment.

Selection Notes

Select this component when a high-density dual-edge interface with robust mechanical retention is required. The 0.156-inch spacing suits applications where standard 0.100-inch pitches are insufficient for current handling or signal isolation. Consider the through-hole termination method for superior durability compared to surface-mount alternatives in high-vibration environments.

Part Context

This connector belongs to the EDAC 306 Series, which specializes in standard card edge connectors with 0.156-inch spacing. The series offers various position counts and mounting styles to support diverse industrial and commercial electronic architectures. The 306-022 variant specifically addresses higher pin count requirements within this standardized footprint family.

Replacement Considerations

Direct substitutes within the same series include parts like 306-020-521-168 or 306-042-521-168, which share identical spacing and mounting characteristics but differ in contact count. Verify that any replacement maintains the dual-edge female configuration and compatible PCB thickness specifications.
