306-023-421-104

Overview

The EDAC Inc. 306-023-421-104 is a dual female card edge connector designed for panel mount and through-hole termination. It features 86 positions arranged in two rows of 43 contacts with a 0.156-inch (3.96mm) spacing. The connector utilizes copper alloy cantilever contacts with tin plating, housed in a green thermoplastic polyester insulator. It supports board thicknesses from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-sided female contact configuration for secure board retention
• Cantilever spring contact design ensures reliable electrical connection
• Thermoplastic polyester insulation provides thermal stability
• Panel mount installation with flush flange characteristics

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control units

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 306 Series Ordering Guide to ensure compatibility with required mounting styles and termination types. Confirm that the tin-plated contacts meet the environmental requirements for the intended application, as surface finish options may vary across different part number configurations within the same series.

Selection Notes

Select this component when a dual-row female connector with 0.156-inch spacing is required for high-reliability applications. Ensure the mating card edge thickness falls within the specified 0.054 to 0.070-inch range. Consider the operating temperature limits and the need for through-hole soldering when integrating into the final assembly design.

Part Context

This part belongs to the EDAC 306 Series, which offers various mounting options and contact terminations. The series is designed for robust performance in demanding environments, providing multiple card guide solutions and high-temperature insulator options to suit diverse industrial and commercial connectivity needs.

Replacement Considerations

Consult the official EDAC 306 Series cross-reference documentation for verified substitute part numbers. Direct replacements must match the 86-position count, 0.156-inch pitch, and dual female configuration to maintain mechanical and electrical interface integrity.
