306-023-421-101

Overview

The EDAC Inc. 306-023-421-101 is a dual female card edge connector from the 306 series, designed for panel and through-hole mounting. It features 46 positions with a 0.156-inch (3.96mm) spacing across two rows of 23 contacts each. The connector utilizes copper alloy cantilever contacts with tin plating and a green thermoplastic polyester insulator. It supports PCB thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female configuration with cantilever contact type for reliable board insertion
• Panel mount design with flush flange and top opening for secure installation
• Tin-plated copper alloy contacts ensure corrosion resistance and conductivity
• Green thermoplastic polyester insulation provides stability in standard operating environments

Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard double-sided PCBs
• Test and measurement devices needing reliable high-density connections

Procurement Notes

Verify that the target PCB thickness falls within the specified 0.054 to 0.070 inch range to ensure proper mechanical engagement. Confirm that the application environment remains within the -40°C to 105°C operational limits. Ensure compatibility with the 0.156-inch pitch and 46-position layout during the initial design phase to avoid integration issues.

Selection Notes

Select this component when a dual-side female connector with tin plating is required for non-specified double-sided cards. It is suitable for applications where panel mounting with a flush flange is preferred over surface mount alternatives. Consider the 306 series specifications if higher temperature ratings or gold plating are not necessary for the specific use case.

Part Context

This part belongs to the EDAC 306 series, which focuses on standard card edge connectors with 0.156-inch spacing. The series offers various position counts and termination options, catering to general-purpose electronic interconnect needs. The 306-023-421-101 specifically addresses requirements for 46-position dual-row configurations with through-hole solder tail termination.

Replacement Considerations

Consult the official 306 Series Ordering Guide for alternative part numbers within the same family. Verify that any substitute maintains the 0.156-inch pitch, 46-position count, and dual female configuration to ensure mechanical and electrical compatibility.
