306-011-421-103

Edgeboard Connectors Overview

The EDAC Inc. 306-011-421-103 is a standard card edge connector receptacle designed for dual-edge PCB insertion. It features 22 positions with a 3.96 mm (0.156 inch) contact spacing and supports a nominal board thickness of 1.57 mm. The connector utilizes copper alloy contacts with tin plating and a green thermoplastic polyester insulator body. Rated for 5 A current, it offers vertical panel mount installation with solder pin termination. Operating temperatures range from -40°C to +105°C, ensuring reliable performance in industrial applications requiring secure dual-edge interface connections.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for non-specified dual-edge printed circuit boards
• Vertical panel mount configuration with solder pin termination for secure mechanical attachment
• Thermoplastic polyester insulator body providing electrical insulation and environmental resistance
• Copper alloy contacts with tin plating to ensure low contact resistance and corrosion protection

Edgeboard Connectors Applications

• Industrial control systems requiring robust dual-edge card interfaces
• Telecommunications equipment utilizing standardized card edge modules
• Test and measurement instrumentation with modular circuit board architectures
• Automotive electronics assemblies needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating, insulator color, and mounting style variations. Ensure compatibility with the target PCB's dual-edge thickness specifications before procurement. Confirm RoHS compliance status through the latest component documentation. Cross-reference the distributor's part number with the EDAC manufacturer part number to avoid substitution errors during sourcing.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 22 positions and 3.96 mm pitch is required. Verify that the application PCB thickness falls within the specified tolerance for reliable contact engagement. Consider the tin-plated contacts for general-purpose environments where gold plating is not strictly necessary. Ensure the vertical panel mount style aligns with the enclosure design requirements and available mounting space.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of standard card edge connectors, which are widely used in modular electronic systems. The series provides various position counts and mounting options to accommodate different PCB form factors. The 306-011-421-103 specifically addresses applications requiring dual-edge connectivity with a fixed 22-position layout, offering a balance between density and mechanical stability for standard industrial interconnect needs.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitute part numbers with identical electrical and mechanical parameters. Verify that any replacement maintains the same 3.96 mm pitch and 22-position count. Ensure the replacement connector supports the same PCB thickness and panel mount style. Cross-check contact material and plating specifications to maintain signal integrity and environmental durability.
