305-022-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-022-521-202 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 22 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester housing. Rated for 5 A current, it supports PCB thicknesses between 1.37 mm and 1.78 mm. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure mating with double-sided circuit boards
• Gold-plated half-bead contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural integrity and electrical insulation
• Panel mount configuration with flanged mounting holes for stable mechanical installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge modules
• Automotive electronics assemblies needing high-reliability connections
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness, housing color, and termination style. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the panel cutout dimensions align with the specified flange diameter of 3.25 mm for proper fitment during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with a 3.96 mm pitch is required for vertical panel mounting. The 22-position count suits moderate-density interface needs. Verify that the 5 A current rating meets the application's power requirements. Consider the operating temperature range of -40°C to +105°C for environmental suitability in industrial or automotive settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing common electrical characteristics like 5 A ratings and 3.96 mm pitch. The 305-022-521-202 specifically denotes a 22-position dual-edge variant with gold contacts and thermoplastic housing, distinct from single-edge or different pitch alternatives within the same family.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers such as 305-022-556-568 or 305-022-520-502 if similar specifications are needed. Verify that substitute parts maintain the same 22-position count, 3.96 mm pitch, and dual-edge configuration to ensure mechanical and electrical compatibility without redesigning the host system.
