305-030-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-030-521-203 is a standard card edge connector from the 305 series, designed for panel mount and through-hole installation. It features 30 positions arranged in a dual-row configuration with a contact pitch of 3.96 mm (0.156 inches). The connector utilizes copper alloy contacts with gold plating and employs a solder pin termination method. It accepts printed circuit boards with a nominal thickness of 1.57 mm. The insulator body is constructed from thermoplastic material, providing an operating temperature range between -40°C and +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact mechanical dimensions and contact finish specifications. Ensure compatibility with target PCB thickness and mounting requirements before procurement. Cross-reference manufacturer part numbers with distributor listings to confirm current availability status and lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted applications. Consider the 1.57 mm board thickness tolerance and the -40°C to +105°C operational range. Evaluate the gold-plated copper alloy contacts for corrosion resistance and conductivity needs within the specific system environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations while maintaining consistent 3.96 mm spacing. These connectors are engineered for durability in demanding sectors, including medical and agricultural technologies, where stable electrical connections under varying conditions are critical.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for verified substitute part numbers. Direct replacements must match the 30-position count, dual-row layout, and 3.96 mm pitch. Verify that alternative parts support identical panel mounting styles and PCB thickness tolerances.
