305-020-555-203

Edgeboard Connectors Overview

The EDAC 305-020-555-203 is a standard card edge connector receptacle featuring 20 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and supports printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts to ensure reliable signal transmission and corrosion resistance. Designed for panel mount installation, this connector offers a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing structural integrity and electrical insulation.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, row spacing, and mounting style variations. Ensure compatibility with target PCB thickness specifications before procurement. Cross-reference manufacturer part numbers with distributor catalogs to avoid substitution errors due to minor specification differences.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge connector with 20 positions and 3.96 mm pitch is required. Confirm that the application environment falls within the specified operating temperature range. Evaluate mechanical constraints to ensure the low-profile body fits within the designated enclosure space. Verify that the 5 A current rating meets the system's power distribution requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and accommodating standard PCB thicknesses. The 305 series is widely used in applications demanding high reliability and consistent performance across diverse industrial environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC part numbers within the same 305 series family, such as 305-020-500-203 or 305-020-521-203, provided they match the position count, pitch, and mounting style. Always verify dimensional drawings and electrical ratings before substituting.
