305-048-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-048-556-203 is a standard card edge connector header featuring 48 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB board thicknesses of 1.57 mm. The contacts are constructed from copper alloy with gold plating, rated for 5 A current. This vertical panel-mount component operates within a temperature range of -40°C to +105°C and includes a green thermoplastic polyester insulator.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure card insertion
• Vertical panel mounting style with solder pin termination
• Gold-plated copper alloy contacts for reliable conductivity
• Thermoplastic polyester housing for thermal stability

Edgeboard Connectors Applications

• Industrial control system backplanes

• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB thickness tolerances before procurement. Confirm RoHS compliance status through manufacturer datasheets rather than distributor summaries.

Edgeboard Connectors Selection Notes

Select this model when a 48-position dual-row interface with a 3.96 mm pitch is required. Verify that the application environment stays within the -40°C to +105°C operating range. Ensure the mating card edge thickness falls within the specified mechanical tolerance for proper contact engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, providing standardized interfaces for high-reliability applications requiring robust electrical connections between circuit boards and backplanes.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 305-048-556-204 or 305-048-520-203 for alternative configurations within the same series. Verify identical pitch, row count, and mounting style before substitution to maintain mechanical fit.
