305-056-555-207

Edgeboard Connectors Overview

The EDAC Inc. 305-056-555-207 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 56 positions in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder lug termination. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is made of thermoplastic material, and it accommodates a board thickness of 1.57 mm.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB edge thickness of 1.57 mm before integration. Cross-reference the 56-position count and dual-row layout with schematic requirements. Confirm that the solder lug termination method aligns with the assembly process capabilities. Check for any regional distribution restrictions or RoHS compliance details provided by authorized suppliers.

Edgeboard Connectors Selection Notes

Select this component when a high-density 56-position interface is required for vertical panel mounting. The 3.96 mm pitch offers a balance between signal density and spacing reliability. Choose this model if gold-plated contacts are necessary for corrosion resistance in demanding environments. Consider the thermoplastic housing durability for industrial settings. Ensure the 5 A current rating meets the power distribution needs of the connected modules.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and termination options to suit different design constraints. The 305-056-555-207 specifically addresses applications requiring robust dual-edge connectivity with standardized dimensions. It complements other components in the same family that share similar mechanical footprints but differ in pin counts or termination styles.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with identical 56-position dual-row layouts and 3.96 mm pitch. Verify mechanical compatibility with existing panel cutouts and PCB edge guides. Alternative manufacturers offering similar card edge connectors must match the critical dimensions and electrical ratings precisely.
