305-068-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-068-556-503 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 68 positions with a 3.96 mm (0.156 inch) pitch and a 3.56 mm (0.140 inch) row spacing. The connector supports PCB thicknesses between 1.37 mm and 1.78 mm. It utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) finish and half-beam contact types. Rated for 5 A current, it operates within a temperature range of -40°C to 105°C and uses thermoplastic polyester insulation.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for non-specified card edge boards
• Gold-plated half-beam contacts ensure reliable electrical connection
• Panel mount style with top opening flange feature
• RoHS3 compliant construction using thermoplastic polyester insulation

Edgeboard Connectors Applications

• Industrial control panel interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Computer peripheral interface cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating thickness and material specifications. Ensure the target PCB thickness falls within the 1.37 mm to 1.78 mm operational range. Confirm RoHS3 compliance requirements match project standards. Cross-reference the 68-position count and 3.96 mm pitch with schematic footprints to prevent mechanical mismatch during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge interface with high pin density is required. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. The vertical panel mount style suits chassis-based installations. Consider the 5 A rating for power distribution needs. Verify that the green color coding aligns with internal board identification protocols if visual differentiation is necessary for maintenance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting styles for card edge applications. The series is characterized by robust mechanical design and standardized dimensions. Similar parts in the series include variants with different position counts such as 305-050 or 305-070, allowing for scalable design solutions within the same connector family while maintaining consistent pitch and mounting characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include 305-068-556-258, which shares identical mechanical and electrical specifications but may differ in packaging or specific environmental certifications. Always verify cross-references against the latest manufacturer documentation to ensure compatibility with existing tooling and assembly processes.
