305-054-556-568

Edgeboard Connectors Overview

The EDAC Inc. 305-054-556-568 is a standard card edge connector header featuring 54 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and supports a PCB thickness of 1.57 mm. The component employs gold-plated copper alloy contacts with a solder pin termination type for secure electrical connection. Designed for panel mounting at a vertical angle, it offers a current rating of 5 A. The insulator is constructed from thermoplastic material, providing an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

• Vertical panel mount style with solder pin termination
• Thermoplastic insulator housing provides structural stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Computer peripheral interface boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact plating thickness and flange specifications. Ensure compatibility with the target PCB stack-up regarding the 1.57 mm board thickness requirement. Confirm that the vertical panel mounting orientation aligns with the mechanical enclosure design constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row connection is required for thick PCB applications. The 3.96 mm pitch accommodates larger trace spacing compared to finer pitches. Verify that the 5 A current rating meets the circuit load requirements. Consider the vertical mounting profile for space-constrained panel installations where front-access is necessary.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a range of card edge connectors with varying position counts. The series shares common mechanical dimensions and electrical characteristics, differing primarily in the number of contacts. This specific model represents a mid-range position count within the dual-row product family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical pitch and row configuration but different position counts, such as 305-050-556-568 or 305-056-556-568. Cross-manufacturer replacements require matching the 3.96 mm pitch, dual-row layout, and panel mount style.
