305-046-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-046-556-503 is a standard card edge connector from the 305 series, designed for dual-row female connections. It features 46 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are made of copper alloy with gold plating, housed in a green thermoplastic insulator body.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 46 connection positions for high-density interface requirements
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic insulator body offers mechanical stability and environmental protection
• Vertical panel mount style facilitates secure installation in chassis applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard board thicknesses
• Test and measurement instruments needing reliable vertical mounting connectors

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and material variants. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the manufacturer part number with authorized distributors to confirm availability and lead times. Request updated datasheets to validate compliance with current RoHS directives and operating temperature ranges.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 46 positions is required. Verify that the application environment supports the specified operating temperature range of -40 C to +105 C. Confirm that the PCB design accommodates the 3.96 mm pitch and 1.57 mm thickness constraints. Evaluate the need for gold plating versus other finishes based on contact cycle requirements and environmental exposure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles while maintaining consistent electrical characteristics. The 305 series is widely used in industrial and commercial electronics where reliable vertical interconnection is necessary. Similar parts in the series differ primarily in position count and specific housing dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-040-556-503 and 305-054-556-503, which share identical pitch and mounting characteristics but differ in position count. Verify mechanical fit and electrical ratings before substitution. No alternative manufacturers are confirmed as direct replacements without custom engineering.
