305-060-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-060-556-203 is a standard card edge connector from the 305 series, designed for dual-row board edge applications. It features 60 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and includes a green thermoplastic polyester insulator. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 60 contact positions for high-density interconnects
• Gold-plated copper alloy contacts ensuring corrosion resistance and stable conductivity
• Green thermoplastic polyester housing offering thermal stability up to +105°C
• Straddle mount installation style compatible with 1.57 mm thick printed circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation needing reliable signal pathways
• Automotive electronics operating in extended temperature environments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact pin count, termination type, and mounting orientation. Ensure compatibility with the target PCB thickness of 1.57 mm and validate that the dual-row straddle mount style aligns with the mechanical design constraints of the assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Confirm that the application environment stays within the specified -40°C to +105°C operational range. Verify that the PCB layout accommodates the straddle mount footprint and that the 5 A current rating meets the electrical load requirements of the circuit design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a comprehensive range of standard card edge connectors. The series offers various position counts and mounting options, all sharing a consistent 3.96 mm pitch. This specific model represents a mid-range position count option within the series, balancing density and mechanical stability for general-purpose electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 60-position dual-row configurations and 3.96 mm pitch. Cross-brand replacements must strictly match the 3.96 mm pitch, 1.57 mm PCB thickness tolerance, and dual-row straddle mount geometry to ensure mechanical fit.
