305-020-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-020-556-258 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 20 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 5 A current rating per contact. Constructed with thermoplastic polyester insulation, 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 female configuration for non-specified dual-edge boards
• Gold-plated copper alloy contacts for enhanced conductivity
• Thermoplastic polyester housing for thermal stability
• Vertical panel mounting style with solder pin termination

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange dimensions. Ensure compatibility with the target PCB thickness limits before procurement. Cross-reference the RoHS status with current regulatory requirements for the intended market. Confirm that the vertical mounting orientation aligns with the mechanical assembly constraints of the final enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface is required with a 3.96 mm pitch. It is suitable for designs needing robust thermal performance up to 105°C. Consider the panel mount style if space-constrained vertical integration is necessary. Validate that the 5 A current capacity meets the power distribution requirements of the connected circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standardized card edge connectors for various industrial and commercial applications. The series offers multiple position counts and mounting variations. The 305-020 variant specifically addresses mid-density connection needs with a 20-position layout, balancing connectivity density with mechanical stability in compact form factors.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC ordering guide for direct cross-references. Verify that substitute parts maintain identical 3.96 mm pitch and dual-edge compatibility. Ensure mechanical footprint and mounting hole patterns match to avoid retooling.
