305-026-555-201

Edgeboard Connectors Overview

The EDAC Inc. 305-026-555-201 is a standard card edge connector from the 305 series, designed for board edge straddle mount installation. It features 26 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge non-specified cards with thicknesses between 1.37 mm and 1.78 mm. The contacts are made of copper alloy with gold plating, rated for 5 A current at up to +105 °C. Termination is achieved via solder pins, and the housing is constructed from green thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Straddle mount design for secure board edge connection
• Gold-plated copper alloy contacts for reliable conductivity
• Thermoplastic polyester insulation for durability

Edgeboard Connectors Applications

• PCB-to-PCB interconnection in modular systems
• Backplane connectivity for industrial control units
• Edgeboard extension applications

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required card thickness and termination style. Confirm RoHS compliance status and environmental ratings prior to integration. Cross-reference the part number with authorized distributors to validate supply chain authenticity and avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a vertical or straddle-mount card edge interface is required with a 3.96 mm pitch. Ensure the target PCB stack-up accommodates the specified contact length and that the mating card falls within the 1.37 mm to 1.78 mm thickness range. Consider the 5 A current rating and operating temperature limits for thermal management.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard density card edge connectors. The series offers various position counts and mounting styles, utilizing consistent 3.96 mm spacing. The 305-026 variant specifically provides a 26-position configuration suitable for moderate-density signal routing in electronic assemblies requiring robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical pitch and position count, such as 305-026-521-501, provided the termination and mounting style match. Verify cross-compatibility with generic card edge connectors only if pinout and mechanical dimensions are strictly aligned.
