305-020-556-201

Edgeboard Connectors Overview

The EDAC Inc. 305-020-556-201 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features 20 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge card configurations. The connector utilizes gold-plated copper alloy contacts to ensure low contact resistance and corrosion resistance. Rated for 5 A current, it accommodates board thicknesses of 1.57 mm and operates within a temperature range of -40°C to +105°C. The unit employs solder pin termination for secure PCB mounting.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 20-position configuration and 3.96 mm pitch before procurement. Confirm that the gold plating specification meets the application's conductivity requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Cross-reference the datasheet for accurate dimensional tolerances to guarantee proper fit within the designated chassis or PCB layout constraints.

Edgeboard Connectors Selection Notes

Select this component when a robust, dual-edge card edge connector is required for moderate current applications. The 3.96 mm pitch offers a balance between density and spacing reliability. Consider the gold contact finish for environments requiring long-term stability against oxidation. Evaluate the thermoplastic polyester housing material for compatibility with soldering processes and thermal management needs during assembly.

Edgeboard Connectors Part Context

This connector belongs to EDAC's 305 series, which specializes in standard card edge solutions. The series provides various position counts and mounting styles to support diverse electronic design requirements. The 305-020-556-201 specifically addresses the need for a 20-position interface with durable contacts. It complements other components in systems requiring secure, plug-and-play connectivity for circuit boards.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variations such as 305-020-556-202 or 305-020-500-203, depending on specific mounting style or packaging requirements. Verify that any replacement maintains the 3.96 mm pitch and 20-position count. Ensure electrical ratings and material specifications remain identical to avoid re-validation of the mechanical and thermal performance.
