305-026-556-504

Edgeboard Connectors Overview

The EDAC Inc. 305-026-556-504 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 26 positions with a 3.96 mm (0.156 inch) pitch and supports two contact rows. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. Designed for panel mounting in a vertical orientation, it accepts PCB thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure that the ordering part number matches the required position count and pitch dimensions. Confirm compliance with RoHS3 standards if environmental regulations apply to the target assembly. Cross-reference the datasheet for any recent updates regarding mechanical tolerances or mating force requirements before final procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 26-position connection is required with a 3.96 mm pitch. Verify that the host PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper retention. Consider the vertical panel mount style for space-constrained enclosures requiring direct board insertion. Ensure the operating environment stays within the -40°C to +105°C limit to maintain insulation resistance and contact performance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent pitch and mounting characteristics. The 305-026 variant specifically addresses applications needing 26 contacts. It shares common design principles with other parts in the family, such as the 305-016 and 305-022 models, differing primarily in contact quantity and overall physical length.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 26 positions and 3.96 mm pitch, such as 305-026-556-568. Verify that alternative suffixes do not alter critical electrical ratings or mechanical mounting styles. Ensure compatibility with existing tooling and PCB layouts before switching to different manufacturer equivalents.
