305-026-556-503

Edgeboard Connectors Overview

The EDAC Inc. model 305-026-556-503 is a standard card edge connector designed for dual-edge board insertion. It features 26 positions with a row spacing of 3.96 mm (0.156 inches) and accommodates a nominal PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. 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 Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to confirm pin count, plating type, and housing color. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the 3.96 mm row spacing aligns with the design layout. Confirm RoHS compliance status prior to final procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with 26 positions is required. The 3.96 mm pitch and 1.57 mm board thickness are critical constraints. Verify that the vertical mounting style and 5 A current rating meet the application requirements. Compare against other 305 series variants if different pin counts or orientations are needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series is characterized by its robust thermoplastic construction and gold-plated contacts. These connectors are engineered for high-reliability applications requiring stable electrical connections between circuit boards and chassis-mounted receptacles.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series cross-reference guide for direct substitutes. Verify that any alternative maintains the identical 26-position count, 3.96 mm pitch, and 1.57 mm board thickness compatibility.
