305-040-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-040-521-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual-row configuration with 40 positions and a pitch of 3.96 mm (0.156 inches). The connector supports a board thickness range of 1.37 mm to 1.78 mm (0.054" to 0.070"). Contacts are made of copper alloy with gold plating, rated for 5 A current. The housing is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, termination style, and flange specifications. Ensure compatibility with target PCB thickness limits before integration. Cross-reference manufacturer datasheets for updated environmental compliance status and mechanical drawing dimensions to prevent assembly errors during procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 40-position card edge interface is required with a 3.96 mm pitch. Confirm that the application environment stays within the specified -40°C to +105°C operational range. Verify that the mating card thickness falls within the 1.37 mm to 1.78 mm acceptance window. Ensure panel mounting constraints align with the vertical header profile.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is characterized by robust thermoplastic housings and gold-plated contacts suitable for high-reliability industrial environments. Similar parts in the series vary by position count and termination style, providing modular connectivity solutions for diverse electronic assemblies.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-040-520-507 and 305-040-520-268, which share identical 40-position counts, 3.96 mm pitch, and dual-row architecture. Verify that alternative suffixes match the required termination type and flange characteristics for direct interchangeability.
