305-076-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-076-521-502 is a standard card edge connector from the 305 series, designed for dual female edgeboard applications. It features 76 positions with a 3.96 mm (0.156 inch) pitch and supports board thicknesses of 1.37 mm to 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin plating thickness and half-beam contact types. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, ensuring compliance with RoHS3 standards.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact plating thickness, flange style, and termination type. Ensure compatibility with the target PCB panel mounting requirements and verify that the selected variant meets the required RoHS3 compliance specifications for your region.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided female connector with a 3.96 mm pitch is required. Confirm that the mating card thickness falls within the specified 1.37 mm to 1.78 mm range. Validate that the vertical panel mount orientation aligns with the mechanical design constraints of the enclosure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers a range of standard card edge connectors. The series provides various position counts and termination options, allowing engineers to scale connectivity density while maintaining consistent mechanical interfaces and electrical performance characteristics across different system designs.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination styles. Cross-reference compatible parts from other manufacturers only if mechanical dimensions and electrical ratings are identical.
