305-072-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-202 is a standard card edge connector receptacle from the 305 series, designed for PCB mount applications. It features 72 positions with a dual row configuration and a 3.96 mm (0.156 inch) pitch. The connector supports a maximum board thickness of 1.57 mm and operates within a temperature range of -40°C to +105°C. Contacts are made of copper alloy with gold plating, rated for 5 A current. The housing is constructed from thermoplastic polyester, providing an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 72-position dual row specification and 3.96 mm pitch. Confirm that the operating environment falls within the -40°C to +105°C temperature range. Ensure the target printed circuit board thickness does not exceed 1.57 mm to guarantee proper mechanical engagement. Check for RoHS compliance documentation if environmental regulations apply to the assembly process.

Edgeboard Connectors Selection Notes

Select this component when a straight-mount, dual-row card edge connector is required for high-reliability applications. The 5 A current rating and gold plating make it suitable for demanding signal integrity needs. Consider the 305 series compatibility if integrating with existing EDAC mating cards. Evaluate the thermoplastic polyester housing durability against chemical exposure in the specific deployment environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and configurations to support diverse board-to-board connection requirements. The 305-072-521-202 specifically addresses the need for a 72-position interface with standardized dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 72-position and 3.96 mm pitch specifications, such as 305-072-520-204, provided the end termination type matches the design constraints. Verify that any alternative maintains the same 5 A current rating and thermal performance characteristics.
