305-072-520-501

Edgeboard Connectors Overview

The EDAC Inc. 305-072-520-501 is a standard card edge receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accommodates a board thickness of 1.57 mm (0.062 inch). The connector employs gold-plated copper alloy contacts with a solder termination type for PCB mounting. Rated for 5 A current, it offers an insulation resistance of 5 GOhms and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Dual-edge contact design for secure connection to double-sided circuit boards
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural stability and electrical insulation
• Straight through-hole mounting style facilitates direct PCB integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment interface modules
• Medical device internal board connections
• Automotive electronics subsystems

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact plating thickness, housing color, and termination style variations. Ensure compatibility with the target printed circuit board thickness of 1.57 mm prior to procurement. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with official EDAC documentation to avoid substitution errors due to similar series numbering.

Edgeboard Connectors Selection Notes

Select this component when a dual-side card edge connector with 72 positions is required. The 3.96 mm pitch suits applications needing high-density I/O without micro-pitch constraints. Verify that the 5 A current rating meets the electrical load requirements of the connected traces. Ensure the straight mounting orientation aligns with the mechanical layout of the enclosure and adjacent components on the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors designed for general-purpose electronic applications. The series offers various position counts and mounting styles to accommodate different board densities. The 305-072-520-501 specifically addresses needs for medium-to-high density connections in industrial and commercial environments where reliability and standard form factors are prioritized.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical pin counts and pitch, such as 305-072-521-201 or 305-072-520-204, provided the specific suffix variations match the application requirements. Verify mechanical dimensions and electrical ratings before substituting.
