305-072-520-204

Edgeboard Connectors Overview

The EDAC 305-072-520-204 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 is designed for a board thickness of 1.57 mm. The connector employs gold-plated copper alloy contacts with a solder tail termination style for PCB mounting. Constructed with a thermoplastic polyester housing, it supports a current rating of 5 A and offers an insulation resistance of 5 GOhms. The unit operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row receptacle design accommodating 72 contact positions
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester housing provides structural integrity and insulation
• Solder tail termination facilitates secure printed circuit board mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment interface modules
• Automotive electronics assemblies
• Medical device hardware connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm housing color and contact plating specifications. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before integration. Confirm that the solder tail termination method aligns with the assembly process capabilities. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row connection is required for thick boards. The 3.96 mm pitch suits applications where space efficiency does not demand finer geometries. Consider the 5 A current rating for power distribution needs. Evaluate the operating temperature range against environmental conditions. Compare against single-row alternatives if position count allows for reduced profile.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series includes various position counts and row configurations. Similar models like 305-072-521-201 share identical electrical and mechanical specifications but may differ in housing color or minor manufacturing variations. The series is widely used in general electronic interconnect applications.

Edgeboard Connectors Replacement Considerations

The model 305-072-521-201 is documented as having identical technical specifications including position count, pitch, and ratings. Verify housing color differences if aesthetic matching is critical. No other direct substitutes are confirmed in the provided documentation.
