305-072-520-207

Edgeboard Connectors Overview

The EDAC Inc. 305-072-520-207 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features 72 positions arranged in two rows with a pitch of 3.96 mm (0.156 inches). The connector supports a maximum PCB thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. Rated for 5 A current, it employs a solder pin termination type for secure board attachment. The housing is constructed from thermoplastic polyester, providing stability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 72 positions for high-density interconnect applications
• Gold-plated copper alloy contacts ensure corrosion resistance and stable electrical performance
• Thermoplastic polyester insulator provides thermal stability and mechanical strength
• Solder pin termination facilitates secure mounting on printed circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted connections
• Telecommunications equipment utilizing dual-edge card interfaces
• Automotive electronics demanding high-temperature reliability
• Test and measurement instrumentation needing precise signal routing

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific plating thickness, housing color, and mounting style variations. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the solder pin termination aligns with the assembly process capabilities. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.

Edgeboard Connectors Selection Notes

Select this component when a 72-position, two-row interface is required with a 3.96 mm pitch. Consider the vertical orientation and panel or PCB mount options based on system enclosure design. The 5 A rating and wide temperature range make it suitable for demanding environments where long-term connection integrity is critical compared to lower-rated alternatives.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and termination styles. It serves as a standard solution for card edge applications, distinct from the 307 series headers. The model specifies a female receptacle configuration with gold contacts, differentiating it from variants with tin plating or different row configurations within the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the 305 series designation, 72 positions, and identical 3.96 mm pitch. Verify mechanical dimensions and contact plating specifications before substitution. Cross-reference with other manufacturers only if exact dimensional and electrical parameters match the original requirements.
