305-070-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-070-521-504 is a standard card edge connector header featuring 70 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts with solder pin termination for secure electrical connections. Designed for panel mounting at a vertical orientation, it operates within a temperature range of -40°C to +105°C and supports a current rating of 5 A.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the enclosure design requirements. Cross-reference the 70-position count to prevent mismatched assembly errors during production integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required for vertical panel mounting. The 5 A current rating and -40°C to +105°C operating range suit environments with moderate thermal loads. Verify that the target application utilizes a 0.062 inch thick card edge PCB to ensure proper contact engagement and mechanical stability within the connector housing.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, designed for high-reliability interconnect solutions. The series offers various position counts and row configurations to support diverse electronic system architectures. As a header type, it mates with corresponding receptacles or directly with card edge PCBs, providing a standardized connection method for modular electronic designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the same 305 series designation, 70-position count, and 3.96 mm pitch, such as 305-070-521-507 or 305-070-556-568. Verify that alternative parts maintain identical panel mount orientation and vertical alignment. Confirm that replacement components match the original gold plating and thermoplastic insulation specifications for equivalent performance.
