305-070-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-070-521-501 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 70 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts that are gold-plated, it ensures reliable electrical performance. The housing is made of green thermoplastic polyester, providing durability and insulation.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodates double-sided card edge PCBs.
• Gold-plated copper alloy contacts provide corrosion resistance and stable conductivity.
• Low-profile insulator body constructed from thermoplastic polyester for structural integrity.

Edgeboard Connectors Applications

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm physical dimensions and plating specifications against official datasheets. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for 70-position interfaces. The 3.96 mm pitch suits applications where standard spacing is mandated. Verify that the operating temperature range of -40°C to +105°C aligns with the environmental conditions of the end-use application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and mounting styles. The 305-070 variant specifically addresses high-density requirements within the standard pitch family, balancing connectivity needs with mechanical stability.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series parts for position count variations. Verify identical pitch and board thickness compatibility before substituting with similar dual-edge connectors from alternative manufacturers.
