305-012-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-012-521-258 is a standard card edge connector from the 305 Series, designed for dual-row applications with 12 positions. It features a contact spacing of 3.96 mm (0.156 inches) and utilizes gold-plated copper alloy contacts for reliable signal transmission. The connector supports panel mounting with a vertical orientation and employs solder lug termination. It is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The unit operates within a temperature range of -40°C to +105°C and includes a thermoplastic insulator body.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Cross-reference the part number with authorized distributors to validate supply chain authenticity and avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted applications. The 12-position count suits moderate I/O density needs. Consider the vertical mounting style and solder lug termination for assembly constraints. Evaluate the operating temperature range of -40°C to +105°C against environmental conditions. Compare against other series members if different board thicknesses or row configurations are necessary.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its 3.96 mm contact spacing and low-profile insulator bodies. Similar models in the lineup include variants with different pin counts and mounting styles, allowing for scalable design solutions across multiple hardware platforms while maintaining consistent electrical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-014-521-258 and 305-016-521-501, though these differ in position count. Verify that any alternative maintains the 3.96 mm pitch and dual-row architecture. Check mechanical fitment for panel cutouts and PCB thickness tolerance before substitution.
