305-070-500-258

Edgeboard Connectors Overview

The EDAC 305-070-500-258 is a standard card edge connector from the 305 series, manufactured by EDAC Inc. It features a dual-row configuration with 70 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing measures 3.56 mm. Designed for panel mounting in a vertical orientation, it utilizes solder pin termination. The contacts are made of copper alloy with gold plating, rated for 5 A current. The insulator body is green thermoplastic, accepting printed circuit boards with a nominal thickness of 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Vertical panel mount style with solder lug termination
• Thermoplastic insulator housing provides electrical insulation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact count, row configuration, and termination type match project requirements. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure panel cutout dimensions align with the connector's flange specifications for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for thick PCB applications. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Verify that the 5 A current rating meets the thermal and electrical demands of the target application circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting options. The series is characterized by robust construction suitable for harsh environments. Similar parts in the series include 305-048-520-258 and 305-050-520-578, differing primarily in position count and specific termination details.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-070-520-258, which shares identical physical dimensions and electrical characteristics. Cross-brand replacements require careful verification of pitch, row spacing, and mounting hole patterns to ensure mechanical compatibility.
