305-042-500-258

Edgeboard Connectors Overview

The EDAC Inc. 305-042-500-258 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions arranged in two rows with a 3.96 mm pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. Rated for 5 A current, it supports PCB thicknesses between 1.37 mm and 1.78 mm. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for double-sided card edge boards
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Panel mount installation style with vertical orientation
• Thermoplastic polyester insulation provides structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Automotive electronics demanding high-temperature operational reliability
• Test and measurement instrumentation needing secure board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, flange dimensions, and mounting hardware specifications. Ensure compatibility with target PCB thickness ranges of 1.37 mm to 1.78 mm. Confirm RoHS compliance status through manufacturer datasheets prior to integration into regulated assemblies.

Edgeboard Connectors Selection Notes

Select this component when a 42-position dual-row interface is required for double-sided cards. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. Verify that the panel mounting style aligns with chassis design constraints. Consider the 5 A current rating for power distribution requirements within the system architecture.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series provides standardized solutions for card edge connectivity. Similar parts in the series differ by position count, such as the 305-038 or 305-082 variants, while maintaining consistent pitch and material characteristics across the family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 42 positions and 3.96 mm pitch, such as 305-042-520-202. Cross-brand replacements require verification of mechanical footprint, electrical ratings, and contact geometry to ensure functional equivalence without redesigning the host panel or PCB.
