305-042-520-578

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-578 is a standard card edge connector from the 305 series, designed for panel mount installation with vertical orientation. It features 42 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are female type, constructed from copper alloy and gold-plated to ensure reliable signal transmission. Rated for 5 A current, it supports PCB thicknesses of 1.57 mm. The housing is made of green thermoplastic material, providing insulation resistance of 5 GOhms and operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for non-specified dual-edge card connections
• Gold-plated copper alloy contacts ensuring durable electrical performance
• Panel mount design with vertical orientation for secure structural integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific packaging and lead time requirements. Confirm RoHS compliance status and environmental certifications prior to ordering. Ensure compatibility with existing panel mounting hardware and PCB specifications. Check distributor availability as stock levels may vary by region. Validate that the 42-position count matches the target application design constraints.

Edgeboard Connectors Selection Notes

Select this component when a 42-position dual-row interface is required with a 3.96 mm pitch. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Verify that the panel mount style aligns with the mechanical enclosure design. Ensure the gold plating meets corrosion resistance needs for the intended operational lifespan.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and pitch options. Similar models include the 305-038-520-502 and 305-050-520-578, differing primarily in position count. The series is characterized by its thermoplastic housing and solder pin termination, widely used in industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-038-520-578 and 305-050-520-578, though position counts differ. Cross-series replacements require verification of pitch, row count, and mounting style. Ensure any alternative maintains the 3.96 mm spacing and dual-edge compatibility.
