305-042-520-207

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-207 is a standard card edge connector header designed for panel mounting applications. It features a dual female configuration with 42 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, ensuring reliable signal transmission. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for secure card edge insertion
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Thermoplastic insulator housing providing structural stability and electrical isolation
• Vertical panel mount design with solder pin termination for robust PCB integration

Edgeboard Connectors Applications

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact pin count and termination style. Ensure compatibility with target PCB trace spacing and panel cutout dimensions. Confirm RoHS compliance status through manufacturer datasheets prior to procurement. Cross-reference lead times with authorized distributors as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a high-density vertical connection is required for double-sided edge cards. The 3.96 mm pitch suits applications needing fewer connections than fine-pitch alternatives but higher density than standard headers. Verify that the mating card thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper contact engagement and mechanical retention.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options tailored for diverse industrial and commercial interconnect needs. The 305 series is characterized by its durable thermoplastic construction and standardized panel mounting footprint, facilitating easy integration into existing chassis designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-042-520-202 or 305-042-500-504, provided they match the 42-position count and 3.96 mm pitch. Verify that alternative suffixes do not alter the termination type or flange characteristics. Always consult the latest ordering guide to confirm dimensional equivalence before substitution.
