305-044-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-044-556-278 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 44 positions with a 3.96 mm pitch and supports a maximum current rating of 5 A. The connector utilizes gold-plated copper alloy contacts housed in a green thermoplastic body. It is configured for vertical panel mounting with solder pin termination. The unit operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row configuration with gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic housing providing structural integrity and electrical insulation
• Vertical panel mount design with solder pin termination for secure installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge board connections
• Telecommunications equipment utilizing dual-edge card interfaces
• Test and measurement instrumentation with high-density I/O requirements

Edgeboard Connectors Procurement Notes

Verify part number accuracy against official EDAC documentation before procurement. Confirm that the specific suffix matches the required contact plating and housing color specifications. Ensure compatibility with the target PCB thickness and mounting style. Cross-reference RoHS compliance status with current regulatory requirements for the intended market. Validate supplier authorization to guarantee component authenticity.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row, 44-position interface with a 3.96 mm pitch is required. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Evaluate the vertical panel mount style against available chassis space. Compare alternative positions within the 305 series if different density or row configurations are needed. Assess thermal management needs relative to the thermoplastic housing material.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options while maintaining consistent 3.96 mm pitch dimensions. The 305-044-556-278 specifically addresses applications needing 44 positions with dual-edge connectivity. It shares common design principles with other parts in the family, such as gold-plated contacts and thermoplastic construction.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical pitch and row count but differing position numbers, such as 305-048-556-278 or 305-054-556-278. Verify mechanical fit and electrical ratings before substitution. No cross-manufacturer replacements are confirmed in public documentation.
