305-038-556-568

Edgeboard Connectors Overview

The EDAC Inc. 305-038-556-568 is a standard card edge connector header from the 305 series, designed for panel mount installation at a vertical angle. It features 38 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy with gold plating and utilize a solder pin termination type. The housing is constructed from green thermoplastic polyester, supporting PCB thicknesses between 1.37 mm and 1.78 mm. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified dual-sided circuit boards.
• Panel mount style with vertical orientation ensures secure structural integration.
• Gold-plated copper alloy contacts provide reliable electrical conductivity.
• Thermoplastic polyester insulation offers stability across specified operating temperatures.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify that the target printed circuit board thickness falls within the 1.37 mm to 1.78 mm acceptance range to ensure proper mechanical engagement. Confirm that the mating card edge utilizes a dual-sided conductive trace layout compatible with the dual-row female contact structure. Ensure the application environment remains within the -40°C to +105°C operational limits to maintain insulation resistance and contact integrity throughout the product lifecycle.

Edgeboard Connectors Selection Notes

Select this component when a 38-position vertical interface is required for panel-mounted assemblies. The 3.96 mm pitch dictates specific board spacing requirements compared to finer pitch alternatives. Verify compatibility with existing thermal management strategies, as the 5 A rating per contact influences heat dissipation needs. Consider the green housing color for visual identification if distinguishing multiple connector types within a dense assembly is necessary for maintenance or inspection purposes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which provides standardized card edge connectors for various position counts. The series maintains consistent dimensional profiles and electrical characteristics across different configurations, allowing for modular design approaches. The 305-038 variant specifically addresses applications requiring a moderate number of connections in a compact vertical footprint, balancing density with ease of manual or automated insertion.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but differing position numbers, such as 305-022-556-568 or 305-054-556-278, provided the board layout supports the change. Cross-series replacements require verification of pitch, mounting style, and contact geometry to ensure mechanical fit and electrical performance match the original design specifications.
