305-044-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-258 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features a dual female configuration with 44 positions and a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A. The connector accepts PCBs with thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified card edge applications
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical panel mount design with solder pin termination
• Accepts between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronics assemblies

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and pitch specifications before procurement. Confirm that the supplier provides official documentation, including the datasheet and mechanical drawings, to ensure compliance with design requirements. Check RoHS status and environmental certifications if applicable to your project standards. Ensure compatibility with existing polarizing key systems if used in conjunction with other connectors in the same assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, vertical card edge connector with a 3.96 mm pitch is required. Consider the 5 A current rating and operating temperature range for suitability in your application environment. Verify that the PCB thickness falls within the specified acceptance range. Evaluate the need for polarizing keys if system integrity requires it. Compare against other series members if different position counts or mounting styles are needed.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers a range of standard card edge connectors. The series provides various position counts and mounting options to accommodate diverse design needs. The 305 series is known for its reliability and compatibility with industry-standard card edge boards. Other parts in the series may differ in position count, but share similar electrical characteristics and material compositions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include models with identical pitch and row configuration but different position counts, such as 305-044-521-202 or 305-044-521-278, provided the position count matches the design requirement. Cross-series replacements require verification of pitch, current rating, and mechanical dimensions.
