305-016-556-504

Edgeboard Connectors Overview

The EDAC 305-016-556-504 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features a dual-row configuration with 16 positions and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts with a thickness of 10.0 µin (0.25 µm). It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, accommodating board thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure mating with non-specified card edges
• Vertical panel mount style with flush flange and top opening
• Gold-plated semi-beehave contacts for reliable signal transmission
• Thermoplastic polyester insulator providing high insulation resistance

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating thickness and material specifications. Confirm that the target application requires the 3.96 mm pitch and dual-row configuration. Check RoHS compliance status if environmental regulations apply to the end product. Ensure compatibility with the specified PCB thickness range of 1.37 mm to 1.78 mm before procurement.

Edgeboard Connectors Selection Notes

Select this component when a robust, vertically mounted card edge interface is required for industrial environments. The 3.96 mm pitch offers higher current capacity compared to finer pitches. The gold plating ensures durability in repeated insertion cycles. Consider the panel-mount requirement and the need for a dual-sided card connection. Verify thermal stability requirements against the -40°C to +105°C operating range.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its 3.96 mm pitch and versatile mounting options. Variations within the series differ primarily in position count, row configuration, and contact materials. The 305 series is widely used in applications requiring reliable, high-density connections on thick circuit boards.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching pitch and row count, such as 305-012-556-504 or 305-028-556-504, provided the position count aligns with the design. Cross-brand replacements must match the 3.96 mm pitch, dual-row layout, and vertical panel mount style to ensure mechanical fit.
