305-018-556-208

Edgeboard Connectors Overview

The EDAC 305-018-556-208 is a standard card edge connector featuring 18 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for vertical panel mount installation with solder lug termination. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A. The housing is made of green thermoplastic polyester rated UL 94V-0. It accommodates board thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact termination type and housing color variations. Ensure compatibility with the target PCB thickness specifications before procurement. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc. to meet environmental standards for the intended deployment region.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating and gold contact plating make it suitable for general-purpose industrial signals. Consider the vertical orientation and solder lug termination method during mechanical layout planning to ensure proper clearance and assembly alignment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles while maintaining consistent electrical characteristics. The 305-018-556-208 specifically represents an 18-position variant within this family, sharing common design features such as the thermoplastic housing material and gold contact finish found across similar models.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 18-position dual-row configurations. Verify that alternative parts maintain the same 3.96 mm pitch and 5 A current rating. Ensure the replacement supports vertical panel mounting and compatible solder lug termination methods.
