305-018-556-207

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-207 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features an 18-position dual-edge female configuration with a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. This header supports PCB thicknesses of 1.57 mm and utilizes solder lug termination for secure board attachment. It operates within a temperature range of -40°C to +105°C and has a current rating of 5 A.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact termination style and flange options. Confirm availability status as distribution channels may indicate limited stock or regional restrictions. Ensure the selected variant matches the required PCB thickness tolerance of 1.57 mm for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a vertical, dual-edge connector with a 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Verify that the 18-position count aligns with the circuit board signal requirements before finalizing the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts up to 86 contacts in dual-row configurations. These connectors are engineered for high-reliability applications requiring stable electrical connections between edge cards and host boards in industrial and commercial environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for alternative position counts or termination styles. No direct cross-brand substitutes are confirmed in public documentation; verify mechanical dimensions and pin compatibility if considering other manufacturers.
