305-018-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-503 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features an 18-position dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector supports printed circuit boards with a thickness range of 1.37 mm to 1.78 mm (0.054" to 0.070"). Contacts are constructed from copper alloy and gold plated, rated for 5 A current. It utilizes solder lug termination and thermoplastic insulation, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 18 positions for high-density signal routing
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic housing offers thermal stability up to +105°C
• Vertical panel mount design facilitates secure structural integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels
• Automotive electronics assemblies

Edgeboard Connectors Procurement Notes

Verify the specific termination style against project requirements, as the 305 series includes variants with both solder pin and solder lug options. Confirm that the target PCB thickness falls strictly within the 1.37 mm to 1.78 mm specification to ensure proper mechanical retention. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability status and lead times prior to finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount interface is required for 18 signals with a 3.96 mm pitch. Ensure the application environment remains within the specified -40°C to +105°C operational range. Verify compatibility with the intended PCB thickness limits. Consider the solder lug termination method if through-panel soldering is preferred over standard surface mount techniques.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standardized card edge solutions with a consistent 3.96 mm pitch across various position counts. The series is characterized by its versatility in mounting styles and termination types, catering to diverse industrial and commercial electronic enclosure requirements while maintaining uniform mechanical dimensions.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series connectors with matching 18-position dual-row layouts and 3.96 mm pitch. Ensure any replacement maintains the same vertical panel mount orientation and compatible PCB thickness range. Verify that the alternative part specifies identical solder lug termination to preserve assembly integrity.
