305-018-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-018-500-203 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features an 18-position dual-row configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The unit accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating and utilize a solder lug termination type. The insulator body is made of thermoplastic material.

• Low profile insulator body design for compact integration
• Gold-plated copper alloy contacts for corrosion resistance
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel connections
• Test and measurement equipment interfaces
• Communication hardware backplanes
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct termination and housing variations. Confirm that the target application supports the specified 1.57 mm board thickness tolerance. Check regional availability as distribution may be restricted in certain areas. Ensure compliance with RoHS3 standards if required by project specifications. Cross-reference the part number with the latest datasheet to confirm current production status and lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 18 positions is required for panel-mounted assemblies. The 3.96 mm pitch is suitable for general-purpose interconnects where space allows. Consider the solder lug termination for secure mechanical attachment during panel assembly. Evaluate the thermal operating range of -40°C to +105°C against environmental conditions. Compare against other series members if different board thicknesses or contact counts are needed.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various configurations for card edge applications. The series provides options for different position counts and termination styles while maintaining consistent electrical performance. The 305-018-500-203 specifically addresses needs for moderate density connections with high durability. It complements other components in system designs requiring standardized interface protocols.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-018-555-508, though verification of termination differences is essential. Ensure any replacement matches the 18-position count and 3.96 mm pitch exactly. Check for compatibility with existing panel cutouts and mounting hardware. Validate that alternative parts maintain the same current rating and temperature specifications.
