305-018-555-203

Edgeboard Connectors Overview

The EDAC 305-018-555-203 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 accommodates printed circuit boards with a thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts to ensure reliable signal transmission, supporting a continuous current rating of 5 A. Designed for panel mounting in a vertical orientation, it offers an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm plating specifications and termination style. Confirm that the required polarizing key compatibility matches the application design. Ensure the PCB thickness falls within the specified tolerance range for proper mechanical retention. Check RoHS compliance status against project requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this model when a 3.96 mm pitch is required for high-reliability connections. Consider the vertical panel mount style for chassis integration needs. Evaluate the 5 A current rating against the total load requirements of the target circuit. Verify that the dual-edge card type matches the existing hardware design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting options while maintaining consistent electrical performance standards. The 305 series is widely recognized for its robust construction and suitability for demanding environments requiring stable connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 305-018-555-507 and 305-018-555-508. These alternatives share identical mechanical dimensions and electrical ratings but may differ in tail plating or packaging. Always verify cross-reference data sheets for exact pinout and dimensional compatibility.
