305-064-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-064-556-203 is a standard card edge connector featuring 64 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. The component employs gold-plated copper alloy contacts with a solder lug termination type for secure electrical connections. Designed for panel mounting, it operates within a temperature range of -40°C to +105°C and carries a current rating of 5 A.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact termination style and flange characteristics. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required panel mounting orientation and current rating requirements for the intended application environment.

Edgeboard Connectors Selection Notes

Select this model when a high-pin-count dual-row interface is required for panel-mounted installations. The 3.96 mm pitch accommodates standard thick card edges. Consider the 5 A current rating and operating temperature limits for thermal management. Verify that the solder lug termination aligns with the assembly process and mechanical constraints of the host enclosure design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-064-556-203 specifically addresses needs for higher density connections in vertical panel configurations. It shares common material properties and electrical standards with other parts in the 305 family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 64-position dual-row layouts. Cross-reference pin counts, pitch dimensions, and termination types to ensure mechanical fit. Verify that alternative part numbers maintain identical current ratings and temperature ranges for equivalent performance.
