Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure that the procurement channel sources genuine components directly from authorized distributors or the manufacturer to avoid counterfeit parts. Cross-reference the RoHS compliance status with the latest regulatory updates before finalizing purchase orders.

Edgeboard Connectors Selection Notes

Select this model when a high-density connection with a 3.96 mm pitch is required for panel-mounted systems. The dual-row layout maximizes pin count within a compact footprint. Consider the 5 A current rating and wide operating temperature range for environments subject to thermal fluctuations. Confirm compatibility with the target PCB edge thickness of 1.57 mm during the mechanical design phase.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which are engineered for robust performance in demanding electronic applications. The series offers various position counts and mounting styles to accommodate diverse design requirements. As a standard header type, it facilitates reliable electrical connections between circuit boards and external interfaces in professional hardware setups.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 74-position counts and 3.96 mm pitch, such as 305-074-555-204, provided the housing color and specific termination details align with the design constraints.
