Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm mechanical variations such as flange type or plating thickness. Ensure compatibility with target PCB stack-up dimensions before procurement. Confirm RoHS compliance status via the manufacturer's latest datasheet revision. Cross-reference the Mouser part number 587-345-074-520-508 for accurate distributor identification. Validate that the selected variant matches the required current and thermal specifications for the intended application environment.

Edgeboard Connectors Selection Notes

Select this connector when a high-density 74-position interface is required for vertical board-to-panel connections. The 2.54 mm pitch allows for standard trace spacing on printed circuit boards. Consider the 3 A current rating for power distribution needs within the system architecture. The vertical orientation simplifies assembly in constrained enclosures where space efficiency is critical. Ensure the mating card edge thickness falls within the specified 1.37 mm to 1.78 mm range for optimal contact engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 345 series of standard card edge connectors. The series offers various position counts and termination options to support diverse electronic module requirements. The 345-074-520-508 specifically addresses applications needing dual-edge connectivity with through-hole reliability. Its design emphasizes durability in industrial and medical environments where consistent electrical performance is mandatory.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain identical 74-position count, 2.54 mm pitch, and dual-edge configuration. Verify that alternative components support the same 3 A current rating and -40°C to 105°C operating temperature range. Ensure mechanical compatibility regarding vertical mounting and flange placement. Check for equivalent gold plating specifications to guarantee comparable contact resistance and longevity.
