Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm mechanical dimensions and plating specifications. Ensure compatibility with the target PCB card thickness and panel cutout requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability status.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required. Consider the 5 A current rating and operating temperature range for environmental suitability. Verify that the vertical panel mount style aligns with the system's mechanical constraints and that the solder pin termination matches the assembly process.

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 options, characterized by a consistent 3.96 mm pitch. These connectors are engineered for durability and are commonly used in applications demanding reliable electrical connections between circuit boards and chassis-mounted headers.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for alternative part numbers with different position counts or mounting styles. Direct substitutes must maintain the 3.96 mm pitch and dual-row configuration to ensure mechanical and electrical compatibility.
