Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB dimensions and mating card edge profiles before procurement. Cross-reference RoHS compliance status directly with manufacturer declarations.

Edgeboard Connectors Selection Notes

Select this model when a 72-position dual-row interface is required with a 3.96 mm pitch. Confirm that the application environment falls within the specified -40°C to +105°C operating range. Validate that the board thickness matches the connector's acceptance criteria for proper mechanical engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations designed for general-purpose electronic interconnections. The 305 series is characterized by its consistent 3.96 mm pitch across multiple variants.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC part numbers sharing the same 305 series designation, 72-position count, and dual-row configuration. Verify identical pitch, mounting style, and electrical ratings before substitution.
