Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating, row count, and mounting style compatibility. Confirm that the target printed circuit board thickness aligns with the specified 1.57 mm nominal requirement to guarantee proper mechanical retention and electrical performance during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 72 positions is required for vertical or straight PCB mounting. Ensure the application environment stays within the -40°C to +105°C operational limits. Verify that the system voltage does not exceed the 1800 VACrms dielectric rating and that the board thickness accommodates the specified contact length for optimal engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial applications. The series is characterized by its durable thermoplastic construction and precise contact spacing. The 305-072-555-204 specifically represents a high-density variant optimized for dual-edge female connections in modular electronic assemblies.

Edgeboard Connectors Replacement Considerations
