Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact plating thickness and housing color specifications. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure design requirements.

Edgeboard Connectors Selection Notes

Select this model when a dual-row header with a 3.96 mm pitch is required for vertical panel mounting. It is suitable for applications demanding a 5 A current rating and operation up to 105°C. Verify that the 56-position count matches the circuit interface needs and that the through-hole solder pin termination method fits 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 styles, providing standardized interfaces for edgeboard applications. The 305-056-521-558 variant specifically addresses the need for a 56-contact vertical header with robust thermal and electrical performance characteristics.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 305-050-556-201 or 305-054-556-278 from the same manufacturer family if different position counts are acceptable. Ensure any substitute maintains the 3.96 mm pitch and vertical panel mount orientation.
