Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB edge thickness of 1.57 mm before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status. Confirm that the vertical orientation aligns with the mechanical constraints of the final enclosure design.

Edgeboard Connectors Selection Notes

Select this model when a 3.96 mm pitch is required for dual-row card edge connections. Consider the 5 A current rating and thermal limits when designing for high-power environments. Verify that the panel mount style fits the chassis requirements compared to board-mount alternatives. Ensure the solder pin termination method matches the available PCB fabrication capabilities for reliable joint formation during assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options tailored for diverse electronic packaging needs. The 305 series is widely recognized in industrial and commercial sectors for its reliability and standardized dimensions, supporting both single and dual-row configurations across multiple pitch options.

Edgeboard Connectors Replacement Considerations

Consult EDAC technical support for alternative part numbers within the 305 or 355 series that match the 74-position requirement. Verify dimensional tolerances and contact plating specifications before substituting with generic equivalents. Ensure any replacement maintains the 3.96 mm pitch and vertical mounting orientation.
