Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact termination style, plating thickness, and mounting options. Ensure compatibility with the target board thickness of 0.062 inches. Confirm that the dual female configuration aligns with the system design requirements before procurement.

Edgeboard Connectors Selection Notes

Select this connector when a dual female interface is required for 0.156-inch spaced contacts. Consider the 0.200-inch row spacing for layout constraints. Verify thermal requirements as this is a high-temperature series component. Ensure the application supports the specified 0.062-inch board thickness for proper mechanical engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 857 series of high-temperature card edge connectors. The series offers various contact terminations, mounting options, and guide solutions. It is part of a broader family of edgeboard connectors designed for robust industrial and commercial electronic applications requiring reliable signal transmission.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 857 series variants such as 857-052-440-204 or 857-052-522-204 for alternative termination or mounting configurations. Verify that any substitute maintains the same 0.156-inch contact spacing and 0.062-inch board thickness compatibility.
