Frequently Asked Questions

Which board-to-board interconnects designs fit FSA266K8X when 8 pins is required?

FSA266K8X fits designs needing a Connector with 8 pins and SMA packaging. Engineers commonly use it in board-to-board interconnects, module stacking, and high-reliability cable or socket assemblies, while checking derating, layout limits, and the manufacturer datasheet.

How should assembly teams evaluate FSA266K8X before approving the footprint?

Review the SMA package details and confirm 8 pins against the PCB land pattern. This helps buyers verify assembly method, inspection access, and substitute compatibility before purchase.

When is FSA266K8X a practical sourcing choice for replacement or production builds?

Use FSA266K8X when the BOM requirement matches 846A and the obsolete lifecycle status is acceptable. For urgent builds, request lot traceability, date codes, and confirmed shipment quantities.
