How to use this cross-reference

  • Confirm PCB ball map, voltage rail, and speed grade against your Loongtion datasheet.
  • Run qualification on your target board — cross-reference describes documented alignment, not a blanket warranty of interchangeability.
  • For EOL or long-lead incumbent parts, contact for samples and BOM review (typically within 24 hours).
