Obsolete — sourcing reality for the BOM line
The DSC6021CI2A-00EMT: No pin-compatible direct replacement from Microchip is documented, so a board spin or a parametric search for a dual-output MEMS XO in the same 4-VDFN footprint is the migration path for new designs.
This is the standard DSC60XX land pattern — the same footprint serves the active DSC60XX variants if a non-obsolete drop-in is needed.
