Obsolete — sourcing reality for the BOM line
The DSC6021CI2A-009W: For a BOM that already carries this part, the remaining supply moves through independent distribution and surplus channels. If you are qualifying a replacement, the DSC60XX family uses a MEMS resonator and a standard 4-VDFN footprint; a pin-compatible drop-in from the same series would share the same package and supply range, but no direct cross-reference is published.
Board-fit and reflow considerations
It ships in a tube, not tape-and-reel, so plan for hand-load or tube feeders on the pick-and-place; the tube quantity may affect the per-panel placement cost for high-volume runs.
