Obsolete — no official successor on record
Microchip Technology has classified the DSC6121HI2A-00AQT as Obsolete. Sourcing is limited to independent distribution channels where date-code authenticity and lot traceability must be verified at RFQ. For a BOM that already uses this part, the last-time-buy window has closed; any remaining stock is surplus inventory. A board-level redesign to a current Microchip MEMS oscillator (same DSC61XX family, different order code) is the typical migration path, though the exact pinout and output configuration must be confirmed against the new part's datasheet.
