MEMS oscillator replacing a quartz can
Active production — no last-time-buy
Microchip lists the DSC1121CI2-066.6667T as Active. The 6-SMD no-lead package (3.20 mm × 2.50 mm, 0.90 mm seated height) is a standard MEMS oscillator footprint. It is pin-compatible with many quartz XO footprints of the same size — confirm the pad layout against your existing quartz oscillator before committing.
If your design is power-sensitive, the disable mode (22 mA max) helps during sleep states.
