12 MHz MEMS oscillator — obsolete, sourced on request
The DSC6011JI1A-012.0000: AEC-Q100 qualification places it in the automotive-grade bucket — the MEMS resonator and CMOS ASIC are screened to the same reliability and temperature stress standards as the rest of the car's electronics. Microchip has marked this part obsolete. Sourcing runs through independent distribution — quantities, date codes, and pricing confirmed at RFQ against your BOM line.
Sourcing an obsolete MEMS oscillator
With the product status set to Obsolete, the DSC6011JI1A-012.0000 is no longer manufactured by Microchip. No pin-compatible direct replacement is listed in the official lifecycle record. For an existing design that already qualified this part, the sourcing path is the spot market — independent brokers and surplus channels hold remaining inventory. Lot traceability and authenticity screening are confirmed at quote time. For a new design, a functional equivalent from the same DSC60XX family or a different MEMS oscillator vendor should be evaluated; the 2.5x2.0 mm 4-SMD footprint and 1.71-3.63 V supply range are common in the MEMS oscillator space, so a board respin may not be required if the replacement matches the pinout and control logic.
