Obsolete MEMS oscillator – sourcing and replacement path
The DSC6001HI1A-032.7680T is officially classified as Obsolete by Microchip Technology. Available through independent distribution channels in lot-specific quantities.
Automotive-grade MEMS timing for existing designs
Rated AEC-Q100, this oscillator was designed for automotive environments where temperature cycling and vibration tolerance matter. The MEMS base resonator inherently resists shock better than a quartz crystal — useful in engine-bay or chassis-mounted ECUs. Operates from 1.71 V to 3.63 V with a typical supply current of 1.3 mA max, making it compatible with both 1.8 V and 3.3 V logic rails.
Housed in a 4-SMD no-lead package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm. The 0.50 mm pitch and small footprint are typical for space-constrained automotive modules.
