The DSC6003JI2A-010.0000T: This is a 10 MHz MEMS-based oscillator from Microchip's DSC60XX series, delivering a CMOS output with ±25 ppm frequency stability across the full -40°C to +85°C industrial temperature range. Rated AEC-Q100, it was designed for automotive-grade applications where shock and vibration tolerance matter more than a quartz-based XO can offer — the MEMS resonator handles 50,000 g shock without frequency shift.
The DSC6003JI2A-010.0000T is officially obsolete per Microchip's product status. There is no direct pin-compatible replacement listed by the manufacturer; the DSC60XX family has been superseded by newer MEMS oscillator series. No last-time-buy window remains open from the factory.
Operates from 1.71V to 3.63V supply, drawing 1.3 mA typical at 10 MHz — suitable for low-power embedded clocks in battery-backed or 3.3V/1.8V dual-rail systems. Housed in a 2.50 mm x 2.00 mm 4-SMD no-lead package with a seated height of 0.89 mm.
