Microchip lists this part as obsolete. That means the factory line has stopped; any remaining stock is what independent distribution holds. For a storeroom keeper, this is a last-time-buy candidate if the line still needs it — once the reels are gone, there is no more from the original source. ## AEC-Q100 and the automotive temperature envelope Rated AEC-Q100, this oscillator passed the automotive IC qualification stress tests: high-temperature operating life, temperature cycling, and ESD robustness. If the application sees sustained 105°C or higher, this part is not the right fit. ## Supply flexibility and board-fit footprint Tape & Reel packaging is the usual for automated assembly. Typical supply current is 3 mA while oscillating — low enough for battery-backed real-time clock references but not ultra-low-power.","metaTitle":"Microchip DSC6101CI1A-066.6670T XO, 66.667 MHz, CMOS","metaDescription":"Microchip DSC6101CI1A-066.6670T XO (Standard), 66.667 MHz CMOS output, MEMS resonator, AEC-Q100, -40°C~85°C.
