No pin-compatible second source or official successor is documented — the DSC1001 series is the sole reference. For a direct alternative, confirm the BOM position package and frequency tolerance before substituting. ## MEMS base resonator — no quartz aging curve The ±25 ppm stability is specified across the full temperature range, not just at 25 °C. The disable current of 15 µA supports wake-on-event architectures without a dedicated power switch.","metaTitle":"DSC1001CI2-012.5000T 12.5 MHz MEMS XO, AEC-Q100, CMOS, 4-SMD","metaDescription":"DSC1001CI2-012.5000T: 12.5 MHz MEMS-based XO, AEC-Q100 qualified, CMOS output, 1.8-3.3 V supply, active production.

However, the MEMS die has different supply-current and start-up characteristics than a quartz oscillator. Verify the supply voltage range (1.8-3.3 V), package footprint (3.20 mm x 2.50 mm 4-SMD), and output drive strength against your existing oscillator before substituting."},{"question":"What is the frequency tolerance of DSC1001CI2-012.5000T?","answer":"Frequency stability is ±25 ppm across the -40 to +85 °C operating range.
