It draws 6.3 mA max in active mode and just 15 µA in standby (power-down), so it fits battery-backed modules or always-on ECUs that sleep between wake cycles. The supply voltage spans 1.8V to 3.3V, covering common 2.5V and 3.3V logic rails without a separate regulator — one part number for multiple board variants.
Yes — it is a MEMS-based oscillator in a standard 4-SMD, no-lead package that is pin-compatible with many quartz oscillators. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, making it a better fit for automotive and industrial applications.
The standby (power-down) current is 15 µA max, while the active supply current is 6.3 mA max.
Yes — the supply voltage range is 1.8V to 3.3V, so it works directly on 3.3V logic rails without a level shifter.

Within the DSC1001 series, other frequency variants share the same 4-SMD, no-lead footprint and pinout — only the frequency and stability grade differ. For a direct frequency match, the DSC1001BI2-025.0000T is the standard ±25 ppm version; the DSC1001BI2-025.0000 (without 'T' suffix) is the same part in a different reel quantity.
