The DSC1018DI2-025.0000T is a 25 MHz MEMS-based XO (Standard) with a CMOS output and a Standby (Power Down) function — the MEMS resonator eliminates quartz start-up variability and the standby pin drops supply current to 1 µA max, making it a fit for battery-operated or intermittently-powered systems where the clock tree must shut down between active periods.
The evidence does not list a direct replacement relationship. Both are 25 MHz MEMS XOs in the same package and supply voltage, but the DSC1018 series includes the Standby (Power Down) function — confirm the pinout and control logic against the DSC1001 datasheet before substituting.
Yes — the Standby (Power Down) function is listed. When the standby pin is asserted, the oscillator draws 1 µA max supply current, stopping the output and reducing power consumption to near-zero for battery or energy-harvesting applications.
