Product details

The DSC1001DI2-027.3750T: AEC-Q100 rated — this part is qualified for automotive applications, meaning it has passed the stress tests and reliability requirements for under-hood or cabin electronics.

Standby mode cuts supply to 15 µA

A dedicated standby (power down) function drops the maximum supply current from 7.2 mA to 15 µA — useful for battery-powered modules that need to wake the system clock on demand without a separate enable signal.

Wide supply range and small 4-SMD footprint

Operates from 1.8 V to 3.3 V, covering the common logic rails without an external regulator. Housed in a no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm.

Frequently asked questions

Can DSC1001DI2-027.3750T replace a standard crystal oscillator?

Yes — it is a drop-in replacement for a quartz-based oscillator in the same 4-SMD footprint, but with MEMS reliability, wider supply range (1.8 V–3.3 V), and AEC-Q100 qualification that a standard crystal typically lacks.

Does DSC1001DI2-027.3750T have a standby mode?

Yes — the function is listed as Standby (Power Down), and the maximum supply current when disabled is 15 µA.
