Product details

The MEMS resonator construction inherently resists 50,000 g shock and 70 g vibration, which is why this part is often specified for engine control units, transmission controllers, and ADAS sensor modules.

Supply voltage and standby power budget

The supply voltage range of 1.8V to 3.3V covers the three most common digital rails — a single BOM line can serve 1.8V, 2.5V, or 3.3V domains without a separate level translator. Active current is 7.2 mA max at 27 MHz; when the Standby (Power Down) pin is asserted, the disable current drops to 15 µA max — this 480× reduction lets the system sleep for days on a coin cell while keeping the oscillator ready to wake on a threshold event.

Package and PCB layout notes

The 4-pin footprint is compatible with standard quartz oscillator layouts, so a board originally designed for a quartz XO can often accept this MEMS part without a respin — confirm the pin 1 orientation and the disable pin mapping against the existing footprint.

No official second source or direct replacement is published — the DSC1001 series is the only family carrying this exact frequency and grade combination.

Frequently asked questions

Does DSC1001AI2-027.0000 support a 1.8V supply?

Yes, the supply voltage range is 1.8V to 3.3V, so it operates directly on a 1.8V rail without an external regulator.

What is the standby mode current consumption?

When the Standby (Power Down) function is active, the disable current is 15 µA max — a 480× reduction from the 7.2 mA active current.

Is DSC1001AI2-027.0000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating, meaning it has passed automotive-grade reliability testing for temperature, ESD, and mechanical stress.
