MEMS oscillator for 33 MHz clocking
Supply voltage is 3.3 V, and the part draws just 3 mA typical during active operation.
Industrial temperature and small footprint
The 0.90 mm seated height keeps it low-profile for compact enclosures.

Frequently asked questions
Can the DSC1033BI2-033.0000T replace a quartz oscillator of the same frequency?
Yes, in most cases. The DSC1033BI2-033.0000T is a MEMS-based XO that is pin-compatible with many standard 33 MHz quartz oscillators in the 5.00 mm × 3.20 mm 4-SMD footprint. The MEMS resonator offers better shock and vibration immunity and faster startup than quartz, but the electrical interface (CMOS output, 3.3 V supply) is the same. Verify the enable/standby logic polarity matches your design — the DSC1033 uses a Standby (Power Down) function.
What is the standby current of the DSC1033BI2-033.0000T?
Maximum supply current in Standby (Power Down) mode is 1 µA. Active current is 3 mA typical.
Is the DSC1033BI2-033.0000T RoHS compliant?
The evidence does not explicitly list RoHS compliance status. Confirm with the datasheet or your Microchip representative. The part is lead-free in the 4-SMD package, but formal RoHS certification should be verified.
