Product details

The DSC6001CE1A-044.2368T is a MEMS-based XO (standard oscillator) from Microchip's DSC60XX series, delivering a 44.2368 MHz CMOS output with enable/disable function. Rated AEC-Q100, it targets automotive applications where a quartz crystal's vibration sensitivity or startup time is a concern — the MEMS resonator handles shock and wide temperature gradients better than a bulk crystal. Supply voltage spans 1.71V to 3.63V, covering 1.8V, 2.5V, and 3.3V logic rails without an external regulator.

Microchip lists this part as Obsolete. No stock-holding claim; sourced per order.

Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm oscillator footprint that matches many quartz XO layouts.

Frequently asked questions

Is the DSC6001CE1A-044.2368T suitable for automotive applications?

Yes — it carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability stress tests. However, because it is obsolete, new automotive designs should migrate to an active MEMS oscillator from the same series or a quartz alternative with the same frequency and package.

What is a direct replacement for the DSC6001CE1A-044.2368T?

For a like-for-like swap, look for a 3.2 x 2.5 mm MEMS XO at 44.2368 MHz with CMOS output and AEC-Q100 rating from Microchip's active DSC60XX variants — confirm the supply voltage range and enable/disable function match your BOM.
