Product details

The DSC6003JI1A-012.0000: This is a Microchip DSC60XX series MEMS-based oscillator (XO, standard) that puts out a 12 MHz CMOS clock on a 1.71V–3.63V supply rail.

Obsolete — the sourcing reality for this BOM line

The 4-SMD no-lead footprint (2.50 mm x 2.00 mm) is common across many MEMS oscillators, so a functional swap may share the same PCB land pattern.

Temperature range and package — fit for the board

The ±50 ppm frequency stability is tight enough for a CAN or LIN node clock but not for a precision ADC reference. Surface-mount in a 4-SMD no-lead package, 0.098" x 0.079" footprint, 0.035" seated height — it fits a standard oscillator pad layout with no via-in-pad requirement.

Frequently asked questions

How can I order DSC6003JI1A-012.0000 or check availability?

This part is obsolete (Microchip no longer manufactures it), but we source it through independent surplus channels. Submit an RFQ with your target quantity — availability and pricing are confirmed per inquiry, not held as stock.

Is DSC6003JI1A-012.0000 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, meaning it was qualified for automotive stress and reliability requirements. That is the main reason a repair or legacy-production buyer would seek this exact order code rather than a commercial-grade substitute.

What is the replacement for DSC6003JI1A-012.0000?

No official replacement is listed by Microchip. For a pin-compatible cross, look at other MEMS oscillators in the same 2.50 mm x 2.00 mm 4-SMD package with CMOS output and 1.71V–3.63V supply — the DSC60XX series siblings may work but verify the frequency stability and enable polarity against your BOM.
