Product details

The DSC6001CI2A-004.0000 is a 4 MHz MEMS-based XO with CMOS output, rated for the -40°C to 85°C automotive temperature range and AEC-Q100 qualified — originally intended for under-hood or cabin timing where crystal shock resistance was a concern. Microchip has marked this part obsolete (productStatus: Obsolete).

Supply rails and stability for bus timing

Operates from 1.71 V to 3.63 V supply — covers 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator. The ±25 ppm frequency stability over temperature keeps a CAN or LIN bus within the 1.5% bit-time tolerance budget across the automotive range.

Frequently asked questions

What is the recommended replacement for DSC6001CI2A-004.0000?

Microchip does not list a direct pin-compatible successor for this exact frequency and grade. The DSC60XX family includes active 4 MHz variants, but their AEC-Q100 qualification, package code, and stability grade may differ. A cross-reference search against the original BOM requirements (automotive temp, ±25 ppm, 4 MHz, 4-SMD) is needed to identify a drop-in candidate.

Is the DSC6001CI2A-004.0000 rated for automotive (AEC-Q100) applications?

Yes, the part carries an AEC-Q100 rating, meaning it passed the automotive-grade stress tests (temperature cycling, ESD, latch-up) and is suitable for under-hood or cabin electronics where the ambient temperature stays within -40°C to 85°C.
