Product details

No stock-holding claim is made; availability is verified per inquiry.

AEC-Q100 qualification and automotive fit

Rated AEC-Q100, the DSC6003CI1A-033.0000 was designed for automotive-grade reliability — the -40°C to +85°C operating range covers cabin and chassis-mounted electronics.

33 MHz CMOS output with wide supply range

Fixed 33 MHz output in CMOS logic levels, with a supply voltage range of 1.71V to 3.63V — this covers 1.8V, 2.5V, and 3.3V logic rails without an external level translator.

Package and board layout notes

Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The small footprint suits space-constrained automotive ECUs and sensor modules.

Frequently asked questions

Is the DSC6003CI1A-033.0000 obsolete?

Yes, Microchip has classified this part as Obsolete. There is no official successor or pin-compatible replacement from Microchip. For existing designs, the part can be sourced through independent surplus channels — quantities are confirmed at RFQ. If you are starting a new design, look at Microchip's current DSC60XX series MEMS oscillators in the same package and frequency, but verify pin compatibility and electrical specs against your BOM.

What is the replacement for DSC6003CI1A-033.0000?

Microchip has not published a direct replacement for this order code. The DSC60XX series includes active variants with the same 4-SMD package and 33 MHz frequency, but the exact order code suffix (temperature range, stability, enable function) must be matched. A cross-reference search against the DSC6003 family is recommended — confirm the supply voltage (1.71V–3.63V) and AEC-Q100 rating if automotive qualification is required.

Is the DSC6003CI1A-033.0000 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, meaning it was qualified for automotive-grade reliability under the stress and temperature requirements of that standard. This includes the -40°C to +85°C operating temperature range.
