Product details

MEMS oscillator with AEC-Q100 pedigree

AEC-Q100 qualification means this is a documented automotive-grade part—the OEM auditor will see PPAP-ready data, not a commercial oscillator dressed up for the engine bay.

Runs from 2.5 V to 3.3 V, covering the common logic rails for automotive microcontrollers and Ethernet PHYs without an extra regulator.

Housed in a 6-VDFN package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm—compatible with standard reflow profiles and bottom-side clearance constraints.

Sourced through independent distribution per RFQ.

Frequently asked questions

Where can I buy DSC1221NE3-38M00000T?

We source this active Microchip MEMS oscillator to order. Submit an RFQ with your target quantity—we will confirm current pricing and lead time from our distribution network.

Is DSC1221NE3-38M00000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating. That means it meets the automotive stress and reliability requirements—temperature cycling, ESD, latch-up—with documentation an OEM auditor expects.

Is there a replacement or equivalent for DSC1221NE3-38M00000T?

No pin-compatible second-source is documented from another manufacturer. Within the DSC12X1 family, other frequency variants share the same footprint and supply range.
