Product details

The MEMS base resonator inherently resists vibration and mechanical shock better than quartz, which is why this series is specified for engine-control units, ADAS sensors, and infotainment modules that see constant vibration.

The supply range spans 1.8V to 3.3V, so the same part can run from a 1.8V core rail or a 3.3V I/O rail without a separate level translator — simplifies BOM consolidation across multiple voltage domains.

Package and footprint for automated assembly

Housed in a 4-SMD, no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm — a compact footprint that matches standard 2.5 x 2.0 mm oscillator land patterns, so no board spin is needed if replacing a quartz oscillator of the same size.

Frequently asked questions

Can DSC1001DI5-007.3728 replace a standard 7.3728 MHz quartz oscillator?

Yes, if the board's oscillator footprint is a 4-pad 2.5 x 2.0 mm no-lead pattern. The MEMS oscillator is a drop-in replacement for a quartz oscillator of the same package size and output type (CMOS). The ±10 ppm stability is tighter than typical ±25 ppm quartz, so the timing margin improves. No external load capacitors are needed — the MEMS resonator is self-contained.

Is DSC1001DI5-007.3728 AEC-Q100 qualified?

Yes, the part carries AEC-Q100 ratings, which means it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. This qualifies it for under-hood and cabin applications where standard commercial oscillators would not be acceptable.
