Product details

The DSC1001CI1-004.0000T is a 4 MHz MEMS-based oscillator (XO) with CMOS output, rated across -40°C to 85°C and qualified to AEC-Q100 — meaning it handles the thermal cycling and vibration profile of an engine-bay ECU or a factory-floor PLC without the start-up reliability concerns of a quartz crystal.

Package, footprint, and layout reuse

Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the same footprint used by many MEMS oscillators from SiTime, Abracon, and Epson, so a single PCB pad pattern can serve multiple second-source options. Surface-mount only; the 0.90 mm profile fits under low-clearance shields or in slim enclosures.

Active lifecycle — no design-in risk

Frequently asked questions

What is the closest pin-compatible alternative to DSC1001CI1-004.0000T?

Any 4 MHz MEMS oscillator in the 3.2x2.5 mm 4-SMD package with CMOS output and a 1.8-3.3 V supply range is footprint- and function-compatible. The SiTime SiT1602B series and Abracon AMPM series are common cross-shopped families — same package, same supply, same output type. Confirm the frequency stability and temperature grade match your BOM before swapping.

Can a MEMS oscillator replace a crystal oscillator?

Yes, if the load expects a CMOS clock input rather than a crystal resonator. The DSC1001 outputs a rail-to-rail CMOS square wave at 4 MHz with ±50 ppm stability — it drives the clock input of an MCU or SoC directly, no external load capacitors or feedback resistor needed. MEMS oscillators also tolerate higher shock and vibration than quartz crystals.
