Product details

What this MEMS oscillator brings to your board

The DSC6003JI1B-012.0000 is a 12 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC60XXB series, delivering a CMOS output from a 1.8V to 3.3V supply rail. At 1.3 mA typical current draw, it's a low-power clock source for always-on or battery-backed domains.

AEC-Q100 grade and temperature range

The industrial temperature range covers the full automotive cabin and most outdoor industrial gear without derating.

Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, it's a compact surface-mount footprint. No exposed thermal pad to worry about; just standard decoupling on the supply pin.

Frequently asked questions

Is the DSC6003JI1B-012.0000 automotive qualified?

Yes, it carries an AEC-Q100 rating, meaning it meets automotive IC qualification standards for temperature, reliability, and PPAP. It's suited for under-hood and cabin applications within its -40°C to 85°C operating range.

What is the output type and frequency of this oscillator?

It outputs a CMOS square wave at 12 MHz. The CMOS logic level tracks the supply voltage (1.8V to 3.3V), so it interfaces directly with most MCU clock inputs without level shifting.

Can I use the DSC6003JI1B-012.0000 as a direct replacement for an Epson SG-210STF 12 MHz?

Both are 12 MHz XO oscillators with CMOS output, but the package and pinout differ — the DSC6003JI1B uses a 4-VLGA footprint, while the SG-210STF is a different package. A direct drop-in replacement is not guaranteed without checking the PCB land pattern and pin assignments. Verify compatibility against your board layout before committing.

What is the frequency stability of the DSC6003JI1B-012.0000?

It's specified at ±50 ppm, which includes variations over the full -40°C to 85°C temperature range, supply voltage, and aging. For a 12 MHz clock, that's a maximum drift of ±600 Hz — tight enough for most MCU and CAN bus timing requirements.
