Product details

The DSC1001BI1-012.5000 is a 12.5 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, qualified to AEC-Q100 — the automotive IC reliability standard. The supply voltage range of 1.8V to 3.3V covers the common digital core rails — a single part serves 1.8V, 2.5V, or 3.3V logic without a separate regulator.

Compare that to the 6.3 mA max draw during active oscillation.

Package, footprint, and temperature grade

Housed in a 4-SMD, no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm. The 0.197" × 0.126" footprint matches the industry-standard 5×3.2 mm oscillator land pattern — no board layout change from a quartz XO of the same size.

Listed as Active by Microchip. This is a current-production part that can be ordered against a BOM without worrying about a forced redesign.

Frequently asked questions

Is the DSC1001BI1-012.5000 RoHS and AEC-Q100 compliant?

Yes, the part carries AEC-Q100 qualification, which includes RoHS compliance as part of the automotive-grade material declaration. No separate RoHS certificate is needed for most BOM audits — the AEC-Q100 report covers it.

What is the standby current of the DSC1001BI1?

The maximum supply current in standby (power down) mode is 15 µA. This is the current drawn when the enable pin disables the oscillator output; the input supply rail must still be present.
