Product details

The DSC1003BI2-010.0000T: AEC-Q100 qualification means this part has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) required for under-hood and chassis-domain electronics — an engine control unit or transmission controller that sees 105°C ambient still has margin at the 85°C upper limit.

Standby function and supply range for battery-backed designs

The 4-SMD, no-lead package (5.00 mm × 3.20 mm footprint, 0.90 mm seated height) is a standard MEMS oscillator land pattern shared across the DSC1003 family — the same PCB footprint accepts any frequency variant in the series, simplifying BOM consolidation.

Frequently asked questions

What is the exact frequency of DSC1003BI2-010.0000T?

The oscillator outputs 10 MHz exactly, as indicated by the order code suffix -010.0000.

Is DSC1003BI2-010.0000T AEC-Q100 qualified?

Yes, the part carries AEC-Q100 ratings, meaning it has passed the automotive-grade qualification tests for temperature, reliability, and ESD — suitable for under-hood and chassis-domain applications.

Does DSC1003BI2-010.0000T have a standby/power-down function?

Yes, the function is listed as Standby (Power Down). When disabled, the supply current drops to 15 µA max, enabling low-power sleep modes in battery-operated or automotive systems.

What is the frequency stability of DSC1003BI2-010.0000T?

The frequency stability is ±25 ppm across the operating temperature range, which is typical for a MEMS oscillator and sufficient for most MCU clock trees and CAN/FlexRay timing.

Can DSC1003BI2-010.0000T be used as a replacement for DSC1003AI2-010.0000T?

The DSC1003AI2-010.0000T is a sibling variant in the same series — the 'BI2' suffix indicates a different temperature range or stability grade. Confirm the operating temperature and stability requirements of your design before substituting; the base frequency and package are identical.
