Product details

The DSC1001CI5-074.2500T: The AEC-Q100 rating means it passed automotive-grade qualification — temperature cycling, ESD, and reliability stress — but the temperature grade tops out at 85°C, so it fits cabin or body-domain modules, not the engine bay.

Standby power-down and current draw

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 standard 3.2 x 2.5 mm MEMS oscillator footprint, compatible with most reflow profiles and no via-in-pad required.

Microchip Technology is the sole manufacturer.

Frequently asked questions

Does DSC1001CI5-074.2500T have a standby mode?

Yes, the function is Standby (Power Down). When enabled, the supply current drops to 15 µA max, letting the oscillator be gated off in low-power system states.

Is DSC1001CI5-074.2500T RoHS compliant?

The part is listed as RoHS compliant per Microchip's standard material declaration for the DSC1001 series. No conflict with current RoHS exemptions.

What is the difference between DSC1001 and DSC1004?

The DSC1001 is a standard XO with CMOS output. The DSC1004 is a different series in the same MEMS family — typically a different output type or feature set. For a pin-compatible alternative within the same family, check the DSC1001 base number; the DSC1004 would require a separate datasheet review.
