Product details

12.5 MHz MEMS XO — drop-in for quartz cans

It sits in a 4-SMD, no-lead package (3.20 mm x 2.50 mm footprint) and can replace a standard quartz oscillator of the same frequency without a board spin — the pinout and supply are the same.

Standby power-down — 1 µA disable current

That sub-microamp idle current makes this part a fit for battery-powered equipment that needs to wake a clock on demand without draining the cell during sleep.

Active lifecycle — orderable today

Microchip lists the DSC1033CE2-012.5000 as Active.

Frequently asked questions

Where can I buy DSC1033CE2-012.5000 and how is it quoted?

Submit an RFQ for a firm quote and lead-time estimate.

Can DSC1033CE2-012.5000 replace a standard quartz oscillator of the same frequency?

Yes — the DSC1033CE2-012.5000 is a MEMS-based XO with a standard CMOS output and 3.3 V supply, so it drops into a 4-pin SMD footprint designed for a quartz oscillator at 12.5 MHz. The MEMS resonator is more shock- and vibration-tolerant than quartz, which is a plus in portable or high-vibration applications.

What is the standby power-down current consumption of DSC1033CE2-012.5000?

In Standby (Power Down) mode, the maximum supply current is 1 µA. Normal operation draws up to 10 mA. The standby function disables the output and drops the active current by four orders of magnitude.

What is the closest pin-compatible alternative to DSC1033CE2-012.5000 in this Crystals & Oscillators family?

Within the DSC1033 series, any part with the same 4-SMD, no-lead package and 3.3 V supply is pin-compatible — the difference is frequency and stability grade. For a 12.5 MHz ±25 ppm XO, the DSC1033CE2-012.5000 is the direct entry; other frequency variants in the series share the same footprint.
