Product details

33.33 MHz MEMS oscillator for industrial timing

The MEMS resonator replaces a quartz crystal — no crystal selection, no load-cap tuning, and faster startup than a quartz oscillator in the same footprint.

Active production — no LTB window to track

Listed as Active by Microchip — no end-of-life notice, no last-time-buy deadline.

Standby power-down and small 4-SMD package

Includes a Standby (Power Down) function — when disabled, the supply current drops to 1µA max, preserving battery life in duty-cycled or portable designs. Housed in a 2.50mm x 2.00mm 4-SMD, No Lead package, 0.90mm seated height — fits tight PCB layouts where a standard 3.2mm x 2.5mm quartz oscillator would not.

Frequently asked questions

What is the exact frequency of DSC1033DI1-033.3300?

33.33 MHz.

What is the closest pin-compatible alternative in the DSC1033 family?

The DSC1033 series includes other frequency variants in the same 4-SMD package and 3.3V supply — for example, a 25 MHz or 50 MHz version shares the same pinout. Confirm the exact frequency needed; the base product number DSC1033 covers the family.
