Product details

MEMS oscillator — 29.4912 MHz, CMOS, 3.3V

The DSC1033DI1-029.4912T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 29.4912 MHz CMOS output at 3.3V supply. Active draw is 3 mA typ at 29.4912 MHz.

Microchip lists the DSC1033DI1-029.4912T as Obsolete. No direct pin-compatible successor is named in the available records. A board-level redesign may be needed if a long-term supply is required.

Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm.

Frequently asked questions

What is the replacement for DSC1033DI1-029.4912T?

A functional replacement would require a different order code within the DSC1033 series or another MEMS oscillator with the same 29.4912 MHz frequency, CMOS output, 3.3V supply, and 4-SMD footprint — but a board spin may be needed to confirm compatibility.
