Product details

The DSC1033BI1-012.0000T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 12 MHz CMOS output from a 3.3V supply rail. The 4-SMD, no-lead package measures 5.00mm x 3.20mm with a seated height of 0.90mm — a standard footprint that swaps onto most 12 MHz oscillator pads without a board spin.

Standby function and power draw

A Standby (Power Down) pin lets the system shut the oscillator off: max supply current is 3 mA typical when running, dropping to 1 µA in disable — useful for battery-powered designs that need to wake on an external event.

Microchip lists the DSC1033BI1-012.0000T as Obsolete. Available through independent surplus channels in lot-specific quantities. A quote against your BOM line confirms current availability and pricing — no stock-holding claim is made here.

Frequently asked questions

Is DSC1033BI1-012.0000T compatible with 3.3V logic?

Yes. The oscillator runs on a 3.3V supply and outputs CMOS levels, so it drives 3.3V logic inputs directly without a level shifter.

What is the closest pin-compatible alternative to DSC1033BI1-012.0000T?

No official pin-compatible replacement is listed by Microchip. The DSC1033 series shares the same 4-SMD footprint and 3.3V supply, but a specific frequency and stability variant must be verified against the BOM. A cross-reference search at RFQ can identify active siblings in the series.
