Product details

The DSC1033DI1-033.0000T is a 33 MHz XO (Standard) oscillator built on a MEMS resonator with CMOS output, operating from a 3.3V supply rail. It belongs to Microchip's PureSilicon™ series and is intended for surface-mount assembly in a compact 2.50mm x 2.00mm 4-SMD no-lead package.

A board-level redesign may be required to migrate to a current-production oscillator.

The 4-SMD no-lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm max. For always-on operation, connect this pin to Vdd or leave it floating if the datasheet specifies an internal pull-up.

Frequently asked questions

How can I order the DSC1033DI1-033.0000T or check availability?

This part is obsolete, so it is not stocked in active inventory. We source it through independent surplus channels on a quoted-to-order basis. Submit an RFQ with your target quantity and any date-code or lot requirements; we will confirm availability and pricing at quote time.

What is the replacement for DSC1033DI1-033.0000T?

Microchip has not published an official direct replacement for this exact ordering code. The DSC1033 series is discontinued. For a new design, consider a current-production MEMS oscillator from Microchip's newer families, such as the DSC1000 or DSC6000 series, but verify pinout, supply voltage, and frequency stability against your application.

What is the difference between DSC1033 and DSC1030?

Both are MEMS oscillators from Microchip's PureSilicon™ series, but the DSC1033 includes a standby (power-down) function, while the DSC1030 does not. The DSC1033's standby mode drops supply current to 1 µA maximum, which is the key differentiator for battery-powered or duty-cycled applications.
