This is a MEMS-based XO (Standard) with CMOS output, 33.33 MHz, 3.3V supply, and ±50 ppm frequency stability. The 4-SMD no-lead package measures 2.50mm x 2.00mm, seated height 0.90mm — a common footprint for small-form-factor clock sources.
DSC1033DI1-033.3300T is obsolete and not available from Microchip directly. We source it through independent distribution channels — quantities are lot-specific and confirmed at RFQ. Submit a request with your target quantity and we'll quote against available inventory.
No direct pin-compatible successor is listed by Microchip for the DSC1033DI1-033.3300T. Any replacement will require evaluating the clock tree for frequency, voltage, stability, and package compatibility. A same-function MEMS oscillator from the DSC11xx or DSC60xx series may fit, but pinout and electrical characteristics must be verified against the original datasheet.
±50 ppm frequency stability over the operating temperature range.
Yes, the DSC1033DI1-033.3300T runs on 3.3V supply. Any replacement must also be 3.3V, match the 33.33 MHz frequency, and have the same package footprint. CMOS output and ±50 ppm or better stability are required to maintain timing margin.
