Microchip lists the DSC1033CI1-001.9800 as Obsolete.
This is a fixed-frequency XO (Standard) generating a 1.98 MHz CMOS clock.
Operates on a 3.3V supply rail with ±50ppm frequency stability. The 4-SMD no-lead package measures 3.20mm x 2.50mm with a seated height of 0.90mm, a compact footprint for space-constrained boards.
Microchip has not published an official successor or pin-compatible cross-reference for this obsolete part. A board-level redesign with a different MEMS oscillator in the same 4-SMD package may be required. Confirm the frequency, supply voltage, and stability requirements before selecting an alternative.
