The DSC1033AI2-033.3333T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 33.3333 MHz CMOS output from a 3.3V rail.
The 4-SMD, No Lead Exposed Pad package (7.00 mm x 5.00 mm footprint, 0.90 mm seated height) is standard for MEMS oscillators of this generation — a replacement from another vendor with the same pinout and supply voltage may fit without a board spin.
No official direct replacement is listed. A MEMS oscillator from the same DSC1033 family with the same 4-SMD footprint, 3.3V supply, and CMOS output may drop in — but the standby function and ±25 ppm stability must be verified against your application's timing budget. Cross-reference at RFQ.
