The 4-SMD no-lead package (2.50 mm x 2.00 mm, 0.90 mm seated height) is a common footprint for compact PCB layouts — the MEMS resonator eliminates the quartz crystal's mechanical sensitivity, so the oscillator tolerates vibration and shock better than a traditional crystal can.
No stock-holding claim — each lot is sourced per request.
Microchip has not published an official successor or pin-compatible cross-reference for the DSC1033DI1-033.0000. A replacement evaluation is needed — the 33 MHz frequency, CMOS output, 3.3 V supply, and 4-SMD no-lead footprint are the key parameters to match. The MEMS base resonator means a quartz-based substitute may have different vibration and aging characteristics.
