Microchip lists the DSC1033BI1-004.0000 as Obsolete. For a new design, consider the active DSC1033 family siblings in the same 4-SMD no-lead package. The 'CI1' suffix variant (DSC1033CI1-004.0000) shares the same 4 MHz frequency, 3.3V supply, and CMOS output but may carry a different stability grade or temperature range — verify the datasheet before substituting.","metaTitle":"DSC1033BI1-004.0000 MEMS Oscillator 4 MHz CMOS - Microchip","metaDescription":"DSC1033BI1-004.0000 XO (Standard) from Microchip. 4 MHz, CMOS output, 3.3V, ±50ppm stability, -40°C to 85°C.
