Microchip lists the DSC1033BE1-050.0000 as Obsolete. The 4-SMD, No Lead package is common across the DSC1033 family, so a pin-compatible sibling from the same series may substitute if the frequency and stability match.","metaTitle":"DSC1033BE1-050.0000 MEMS Oscillator – 50 MHz, CMOS, Obsolete","metaDescription":"Microchip DSC1033BE1-050.0000 XO (Standard), 50 MHz CMOS output, ±50 ppm stability, 3.3 V, -20°C~70°C.
