Microchip lists the DSC1033AE1-050.0000T as obsolete. For a new design, consider the active DSC1000 series from Microchip, which shares the same 4-SMD package and 3.3V supply but uses a different MEMS die — pin compatibility should be verified against the datasheet before committing a board spin. ## Package and mounting — 4-SMD no-lead exposed pad The 4-SMD, no-lead exposed pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Reflow profile follows standard JEDEC J-STD-020 for MSL level 1, so no bake is needed before assembly if the reel seal is intact.","metaTitle":"DSC1033AE1-050.0000T MEMS XO Oscillator 50 MHz CMOS Obsolete","metaDescription":"Microchip DSC1033AE1-050.0000T MEMS XO (Standard) oscillator, 50 MHz CMOS output, ±50 ppm stability, 3.3V supply, -20°C~70°C.
