Standby (Power Down) function on pin 1 drops supply current to 1 µA max, useful for battery-powered designs that need to gate the clock tree during sleep. Available through independent surplus channels; quantities are lot-specific and confirmed at RFQ. No official successor or pin-compatible replacement is listed by Microchip. ## Package and mounting — 4-SMD no-lead Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many 5x3.2 mm oscillator footprints. Surface-mount assembly; the no-lead package requires a solder-paste stencil aperture that matches the pad layout in the datasheet — no via-in-pad needed.","metaTitle":"DSC1033BI2-050.0000T MEMS Oscillator 50 MHz CMOS Obsolete","metaDescription":"DSC1033BI2-050.0000T XO (Standard) MEMS oscillator, 50 MHz CMOS, 3.3V, ±25ppm, -40°C to 85°C.
