Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the 0.197\" x 0.126\" footprint matches standard 5x3.2 mm oscillator land patterns, and the no-lead construction reduces parasitic inductance compared to a gull-wing package. The DSC1121 series is an established Microchip MEMS oscillator family; no pin-compatible second source is documented, but the wide supply range and standard footprint allow direct substitution with other 5x3.2 mm MEMS XOs from the same series.","metaTitle":"DSC1121BI5-050.0000T – 50 MHz MEMS XO, AEC-Q100, CMOS, 6-SMD","metaDescription":"Microchip DSC1121BI5-050.0000T: 50 MHz MEMS oscillator, ±10 ppm stability, 2.25V-3.6V supply, AEC-Q100 qualified, -40°C to 85°C.
