Housed in a 6-SMD, No Lead package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — a standard footprint that matches many quartz oscillators, so a layout designed for a 7x5 mm can often accept this MEMS part without a board spin. No direct pin-compatible replacement is listed, but the DSC1124 series shares the same footprint and supply range across multiple frequencies.","metaTitle":"DSC1124NI1-156.2500 MEMS XO 156.25 MHz HCSL - Microchip","metaDescription":"DSC1124NI1-156.2500: Microchip MEMS oscillator, 156.25 MHz, HCSL output, ±50 ppm, -40°C to 85°C, 6-SMD.
