Microchip lists the DSC1033DI1-014.3181T as obsolete. Availability is confirmed at RFQ — there is no guaranteed stock. If your BOM requires a 14.3181 MHz MEMS XO in a 2.5 mm × 2.0 mm 4-SMD package, a board spin may be needed to accommodate an alternative oscillator from the DSC1033 series or another vendor. The 4-SMD no-lead package measures 0.098\" × 0.079\" (2.50 mm × 2.00 mm) with a seated height of 0.035\" (0.90 mm). Surface-mount placement on a standard 4-pad land pattern — no external load capacitors required for the MEMS resonator. The small footprint suits space-constrained PCBs in portable or densely populated designs.","metaTitle":"DSC1033DI1-014.3181T Microchip MEMS XO 14.3181 MHz CMOS","metaDescription":"Microchip DSC1033DI1-014.3181T MEMS XO, 14.3181 MHz, CMOS output, 3.3V, ±50 ppm, -40°C to 85°C.
