It replaces a quartz crystal oscillator in the same footprint — the MEMS resonator eliminates quartz start-up time and is less sensitive to vibration and shock. ## Package, footprint, and reflow fit Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The 0.098\" x 0.079\" land pattern matches standard 4-pad oscillator footprints — no special fan-out or via-in-pad required. For outdoor telecom enclosures or under-hood applications that see -40°C or +85°C, a wider-grade part from the DSC1033 family would be needed. Product status is Active per Microchip's current lifecycle record.","metaTitle":"DSC1033DE1-066.0000T – Microchip MEMS XO, 66 MHz, CMOS, 3.3V","metaDescription":"Active-production MEMS oscillator from Microchip's PureSilicon™ series. 66 MHz, CMOS output, 3.3V supply, ±50 ppm stability, 4 mA typ supply. 4-SMD package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1033, PureSilicon™","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"66 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"3.3V","Base Product Number":"DSC1033","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"4mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can DSC1033DE1-066.0000T replace a standard quartz oscillator?","answer":"Yes — the DSC1033 is a MEMS-based XO that is footprint-compatible with many 4-pad quartz oscillators in the same 2.5 mm x 2.0 mm package. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, and it starts up faster (no crystal start-up time). The output is CMOS, the supply is 3.3V, and the frequency stability is ±50 ppm — all within the range of a standard quartz XO. Confirm the pinout and enable logic (standby function) against your existing quartz part's datasheet before substituting."},{"question":"Is DSC1033DE1-066.0000T obsolete?","answer":"No — the product status is listed as Active.
