The -20°C lower limit means the oscillator is specified for indoor or conditioned environments; outdoor equipment exposed to -40°C should look at the DSC1033's industrial-temperature siblings. Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.50 mm pitch land pattern is common to many MEMS and quartz oscillators in the same footprint—verify the pad layout against your existing 4-pin oscillator land pattern; the no-lead package relies on a solder-paste stencil that matches the pad geometry, not through-hole leads.","metaTitle":"DSC1033CE1-008.0000 – 8 MHz MEMS XO, CMOS, 3.3 V, Active","metaDescription":"Microchip Technology DSC1033CE1-008.0000: 8 MHz MEMS oscillator, CMOS output, 3.3 V supply, ±50 ppm stability, active lifecycle.","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":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"8 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","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)":"3mA (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":"Is the DSC1033CE1-008.0000 RoHS compliant?","answer":"The evidence does not explicitly list RoHS compliance status. Microchip's PureSilicon™ series is generally RoHS-compliant, but confirm the specific date-code lot at RFQ if RoHS certification is required for your BOM."},{"question":"Can the DSC1033CE1-008.0000 replace a quartz oscillator?","answer":"Yes—the DSC1033 is a MEMS-based XO that drops into the same 4-SMD no-lead footprint as many quartz oscillators. The MEMS resonator offers faster startup (typically under 5 ms), better vibration immunity, and no quartz crystal aging drift. However, the ±50 ppm stability is looser than some high-end quartz XOs that guarantee ±25 ppm; check your system's timing budget before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033CE1-008.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033CE1-008.0000 when reusing this data.
