The MEMS base resonator gives it shock and vibration tolerance compared to quartz — relevant for industrial or portable equipment that sees mechanical stress. The standby (power-down) function drops supply current to 1 µA max — the oscillator's own draw is negligible when the system sleeps, making it suitable for battery-powered sensors or IoT nodes that wake intermittently. Microchip lists the DSC1033CI1-050.0000 as Obsolete. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. A board spin would be required to migrate to a current-production oscillator; the 4-SMD no-lead footprint and 3.3 V supply are common, but the MEMS vs quartz difference may affect jitter and startup timing in the target circuit. The 4-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts. The no-lead construction requires a solder-paste stencil aperture matched to the pad geometry; typical land pattern follows the JEDEC standard for this body size.","metaTitle":"DSC1033CI1-050.0000 MEMS Oscillator – 50 MHz, CMOS, Obsolete","metaDescription":"Microchip DSC1033CI1-050.0000 XO (Standard) MEMS oscillator, 50 MHz CMOS output, ±50 ppm stability, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1033, PureSilicon™","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"50 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°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":"What is the replacement for DSC1033CI1-050.0000?","answer":"No pin-compatible replacement is documented by Microchip.
