Standby (Power Down) function drops supply current to 1 µA max, letting the oscillator sleep between active periods without a separate enable signal. It is available through independent distribution in lot-specific quantities, confirmed at RFQ. No official successor or pin-compatible replacement is listed by Microchip for the DSC1033CI1-033.0000. A board-level redesign using a current-production MEMS or quartz oscillator in the same 4-SMD, No Lead footprint is the typical migration path. ## Package and footprint for board layout Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts typical of handheld or space-constrained designs. The 3.3 V supply rail and 3 mA typical current draw keep the thermal budget low, so no special copper pour or via stitching is needed around the oscillator.","metaTitle":"DSC1033CI1-033.0000 – Microchip MEMS XO, 33 MHz, CMOS","metaDescription":"DSC1033CI1-033.0000 is a 33 MHz MEMS XO with CMOS output, ±50 ppm stability, -40°C to 85°C range.","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":"33 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)":"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":"What is the replacement for the DSC1033CI1-033.0000?","answer":"Microchip has not published an official successor for this exact order code.
