Microchip lists the DSC1033BI1-048.4610 as Obsolete. A board-level redesign to a current MEMS oscillator family (e.g., DSC1001 or DSC1121 series) may be the more sustainable path for new production. ## Temperature range and package — board-fit note The 4-SMD, No Lead package (5.00 mm × 3.20 mm footprint, 0.90 mm seated height) is a standard surface-mount form factor; the PCB land pattern matches common MEMS oscillator layouts, so a replacement from another vendor with the same package outline can drop in without board changes. ## Frequency stability and supply current","metaTitle":"DSC1033BI1-048.4610 MEMS Oscillator 48.461 MHz CMOS Obsolete","metaDescription":"Microchip DSC1033BI1-048.4610 XO (Standard) MEMS oscillator, 48.461 MHz, CMOS output, ±50ppm, -40°C to 85°C, 3.3V.","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":"48.461 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","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 DSC1033BI1-048.4610?","answer":"Microchip has not published a direct pin-compatible replacement for this specific frequency and package. For new designs, consider the DSC1001 or DSC1121 series from Microchip, which offer similar MEMS oscillator performance in the same 4-SMD package — confirm the frequency, supply voltage, and stability grade against your timing budget."},{"question":"Does DSC1033BI1-048.4610 have a standby function?","answer":"Yes. The standby (power-down) function disables the output and drops supply current to 1 µA max. The oscillator stops; the output goes high-impedance. This is controlled by a dedicated pin on the device."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033BI1-048.4610","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033BI1-048.4610 when reusing this data.
