This frequency is a legacy telecom baud-rate multiple — common in UART clocking, serial-port controllers, and older modem or terminal equipment where a 1.8432 MHz crystal multiplied by 2.66 lands at 4.9152 MHz. No pin-compatible successor or official cross-reference is listed by Microchip for this part. A board-level redesign may be required to migrate to a current-production oscillator with the same frequency and package footprint. The 4-SMD, no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that reflows cleanly with standard lead-free profiles. The no-lead construction means the terminations are flush with the package edge; there is no exposed lead to inspect visually, so X-ray or boundary-scan is the only way to confirm solder-joint integrity after reflow. Under a hot-air station, the small thermal mass of this package means it heats quickly — a 300 °C nozzle at moderate airflow lifts the part in about 8–10 seconds without cooking adjacent components.","metaTitle":"DSC1033DI1-004.9152T XO 4.9152 MHz CMOS MEMS Oscillator -","metaDescription":"DSC1033DI1-004.9152T from Microchip Technology: XO (Standard) MEMS oscillator, 4.9152 MHz CMOS output, ±50 ppm stability, -40 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":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"4.9152 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","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 DSC1033DI1-004.9152T?","answer":"Microchip has not published a direct pin-compatible replacement or cross-reference for this obsolete order code.
