It operates from a 1.71V to 3.63V supply, drawing 1.3 mA typical, and is qualified to AEC-Q100 — suited for automotive cabin or under-hood modules that require a stable clock source across temperature. The 4-SMD no-lead package (1.6 mm x 1.2 mm footprint) is a common MEMS oscillator land pattern, compatible with standard reflow profiles for surface-mount assembly. ## Obsolete status and sourcing path A functional replacement would require a MEMS oscillator in the same 4-SMD package with matching 18.432 MHz frequency, CMOS output, and 1.71V–3.63V supply range — but the standby function and AEC-Q100 rating must be verified per the new part's datasheet. ## Supply voltage and temperature compatibility The 1.71V to 3.63V supply range directly covers 3.3V and 2.5V rails — no external level translation needed for the oscillator power pin.","metaTitle":"DSC6001HE1A-018.4320 MEMS XO Oscillator – Microchip","metaDescription":"DSC6001HE1A-018.4320 is an obsolete MEMS XO oscillator from Microchip. 18.432 MHz, CMOS output, AEC-Q100 rated.","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":"DSC60XX","Package":"Bag","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"18.432 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.063\\\" L x 0.047\\\" W (1.60mm x 1.20mm)","Voltage - Supply":"1.71V ~ 3.63V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.89mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"1.3mA (Typ)","Absolute Pull Range (APR)":"±50ppm","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f42caf3e07022c4d06d7c884f387c56e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC6001HE1A-018.4320 compatible with a 3.3V supply?","answer":"Yes.
