The -20°C~70°C operating temperature range is commercial-grade, so if the target ambient exceeds 70°C — for example, an engine-bay ECU — this part is not the fit; the industrial or extended range sibling in the DSC1001 family would be needed. Active draw is 7.2 mA max at 66.666 MHz — typical for a MEMS oscillator at this frequency and well within the budget of a 1.8 V to 3.3 V rail. The standby current is low enough that a coin-cell backup can hold the oscillator off without draining the battery during sleep. The 4-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The 0.276\" x 0.197\" footprint is standard for 7x5 mm oscillators and is pin-compatible with many quartz-based XOs, simplifying a drop-in replacement on existing layouts.","metaTitle":"DSC1001AE1-066.6660T MEMS XO – 66.666 MHz, AEC-Q100, Active","metaDescription":"Microchip DSC1001AE1-066.6660T: 66.666 MHz MEMS XO, CMOS output, AEC-Q100, standby function, -20°C~70°C, 4-SMD package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1001","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"66.666 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"7.2mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9450","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to DSC1001AE1-066.6660T?","answer":"Within the DSC1001 series, other frequency variants in the same 7x5 mm 4-SMD package share the same pinout. For a direct frequency match, no alternative order code is listed by Microchip — the DSC1001AE1-066.6660T is the only part at 66.666 MHz in this family. A quartz-based XO with the same footprint and frequency could serve as a functional equivalent, but pin compatibility must be verified against the specific quartz part's datasheet."},{"question":"Does DSC1001AE1-066.6660T have a standby function?","answer":"Yes. The standby (power-down) function disables the output and reduces supply current to 15 µA max.
