AEC-Q100 qualification means this part has passed the automotive-grade reliability stress tests — temperature cycling, biased humidity, and ESD — required for under-hood and cabin ECUs. The Enable/Disable function allows the output to be tri-stated, cutting supply current from 35 mA max to 22 mA max — useful for power-cycled subsystems or test modes where the clock must be gated without removing the supply. There is no announced end-of-life or NRND notice, so the part is available for both new designs and ongoing production without a last-time-buy window. Sourced through independent distribution, this oscillator is quoted to order against the BOM quantity. ## 6-SMD package and footprint fit The 6-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Surface-mount mounting suits automated pick-and-place assembly. The 35 mA max supply current is well within the capacity of a typical 3.3 V rail, so no additional bulk decoupling is needed beyond the standard 0.1 µF ceramic at the supply pin.","metaTitle":"DSC1121AI5-125.0032T MEMS Oscillator","metaDescription":"Microchip DSC1121AI5-125.0032T XO (Standard) MEMS oscillator, 125.0032 MHz CMOS output, ±10 ppm stability, 2.25-3.6 V supply, AEC-Q100 qualified.","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":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"125.0032 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-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":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1121AI5-125.0032T AEC-Q100 qualified?","answer":"Yes, the DSC1121AI5-125.0032T carries an AEC-Q100 rating, which qualifies it for automotive-grade applications including under-hood and chassis-mounted ECUs where temperature cycling and vibration are factors."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121AI5-125.0032T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121AI5-125.0032T when reusing this data.
