Its AEC-Q100 qualification means it passes the temperature, reliability, and PPAP requirements for automotive electronics — suitable for infotainment, ADAS sensor clocks, or body-controller timing where a quartz crystal's shock sensitivity is a concern. ## Supply flexibility and standby control The standby (power-down) function pulls the disable current down to 15 µA max — useful for battery-backed modules that need to stop the clock during sleep and wake on an external event. Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm, with a seated height of 0.90 mm. Surface-mount assembly with standard reflow profiles; no special bake-out required for the MEMS die.","metaTitle":"DSC1001CI2-004.3000T Microchip MEMS XO, 4.3 MHz, CMOS","metaDescription":"Active Microchip DSC1001 MEMS oscillator, 4.3 MHz, CMOS output, ±25 ppm stability, 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":"DSC1001","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"4.3 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C ~ 85°C","Current - Supply (Max)":"6.3mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1001CI2-004.3000T AEC-Q100 qualified?","answer":"Yes — the ratings field lists AEC-Q100 qualification.

The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which can matter in automotive or industrial environments. Pinout and footprint match the standard 4-SMD no-lead oscillator layout, so it is a drop-in replacement on the BOM."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI2-004.3000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI2-004.3000T when reusing this data.
