The AEC-Q100 qualification places it squarely in automotive-grade timing — suitable for engine bay, cabin, or chassis-domain ECUs where a quartz crystal might drift or fail under vibration. The standby (power-down) function drops supply current to 15 µA max when the enable pin is pulled low, letting the ECU gate the clock in sleep mode without a separate load switch. Active draw is 6.5 mA max at 1.8V–3.3V supply — low enough for a shared 3.3V rail on a mixed-signal board. ## Package, footprint, and the rework bench reality Housed in a 4-SMD, no-lead exposed-pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. Surface-mount rework with hot air is straightforward; the pad pitch is generous enough that a standard fine-tip iron can touch up a lifted pad. ## Lifecycle and sourcing for production and repair The DSC1004 series is a current Microchip catalog line, so new designs can commit to it without an imminent last-time-buy window. For a repair bench pulling a dead oscillator off an automotive controller board, this is the exact drop-in replacement; no pin-compatible second source is listed, but the MEMS construction means it's less prone to the mechanical shock failures that take out quartz cans.","metaTitle":"DSC1004AL1-001.0000T AEC-Q100 1 MHz MEMS Oscillator","metaDescription":"Active production 1 MHz XO, CMOS output, AEC-Q100 qualified, -40°C to 105°C, standby function with 15 µA disable current. 7.00mm x 5.00mm 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":"DSC1004","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"1 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":"DSC1004","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~105°C","Current - Supply (Max)":"6.5mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the standby current of the DSC1004AL1-001.0000T?","answer":"The disable (standby) supply current is 15 µA maximum.
