AEC-Q100 qualification means this part carries the automotive-grade documentation an OEM auditor expects — the PPAP package includes the temperature-grade reliability data, not just a datasheet footnote. The 1.8–3.3 V operating range covers the three most common digital supply voltages in a single BOM line — a 1.8 V MCU core and a 3.3 V Ethernet PHY on the same board use the same oscillator order code. ## Active lifecycle — no obsolescence watch for new designs Product status is Active — no last-time-buy deadline, no NRND flag.","metaTitle":"DSC1001BE1-040.0000 – Microchip MEMS XO, 40 MHz CMOS","metaDescription":"DSC1001BE1-040.0000 from Microchip Technology: 40 MHz MEMS-based XO, CMOS output, 1.8–3.3 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":"DSC1001","Package":"Tube","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"40 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1001BE1-040.0000/alternatives.json"},"ai":{"faq":[{"question":"Can DSC1001BE1-040.0000 replace a standard quartz oscillator of the same frequency and package?","answer":"Yes, in most cases. The DSC1001BE1-040.0000 is a MEMS-based XO in a standard 4-SMD, no-lead package (5.0 mm × 3.2 mm, 0.90 mm height) that is footprint-compatible with quartz oscillators of the same dimensions. The MEMS resonator is less sensitive to vibration and shock than a quartz crystal, which can be an advantage in automotive or industrial environments. The key differences: MEMS oscillators typically have a wider supply voltage range (1.8–3.3 V) and may draw slightly higher supply current (7.2 mA max) than a quartz equivalent at the same frequency.
