Frequency stability is ±25 ppm across the full supply range of 1.8 V to 3.3 V — tight enough for a general-purpose clock in an automotive body controller or infotainment head unit, but not for precision Ethernet or USB timing where ±50 ppm or better is typical. ## Standby power-down and supply current — the battery-aware edge Active supply current is 7.2 mA max, typical for a 27 MHz CMOS-output oscillator at 3.3 V. The 4-SMD no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm max. The land pattern is standard for this footprint class — no via-in-pad required, but the small pads need a well-controlled solder paste stencil to avoid bridging. No through-hole variant exists in this series. No stock-holding claim; each order is placed to the supply chain.","metaTitle":"DSC1001DC2-027.0000T MEMS XO – 27MHz, AEC-Q100, 2.5x2.0mm","metaDescription":"Microchip DSC1001DC2-027.0000T: 27MHz MEMS oscillator, CMOS output, AEC-Q100 rated, ±25ppm stability, 1.8-3.3V supply, 4-SMD 2.5x2.0mm.","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":"27 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"0°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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How do I order DSC1001DC2-027.0000T and check availability?","answer":"This is an active-production part.

No on-hand stock is claimed — every order is placed to the supply chain."},{"question":"Can DSC1001DC2-027.0000T replace a standard 27 MHz quartz oscillator?","answer":"Yes, if the original oscillator is a 27 MHz CMOS-output XO in a similar 4-SMD footprint. The MEMS-based DSC1001 is a drop-in replacement for many quartz XOs — same supply range (1.8 V to 3.3 V), same output type, same ±25 ppm stability. Confirm the original part's package dimensions (2.50 mm x 2.00 mm) and pinout match before committing the BOM."},{"question":"What is the standby power-down current for DSC1001DC2-027.0000T?","answer":"Maximum 15 µA when the Standby (Power Down) function is active. This is the current draw from the supply rail when the output is disabled — low enough for battery-powered wake-up circuits or RTC backup."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DC2-027.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DC2-027.0000T when reusing this data.
