Output is CMOS, compatible with most digital clock inputs. Supply current is 4 mA typ, dropping to 1 µA max when the Standby (Power Down) function is asserted. ## Industrial temperature and 2.5×2.0 mm footprint The 4-SMD no-lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a compact footprint for space-constrained PCBs. Frequency stability is ±50 ppm across the temperature range.","metaTitle":"DSC1030DI1-042.5000 MEMS Oscillator 42.5 MHz CMOS XO","metaDescription":"DSC1030DI1-042.5000 from Microchip Technology: 42.5 MHz XO (Standard) MEMS oscillator, CMOS output, 4 mA typ, 1 µA standby, -40°C~85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1030, PureSilicon™","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"42.5 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"4mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4b72b94fabfa3cb5855b7b290e3a940f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1030DI1-042.5000/alternatives.json"},"ai":{"faq":[{"question":"What is a direct replacement for DSC1030DI1-042.5000?","answer":"No official successor or pin-compatible replacement is listed by Microchip for this exact order code. The DSC1030 series includes other frequencies and options, but a functional replacement requires verifying the target frequency, supply voltage (3V), package (4-SMD no-lead), and standby function. Contact us with your BOM requirements for a cross-reference search."},{"question":"Does DSC1030DI1-042.5000 have a standby function?","answer":"Yes, the function is listed as Standby (Power Down). When the standby pin is asserted, the oscillator output is disabled and supply current drops to 1 µA max, allowing the clock to be gated off in low-power system states."},{"question":"How can I order DSC1030DI1-042.5000 or check availability?","answer":"Submit an RFQ with your target quantity and target date — we confirm availability and pricing through independent surplus sourcing channels at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1030DI1-042.5000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1030DI1-042.5000 when reusing this data.
