For a battery-powered sensor that sleeps most of the time, that disable current is below the self-discharge of a CR2032 coin cell — the oscillator itself won't drain the battery between wake cycles. ## Temperature grade and deployment range It belongs in indoor equipment, office peripherals, and appliance PCBs — not in a motor drive cabinet or an outdoor telecom enclosure where the ambient can dip below -20°C or climb past 70°C. Microchip lists the DSC1033BE1-008.0000T as Active. For a BOM that needs this frequency and package, the supply chain risk is low — no imminent EOL to plan around.","metaTitle":"DSC1033BE1-008.0000T MEMS XO 8 MHz CMOS 3.3V Active","metaDescription":"Microchip DSC1033BE1-008.0000T MEMS oscillator, 8 MHz, CMOS output, 3.3V, ±50 ppm, -20°C to 70°C, 4-SMD no-lead.

The DSC1033BE1-008.0000T is a MEMS XO; it offers lower jitter and faster start-up than a typical quartz oscillator, and it is less sensitive to vibration and shock. The footprint and pinout are the same, so it is a drop-in replacement for a quartz XO in the same package."},{"question":"Can I use a 3.3 V oscillator on a 5 V system?","answer":"No — the DSC1033BE1-008.0000T is specified for a 3.3 V supply. Driving it from 5 V exceeds the absolute maximum rating and will damage the device. If your system runs at 5 V, select a 5 V-rated oscillator in the same package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033BE1-008.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033BE1-008.0000T when reusing this data.
