The 0.197\" × 0.126\" body is a common size for oscillators, so existing PCB layouts for quartz oscillators in the same footprint often accept this MEMS part with no board spin.","metaTitle":"DSC1033BI2-032.7680 MEMS Oscillator 32.768 MHz CMOS ±25ppm","metaDescription":"Microchip DSC1033BI2-032.7680 XO (Standard) MEMS oscillator, 32.768 MHz CMOS output, ±25 ppm stability, -40°C to 85°C, 3.3V, 4-SMD.

The CMOS output and 3.3V supply match common quartz oscillator specs, and the ±25 ppm stability is comparable to a basic quartz XO. The MEMS resonator is more shock- and vibration-tolerant than quartz, which can be an advantage in industrial or portable gear."},{"question":"What is the closest pin-compatible alternative to DSC1033BI2-032.7680?","answer":"Within the DSC1033 family, other frequency variants in the same 4-SMD package and 3.3V supply are pin-compatible — only the frequency changes. For a direct replacement at 32.768 MHz, the DSC1033BI2-032.7680 is the specific order code. No official second-source part is listed by Microchip, but any standard 32.768 MHz CMOS XO in a 5.0×3.2 mm 4-pad package with 3.3V supply and ±25 ppm stability is a functional equivalent — confirm the standby pin function matches your schematic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033BI2-032.7680","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033BI2-032.7680 when reusing this data.
