Housed in a 5.00 mm × 3.20 mm 4-SMD, No Lead package with a seated height of 0.90 mm. The no-lead construction reduces parasitic inductance compared to a gull-wing lead — cleaner clock edges into the load capacitance. The 0.197\" × 0.126\" footprint is common across the DSC1001 series, so a layout swap between frequency variants is a BOM change, not a board spin.","metaTitle":"DSC1001BI2-026.9730 MEMS XO – 26.973 MHz, AEC-Q100, ±25 ppm","metaDescription":"Microchip DSC1001BI2-026.9730: MEMS XO, 26.973 MHz CMOS, ±25 ppm stability, -40°C to 85°C, AEC-Q100.

The Standby (Power Down) function disables the output and reduces supply current to 15 µA max. The oscillator resumes normal operation when the standby pin is de-asserted; no external load switch or enable circuit is needed."},{"question":"Is DSC1001BI2-026.9730 AEC-Q100 qualified?","answer":"Yes, it carries an AEC-Q100 rating. This qualifies the part for automotive applications requiring PPAP and reliability stress testing per the AEC-Q100 standard — under-hood, cabin, or chassis domains."},{"question":"Is DSC1001BI2-026.9730 compatible with a 2.5V supply?","answer":"Yes. 2.5V falls within the 1.8V to 3.3V supply range. No external level shifting or regulation is required."},{"question":"What is the closest pin-compatible alternative in the DSC1001 family?","answer":"The DSC1001 series shares the same 4-SMD package, pinout, and supply range across all frequency variants. To change frequency, replace the order code suffix while keeping the same PCB footprint — no board layout change is required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BI2-026.9730","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BI2-026.9730 when reusing this data.
