Supply flexibility and standby power discipline
The part operates from a single 1.8V to 3.3V supply — one line item covers both a 1.8V MCU clock and a 3.3V FPGA reference without a separate regulator. For a battery-backed RTC or a sleep-mode sensor node, that disable current is low enough to leave the oscillator powered continuously without draining the coin cell.
Housed in a 4-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the DSC1001BI2-010.0000 is a standard footprint that matches many quartz oscillator pads — a direct drop-in replacement for existing 5×3.2 mm designs. The surface-mount package is supplied in tube; no special reflow profile beyond standard lead-free solder is required.
Microchip lists the DSC1001BI2-010.0000 as Active. No direct pin-compatible replacement or second source is cited, but the DSC1001 family is broad — if a different frequency or stability grade is needed later, the base product number DSC1001 covers the same package and supply range.
