24 MHz MEMS oscillator — what it replaces and where it fits
The DSC1033BE2-024.0000 is a MEMS-based oscillator from Microchip's PureSilicon™ series, delivering a 24 MHz CMOS clock from a 3.3 V supply rail. Its 4-SMD, No Lead package (5.00 mm x 3.20 mm footprint) matches the industry-standard 5.0 x 3.2 mm quartz oscillator land pattern — a direct drop-in for boards originally laid out for a quartz XO.
No official successor part number is listed in the product documentation; the MEMS oscillator family has moved to newer series with different ordering codes. For existing designs that require this exact order code, stock is available through independent surplus channels. The 4-SMD, No Lead package and 3.3 V supply are common across many 24 MHz oscillators, so a board-level replacement is feasible if a pin-compatible alternative is identified. No direct Microchip cross-reference is published.
