The MEMS resonator replaces a quartz crystal, eliminating the need for external load capacitors and reducing board area to a 3.20 mm x 2.50 mm 4-SMD no-lead footprint.
Microchip lists the DSC1033CI1-001.0000 as Obsolete. A board spin to a different oscillator family or a quartz-based XO in the same 3.2 mm x 2.5 mm footprint may be necessary for new designs.
No official pin-compatible replacement is recorded from Microchip. For a 1 MHz MEMS oscillator in a 3.2 mm x 2.5 mm 4-SMD package, consider the active DSC1001 or DSC1121 series from Microchip, which offer similar frequency and temperature grades but require a board-level footprint and supply voltage check. Confirm the pinout and enable logic before substituting.
