Microchip DSC1033AI1-005.0000 is a 5 MHz MEMS-based XO (Standard) with CMOS output, in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm.
The 4-SMD package has no exposed pad, so rework is straightforward: hot air at 260°C peak, preheat the board to 150°C, and lift the part without lifting the pad.
The datasheet is available from Microchip under the base product number DSC1033. It covers the full family specifications, including frequency stability, supply current, and standby timing.
Both are MEMS oscillators from Microchip's PureSilicon series, but the DSC1033 includes a standby (power-down) function that the DSC1001 lacks. For a 5 MHz part, the DSC1033 draws 3 mA typical in active mode versus the DSC1001's similar draw, but the DSC1033 drops to 1 µA in standby – a key advantage for battery-powered designs. The DSC1001 offers a wider frequency stability option (±10 ppm) not available on the DSC1033.
The part is listed under Microchip's DSC1033 series, which is RoHS-compliant per standard Microchip declarations. The 4-SMD package is lead-free compatible.
