The DSC1033AE1-005.0000T is a 5 MHz XO (Standard) clock oscillator from Microchip's PureSilicon™ MEMS family. The MEMS resonator eliminates the quartz-crystal startup and vibration sensitivity — the oscillator is ready at power-on and holds frequency under mechanical shock. Typical supply draw is 3 mA, dropping to 1 µA in standby (power-down) mode.
Package and board-fit details
Housed in a 7.00 mm × 5.00 mm 4-SMD no-lead exposed pad package, seated height 0.90 mm. Surface-mount reflow profile follows JEDEC J-STD-020; no special handling beyond standard MSL precautions.
No pin-compatible replacement or second-source is recorded for this exact order code. The DSC1033 series includes other frequencies and stability grades; confirm the BOM's frequency and tolerance before substituting.
