Product details

MEMS oscillator at 4.75 MHz – active production

The DSC1033DC1-004.7500T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a fixed 4.75 MHz CMOS output at 3.3V supply with ±50 ppm frequency stability.

3 mA typical draw, 1 µA standby

The standby pin (function Standby) lets a system-level GPIO or power-management IC gate the clock; useful for IoT endpoints or metering hardware that cycles between active and deep-sleep states.

Commercial temp, SMD 2.5x2.0 mm

Housed in a 4-SMD no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm max; the small footprint suits space-constrained PCB layouts, but the no-lead terminations require careful solder-paste stencil design for reliable reflow.

Frequently asked questions

What is the standby power consumption of the DSC1033DC1-004.7500T?

When the standby (power-down) function is asserted, the maximum supply current drops to 1 µA. The oscillator stops and the output enters a high-impedance state.

Does the DSC1033DC1-004.7500T have an enable/disable function?

Yes, the part includes a Standby (Power Down) function. Asserting the standby pin disables the output and reduces current to 1 µA max.

What is the closest pin-compatible alternative to the DSC1033DC1-004.7500T in the DSC1033 family?

Any DSC1033 variant with the same 4-SMD no-lead package, 3.3V supply, and CMOS output is footprint-compatible — the difference is frequency and stability grade. For a direct drop-in at a different frequency, check the DSC1033 series ordering guide; no single pin-compatible alternative is listed for this exact 4.75 MHz part.
