Product details

MEMS oscillator replaces quartz at 32.768 MHz

It runs from a 3.3V supply and draws 3 mA typical during operation, dropping to 1 µA max in standby mode via the Power Down pin — a meaningful power savings for battery-powered or intermittently active systems.

Package and board-fit for hand assembly

Housed in a 4-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the footprint is a standard 4-pad land pattern that reflows easily with a hot-air station — no BGA rework required. The 0.197" × 0.126" body is a common size for oscillators, so existing PCB layouts for quartz oscillators in the same footprint often accept this MEMS part with no board spin.

Frequently asked questions

Can I use DSC1033BI2-032.7680 as a replacement for a quartz oscillator?

Yes, the DSC1033BI2-032.7680 is a MEMS-based oscillator that is pin-compatible with many standard 4-pad quartz oscillators in the same 5.0×3.2 mm footprint. The CMOS output and 3.3V supply match common quartz oscillator specs, and the ±25 ppm stability is comparable to a basic quartz XO. The MEMS resonator is more shock- and vibration-tolerant than quartz, which can be an advantage in industrial or portable gear.

What is the closest pin-compatible alternative to DSC1033BI2-032.7680?

Within the DSC1033 family, other frequency variants in the same 4-SMD package and 3.3V supply are pin-compatible — only the frequency changes. For a direct replacement at 32.768 MHz, the DSC1033BI2-032.7680 is the specific order code. No official second-source part is listed by Microchip, but any standard 32.768 MHz CMOS XO in a 5.0×3.2 mm 4-pad package with 3.3V supply and ±25 ppm stability is a functional equivalent — confirm the standby pin function matches your schematic.
