Product details

MEMS oscillator in a standard 4-pin SMD footprint

It fits the same 5.0 mm x 3.2 mm 4-SMD no-lead footprint as a quartz oscillator, so a board laid out for a quartz can is a direct swap — no layout change, no BOM re-spin.

For a battery-powered sensor that sleeps most of the time, that disable current is below the self-discharge of a CR2032 coin cell — the oscillator itself won't drain the battery between wake cycles.

Temperature grade and deployment range

It belongs in indoor equipment, office peripherals, and appliance PCBs — not in a motor drive cabinet or an outdoor telecom enclosure where the ambient can dip below -20°C or climb past 70°C.

Microchip lists the DSC1033BE1-008.0000T as Active. For a BOM that needs this frequency and package, the supply chain risk is low — no imminent EOL to plan around.

Frequently asked questions

Is the DSC1033BE1-008.0000T obsolete?

No — it carries an Active product status from Microchip.

What is the output of the DSC1033BE1-008.0000T?

CMOS — a single-ended square-wave output that drives standard logic inputs directly without external termination.

What is the difference between MEMS and quartz oscillators?

A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. The DSC1033BE1-008.0000T is a MEMS XO; it offers lower jitter and faster start-up than a typical quartz oscillator, and it is less sensitive to vibration and shock. The footprint and pinout are the same, so it is a drop-in replacement for a quartz XO in the same package.

Can I use a 3.3 V oscillator on a 5 V system?

No — the DSC1033BE1-008.0000T is specified for a 3.3 V supply. Driving it from 5 V exceeds the absolute maximum rating and will damage the device. If your system runs at 5 V, select a 5 V-rated oscillator in the same package.
