Product details

The DSC1030BE2-027.1200 is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 27.12 MHz CMOS output with ±25 ppm frequency stability across its -20 to 70°C operating range. At 3 mA max supply current and just 1 µA in standby (power-down mode), it suits always-on peripherals or battery-backed real-time clock references where every microamp counts.

Active lifecycle — no end-of-line risk

New designs and production replenishment are straightforward through independent distribution.

Package and footprint — 5.0×3.2 mm 4-SMD

Housed in a 5.00 mm × 3.20 mm 4-SMD no-lead package, seated height 0.90 mm max.

Frequently asked questions

Where can I find the datasheet for DSC1030BE2-027.1200?

The datasheet is published by Microchip Technology under the base product number DSC1030. It covers the full PureSilicon™ oscillator family, including the 27.12 MHz variant, with electrical characteristics, timing diagrams, and application notes.

What is the closest pin-compatible alternative to DSC1030BE2-027.1200 in this Crystals & Oscillators family?

Within the DSC1030 series, any oscillator sharing the same 4-SMD package and supply voltage (3V) is footprint-compatible. The key differentiator is frequency and stability — confirm the target frequency and ±25 ppm requirement before substituting.
