Product details

The DSC6003CI2A-027.7100 is a MEMS-based XO (Standard) oscillator from Microchip's DSC60XX series, delivering a 27.71 MHz CMOS output with ±25 ppm frequency stability across the full -40°C to +85°C industrial temperature range.

Wide Supply Range and Low Power in a Compact 4-VDFN

Operating from 1.71V to 3.63V, it covers 1.8V, 2.5V, and 3.3V logic rails without a separate level translator. The 4-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts.

The DSC6003CI2A-027.7100 is officially obsolete per Microchip's product status. This is a last-time-buy or surplus sourcing scenario, not a production-run part.

Frequently asked questions

How can I order the DSC6003CI2A-027.7100 or check availability?

This part is obsolete, so it is not stocked for immediate shipment. We source it through independent distribution channels — submit an RFQ with your target quantity, and we will confirm availability and pricing at quote time. No minimum order commitment is required for a quote.

What is the replacement for the DSC6003CI2A-027.7100?

The evidence does not list a specific successor order code. For a functionally equivalent MEMS oscillator at 27.71 MHz with CMOS output and AEC-Q100 rating, review Microchip's active DSC60XX series parts. A board-level cross-reference may require verifying the package footprint and supply voltage range.
