Product details

The DSC6003HI2A-027.0000 is officially obsolete per Microchip's product status. No successor part number is listed in the public record — any replacement will require a pin-compatible or functionally equivalent oscillator from the same or another family. For existing designs that cannot be respun, independent distribution channels may hold surplus stock.

A 27 MHz XO (Standard) built on a MEMS resonator rather than a quartz crystal, outputting CMOS levels across a 1.71V–3.63V supply range.

Compact 4-SMD no-lead footprint

Housed in a 1.60 mm x 1.20 mm 4-SMD no-lead package with a seated height of 0.89 mm.

Frequently asked questions

What is the replacement for DSC6003HI2A-027.0000?

Microchip has not published a direct successor part number. A functionally equivalent replacement would need to match the 27 MHz frequency, CMOS output, ±25 ppm stability, 1.71V–3.63V supply, and AEC-Q100 qualification in a 4-SMD no-lead package. The DSC60XX series includes other active variants; confirm pin-compatibility and specs against the BOM requirement.

Is DSC6003HI2A-027.0000 pin compatible with standard 4-SMD oscillators?

The 4-SMD no-lead package (1.60 mm x 1.20 mm) follows the common MEMS oscillator footprint. Most standard 4-pin oscillators of similar size use the same pad layout — verify the pin 1 function (Enable/Disable) against your board's oscillator socket before substituting.
