Product details

MEMS oscillator at 27.178 MHz with AEC-Q100 grade

The DSC6001CE1A-027.1780 is a MEMS-based XO (standard) from Microchip's DSC60XX series, delivering a fixed 27.178 MHz CMOS output with enable/disable function.

Microchip lists the DSC6001CE1A-027.1780 as obsolete. A board spin to a different oscillator is the only guaranteed long-term path.

Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint is standard for small-form-factor oscillators. The supply voltage range of 1.71V to 3.63V covers 1.8V, 2.5V, and 3.3V logic rails without an external level translator — a single BOM line serves multiple voltage domains.

Frequently asked questions

Is DSC6001CE1A-027.1780 obsolete?

Buyers need to know if the part is end-of-life to plan for redesign or find drop-in replacements.

What is the replacement for DSC6001CE1A-027.1780?

Sourcing buyers and maintenance techs must quickly identify an alternative that is in production and fits the design.

Where can I buy DSC6001CE1A-027.1780?

Even if obsolete, some buyers may still need to source existing inventory or leftover stock.

What is the datasheet for DSC6001CE1A-027.1780?

Design engineers need to verify electrical specs, pinout, and footprint before layout.

What is the pinout and package of DSC6001CE1A-027.1780?

Compatibility with PCB layout is critical; engineers require exact mechanical and electrical details.

What are alternatives to DSC6001CE1A-027.1780?

Because the part is obsolete, finding a direct or functional alternative is the top priority for procurement and repair.
