What this MEMS oscillator is and where it was used
The DSC6001MI1A-050.0000 is a MEMS-based XO (Standard) oscillator from Microchip's DSC60XX series, delivering a 50 MHz CMOS output in a 4-SMD, no-lead package measuring 2.00 mm x 1.60 mm. It operates across a wide supply range of 1.71 V to 3.63 V and draws a typical 1.3 mA, making it suitable for low-power automotive and industrial applications that require a compact, surface-mount clock source. The AEC-Q100 rating confirms it was qualified for automotive-grade reliability, typically under-hood or cabin environments where temperature swings and vibration are expected.
Obsolete – sourcing through surplus channels
Availability is limited to surplus and overstock lots; quantities are confirmed at RFQ and vary by lot.
Pin-compatible alternatives and replacement options
No direct pin-compatible replacement is listed by Microchip for this exact order code. Buyers needing a 50 MHz MEMS oscillator in the same 4-SMD footprint should evaluate other DSC60XX variants with matching supply voltage and stability specs, or consider a different series entirely — a board spin may be required.
