The DSC6111CI2A-000.0000T: It is rated AEC-Q100, meaning it passed the automotive-grade stress tests for temperature, humidity, and reliability.
Supply voltage, power draw, and standby function
Maximum supply current is 3 mA when active, and only 10.5 µA when disabled via the Standby pin — useful for battery-powered designs that sleep most of the time. This is a hardware shutdown, not a software trick — the clock stops cleanly and restarts within a few milliseconds.
Package, footprint, and programming
The footprint is standard for 4-pin MEMS oscillators — pin 1 is Standby (or NC), pin 2 is GND, pin 3 is Output, pin 4 is VDD. This variant is a Blank (User Must Program) device — it ships without a pre-set frequency. You program the output frequency using Microchip's programming tool or a pre-programmed order code. For a fixed-frequency need, order a pre-programmed DSC61XX part instead.
Lifecycle reality and sourcing
No official successor is listed in the available records. If you need a pin-compatible alternative in the same DSC61XX family, a pre-programmed variant with the same package and supply range may work, but verify the Standby function and output type match your design.
