For an under-hood or cabin deployment, the temperature range is the limiting factor, not the qualification label. Supply voltage spans 1.71 V to 3.63 V, covering 1.8 V, 2.5 V, and 3.3 V rails without an external regulator. Typical current draw is 1.3 mA max, which keeps the thermal contribution negligible even in a dense PCB layout.
Obsolete — last-time-buy sourcing
Microchip lists the DSC6003ME2A-PROGRAMMABLE as Obsolete. For existing BOM lines, availability is through independent distribution on a quoted-to-order basis — no production stock is held. Confirm the required quantity and frequency range at RFQ. No official successor part is listed by Microchip for this specific order code. The DSC60XX series includes other programmable MEMS oscillators; a pin-compatible drop-in may exist with a different order code. Cross-reference the package (4-SMD, 2.0 x 1.6 mm) and supply voltage range when selecting a replacement.
Enable/disable function and package fit
When disabled, the oscillator stops switching, cutting the dynamic current to near-zero. The 4-SMD, No Lead package measures 2.0 mm x 1.6 mm with a seated height of 0.89 mm max. This is a standard 2.0 x 1.6 mm footprint (often called 2016), compatible with most pick-and-place lines. The surface-mount pads are on the bottom — no leads to bend or inspect.
