The DSC6101MI2A-027.0000T: For a BOM that already qualifies this oscillator, the AEC-Q100 grade and MEMS construction mean no reliability downgrade from the original qualification — the risk is solely supply continuity. A last-time-buy or bridge-buy evaluation at RFQ is the standard procurement path.
No official pin-compatible successor or cross-reference is listed by Microchip. The DSC61XX series contains other 27 MHz MEMS XO variants with the same 4-SMD package and supply range, but each has its own lifecycle status. A parametric search for 27 MHz, 1.8-3.3 V, ±25 ppm, AEC-Q100 in the same footprint is the best starting point for a replacement candidate.
