The DSC6121CI2A-00EU: Maximum current draw is 3 mA (typical), which keeps the thermal contribution negligible in a dense layout — no derating for adjacent components. CMOS output swings rail-to-rail, so it drives standard logic inputs without level translation at the load end.
No pin-compatible drop-in replacement is documented — a board spin may be required for a substitute.
The DSC6121CI2A-00EU is obsolete but available through independent surplus distribution.
No pin-compatible successor is listed by Microchip. A functionally equivalent MEMS XO with dual CMOS outputs in a 4-VDFN package may exist in the DSC61XX family, but pinout and electrical compatibility must be verified against the target PCB footprint.
