Lifecycle reality for this 25 MHz MEMS XO
The DSC6101CI2A-025.0000T: No official successor order code is recorded. If a pin-compatible drop-in is needed, a board-level qualification of a current-series MEMS XO from the same DSC61XX family will be required.
Sourcing this obsolete order code
Because the DSC6101CI2A-025.0000T is obsolete, new stock is not flowing through Microchip's standard distribution. We source it through independent surplus channels — each lot is verified for authenticity and the quantity is confirmed at RFQ. For a BOM that needs a drop-in replacement, a current-production MEMS XO from the same DSC61XX family with matching 25 MHz, CMOS output, and ±25 ppm stability is the logical cross-reference candidate — confirm the supply voltage range and enable/disable pinout before committing.
