The DSC6101CI2A-008.0000T: If you need a drop-in replacement, the closest functional match would be another DSC61XX-series part with the same 8 MHz frequency, CMOS output, and 4-VDFN footprint — but pin compatibility and electrical ratings must be verified against the original BOM position before committing.
Frequency stability is held to ±25 ppm, tight enough for a CAN bus or a basic MCU clock tree where the system can tolerate a few ppm of drift over temperature.
Because the DSC6101CI2A-008.0000T is obsolete, it is not available through Microchip's standard distribution. We source it through independent surplus channels — each lot is verified for authenticity and date code, and availability is confirmed at the time of your RFQ. If you are designing a new board, do not spec this part — choose an active DSC61XX variant or a different MEMS oscillator with the same 8 MHz, CMOS, 4-VDFN parameters. For an existing production line that already uses this order code, we can help locate inventory while it lasts.
