MEMS XO with AEC-Q100 — what the ratings mean for the BOM
The DSC6102MI1A-000.0000T: That makes it suitable for under-hood or chassis-mounted electronics where the ambient sees -40°C to +85°C and vibration is constant. For a CAN bus or FlexRay clock running at 40 MHz, ±50 ppm keeps the bit timing within the 1% tolerance window without external trimming.
Lifecycle reality and sourcing posture
Microchip lists the DSC6102MI1A-000.0000T as Obsolete. No official successor order code is recorded in the lifecycle data — the DSC61XX family has been superseded by newer MEMS oscillator families from Microchip, but a direct pin-compatible drop-in is not confirmed on this record. Sourced through independent distribution channels against an RFQ. For volume BOM requirements or last-time-buy inquiries, submit an RFQ with the target quantity and date-code window.
