Obsolete — sourcing path for the BOM line
The DSC6011MI1A-000.0000T is listed as Obsolete by Microchip Technology. This means the manufacturer has discontinued production and no further factory orders are accepted. For a BOM already qualified to this exact ordering code, the supply path runs through independent distribution — available to quote against an RFQ from surplus and last-time-buy inventory channels.
MEMS resonator, CMOS output — what the ratings mean for fit
A MEMS-based XO (Standard) replaces a quartz crystal plus oscillator circuit in a single package.
Programmable blank — what the ordering code means
This is a Blank (User Must Program) variant — the device ships without a pre-set output frequency. The user programs the desired frequency within the 1 MHz to 80 MHz range using Microchip's programming infrastructure before assembly. For tighter (±25 ppm) or spread-spectrum requirements, look at other DSC60XX family codes.
