Supplied in Tube — not tape-and-reel, so if your pick-and-place line expects reel feed, factor in a tube-to-reel transfer or hand-place for prototype runs. ## Lifecycle reality — obsolete, sourced to order No official successor order code is listed on the lifecycle record, meaning there is no drop-in replacement from Microchip with the same dual-frequency output in the same package. If you need this exact frequency pair and footprint, the surplus route is the only option; a board spin to a different oscillator is the alternative.","metaTitle":"Microchip DSC6121JI2A-0090 MEMS XO, 6.1298MHz & 6.1679MHz","metaDescription":"Microchip DSC6121JI2A-0090 MEMS XO, 6.1298MHz & 6.1679MHz dual CMOS output, 1.71-3.63V, ±25ppm, -40°C~85°C, 4-VLGA.
