No stock-holding claim is made here; every order is confirmed at quote time."},{"question":"Can the DSC1121CI2-066.6667T replace a standard quartz oscillator?","answer":"Yes, in most cases. The DSC1121CI2-066.6667T is a MEMS XO with CMOS output and a standard 6-SMD no-lead footprint (3.20 mm × 2.50 mm). It is a drop-in replacement for many quartz oscillators of the same size and pinout — but verify the pad layout and supply voltage (2.25 V – 3.6 V) against your existing quartz part.
