The footprint is compatible with standard quartz XO layouts of the same dimensions – a drop-in swap for a quartz part is possible if the supply voltage and output type match. No via-in-pad required; standard SMD reflow profile applies.","metaTitle":"DSC1030BC1-027.0000T MEMS XO, 27 MHz, CMOS","metaDescription":"Microchip DSC1030BC1-027.0000T MEMS oscillator, 27 MHz, CMOS output, 3V supply, ±50ppm stability, 4-SMD package.

We source it through independent surplus channels per your RFQ. Submit a quote request with your target quantity; we confirm availability and pricing at quote time. No stock-holding claim is made."},{"question":"Does the DSC1030BC1-027.0000T have a standby function?","answer":"Yes, the function is listed as Standby (Power Down).
