Product details

Sourcing this obsolete part

The DSC6331HI1BA-027.0000T: Availability is limited to surplus and independent-distribution channels. Quantities are lot-specific; pricing and lead time are confirmed at RFQ. The part is sourced to order against the BOM line.

Key specs for BOM-fit verification

Supply current is 3 mA typical, making this oscillator suitable for battery-powered or power-budgeted designs where every milliamp counts. The spread-spectrum feature (±0.50%, center spread) reduces peak EMI emissions at the fundamental frequency — useful when the 27 MHz clock radiates into nearby analog or RF sections.

Frequently asked questions

What is the closest alternative to the DSC6331HI1BA-027.0000T?

No pin-compatible or functional successor is specified by Microchip for this exact order code. A replacement would require selecting a different MEMS or quartz oscillator with the same 27 MHz frequency, LVCMOS output, 1.8V-3.3V supply, and 4-SMD footprint — a BOM change and board validation would be needed.
