AI Summary

SiT8008AI-12-18S-27.00000D by SiTime: LVCMOS HCMOS Programmable Oscillator 27MHz 1.8V SMD2520-4P.

DSC1001DI2-027.0000 is a MEMS clock oscillator from Microchip in a 2.5 mm x 2.0 mm 4-VDFN footprint. It matches the target part's 27 MHz frequency, 1.8V supply, ±25 ppm stability, industrial temperature range, and Pin 1 Standby function.

  • Low-power MEMS clock oscillator second-source alternative
  • Pin-compatible 2.5 x 2.0 mm footprint and 1.8V supply voltage

SiT8008BI-11-18S-27.000000D is a higher-accuracy sibling variant from the SiT8008 family. It provides ±20 ppm frequency stability instead of ±25 ppm while maintaining complete pinout, package, and electrical drop-in compatibility.

  • Tighter frequency stability option (±20 ppm vs ±25 ppm target) for higher clock accuracy
  • Identical physical package, pinout, and 1.8V operating voltage

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
