Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official documentation to confirm if it denotes a distinct variant or packaging configuration compared to standard LFXTAL023950 listings. Ensure compatibility with the target PCB footprint and reflow soldering profiles. Confirm current availability status through authorized distributors as supply chain conditions may vary.

Selection Notes

Select this component when a 16 MHz fundamental frequency with ±30 ppm stability is required in a compact SMD form factor. Consider the 70 Ohm ESR value for oscillator circuit design to ensure reliable startup. Evaluate the -40°C to +85°C range against environmental requirements. Compare against other CFPX-180 series parts for alternative frequencies or tolerances.
