Procurement Notes

Verify the obsolete status and end-of-life notifications directly with NXP Semiconductors before procurement planning. Confirm that the SOT-23 package dimensions match your PCB footprint requirements. Ensure compatibility with 100MHz operational frequencies for your specific design. Check for alternative components if long-term supply stability is required.

Selection Notes

Select this component when an N-Channel JFET is required for 100MHz RF applications. Consider the 20V voltage rating and 30mA current limits for biasing conditions. Evaluate the 1.5dB noise figure against system sensitivity requirements. Verify the SOT-23 package availability for assembly processes.

Part Context

The BF511,215 belongs to NXP's RF FET transistor series. It is specifically engineered for high-frequency analog applications. The part utilizes standard semiconductor manufacturing processes for JFETs. It serves as a discrete active component in RF systems.

Replacement Considerations

Public sources indicate this part is No Longer Manufactured or Obsolete. Consult NXP official documentation for confirmed substitute part numbers. Do not assume generic RF JFETs are direct replacements without verifying pinout and electrical specifications.
