Hello Rick,
Unfortunately there is no direct replacement for the BF862 FET.
However, the BF861C would be a good replacement for this FET: https://www.nxp.com/docs/en/data-sheet/BF861A_BF861B_BF861C.pdf
It is very similar device also designed for preamplifiers for AM tuners in car radios, with very few differences like drain-source voltage and transfer admittance.
Best regards,
Tomas
Hello,
We have used the BF862 JFET in a sub-assembly. Is there an explanation as to why NXP discontinued this device? A very good JFET. Also, please recommend a "next best" replacement. Thank you!
Best regards,
