2SK3557-6-TB-E is a possible replacement. One could try 2SK209 as well. Since I had a enough BF862 to build mine, I did not try 2SK3557-6-TB-E, even though I bought enough of them to use but did not perform a second build.
This is the Mouser shopping cart I put together for my build

Fits on sot-23, 16 pcs. in par. got me 0.35 nV/rt Hz at Id = 47 mA total.
NSVJ3910 is the same, IIRC even same marking. You cannot tell them apart
when taken out of the tape.
There are also JFE140 by TI, not pin compatible, but with protection diodes.
There is a thread on them started by TI FAEs in the sellers section.
Performance-wise in the same class. I have a few, but not tested.
