     Good on you for figuring it out, I saw the quantity difference, but 
then ran across the current difference on Mouser.
I wasn't sure about it then, that's why I left it open
by saying, "I'll let you figure it out from there."
Glad someone did!

PS. Kinda poor practice by Mouser.

The transistor itself seems to be identical. 
The same spec sheet is referenced for both:
    http://www.mouser.com/ds/2/302/BF862-840156.pdf

For some reason, NXP's or Mouser's data-capture picked out 
two different Idss specs. (25mA, 40mA). Both are listed in 
the spec sheet, under two different test conditions. Never 
trust the online product selectors! ;-)

Ah, okay, reel size.  Thanks.

On the Mouser site, I see the Continuous drain current is different, the 
235 is 25ma the 215 is 40ma.  However look it over, the description 
column has 25ma for the 235 and 10ma for the 215.
   I'll let you figure it out from there.
Good luck!

ah, it appears to be reel diameter in mm.

Thanks, that's the page I bought them from.  I don't see anything about
what the 215 or 235 means, though.
