So I bought a reel each of BF862-235 and BF862-215. Other parts seem to have the same suffixes, but a quick web search comes up with nothing useful, and the datasheet links for the two types of parts go straight to the same place. I'd guess this has something to do with ROHS/halogen free/greenie-knotted-knickers-of-the-month, but don't know for sure. Wisdom?

I don't see anything about what the 215 or 235 means, though.

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! Mikek

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!
