[Ronja] SFH 495 as alternate IR transmitter?

[Saad Shakeel]

Hey everyone,
   
  I'd like your opinion about the possibility of using a SFH 495 IR diode.
  http://pdf1.alldatasheet.com/datasheet-pdf/view/45680/SIEMENS/SFH495P.html
   
  It has a rise time of 7ns and a half angle of 30 degrees at 2.1 volts.
   
  Please let me know if this may be used as an alternate to HSDL-4230.
   
  Thanks
   
   
  Saad
   
   
  P.S.
   
  I found some shopkeepers here selling used 74hc133s... 
  Any idea from where they might have extracted those? And would they still be reliable to work with?
