This is a genuine Mitsubishi RD16HHF1 transistor, obtained recently from Mitsubishi appointed distributor in United Kingdom.

SDR-Kits does not sell fake transistors. We have supplied thousands of genuine transistors since we first started the business in 2008.

Please note that due to a change of die-factory in Japan in 2017/2018, Mitsubishi changed the partnumber from RD16HHF1-101 (which shows the Mitsubishi Logo) to RD16HHF1-501 (which is shown in the product photo and no longer shows the Logo).   

Both RD16HHF16-501 and RD16HHF101 have identical performance!    

Any RD16HHF1-101 showing the Mitsubishi Logo is either OLD Stock or  a Fake    
you can check this by checking with some of the big Mitsubishi big authorized distributors (ie  rfparts in US or Anglia in the UK)
