I have been trying to obtain two Roco 10735 DCC decoders, the ones with the 90 degree pins, to fit into my Roco Hf110c and Mh6 locos.
Having had a great deal of difficulty in obtaining them, they appear to be out of production, I thought that the Bachmann 36-556RA E-Z Command 90 Degrees 6 Pin DCC Decoder would do for now. It was larger that the Roco decoder but fitted nicely into the locos.
Having bought the Bachmann decoders I then find out that Roco reversed the pinouts on their locos so that only their decoders face the right way to allow the cab or tender bodies to fit! Either that or Bachmann are the culprits!
As Roco do not mark the number 1 pin on their loco sockets or chips you find this out the hard way when you cannot program the chip and the loco does not respond. It was only by using my ESU DCC decoder tester that I was able to verify this by comparison with a Roco chip without burning out the Bachmann chips.
It may be possible for my wife, who used to be an electronics technician, to remove the connector from the Bachmann units and resolder it onto the other side of the board to make it fit. This is not something I would try myself as my eyesight is just too poor to attempt it!
If anyone knows of a supplier of the Roco 10735 90 degree decoder I would very much appreciate a nod in their direction.
They are no longer listed on the Roco Europe web site so as you say they are not available at the moment. (They only list the straight pin version for H0e and I think this may be for the electric loco?)

However I think that Roco USA still list them as in stock:

I was informed on another forum that the original Roco decoder used was made by Kuehn, and you can still order it at http://www.kuehn-digital.de/lokdecoder01.html. It's the one with article no 81340 and at ~30
Interesting... I bought one from Gaugemaster earlier this year! Around April I think. They are the Roco/Fleischmann importers these days..
I also noticed that they are the other way around from the Bachmann chips, but I managed to check first before buying. I had already worked out which was pin 1 on the Roco decoders as one of my Mh's uses a six pin chip with wires and plug... Much cheaper! The other has a proper Roco chip, but that was before I had worked it out..
I should say that I did get the Kuehn chip and it fits and works exactly the same as the Roco chip.
This is probably a little late in the day But for info I have digitised several ROCO 0-6-0 Feldbahn & 0-8-0+TT Engarths
I simply take a standard 6 pin decoder and carefully bend the pins by holding them securely with a pair of long nosed small pliers and applying gentle pressure to the decoder to obtain a not quite 90' bend in the pins I have never actually measured the actual angle obtained it is probably about 100', this allows the decoder to fit the socket and the cab or tender body to be refitted.
I was naturally a little concerned at first when doing this, but everyone I have done continues to function fine.
