Pulsecoder αiAR128.

Gents, does anybody know the difference between the following pulsecoders - A860-2010-T341 and A860-2060-T321? Are they the same but only the difference in ordering no? Both are αiAR128. Can I use them interchangeably?

Look at the attached photos.

Thanks a lot for help.

I've just solved it - it's compatible and could be used interchangeably - I've just tested it
