The flybe connections timetable clearly shows the 175 on both flights and amadeus also should be correct. I would say at present the intention is for
the flight to be operated by the 175.
If you have noted the Q400 from the booking engine, I would not necessary trust that.
However with so long between now and the departure date things could change but the connections timetable seems to be fairly accurate other than of course last minute aircraft substitutions.
