Re: si5351a-b-gt Vs si5351a-b-gtr

Bottom line, doesn't matter, all the same chip.


But it is curious:

Mouser says GT gets shipped in a tube,  GTR is a reel, or tape cut from a reel.
They'll sell you either one in single chip quantities.

Datasheet from SiLabs says GT is "coil tape", GTR is "tape and reel".
Not obvious to me what that distinction might be, but Gary could be right and GT is cut tape.
There are occasional errors in SiLabs docs for the Si535, especially AN619.

Pick and place machines can usually take a mix of tubes and reels.

No difference in the chip or package. 
suffix GTR just denotes tape and reel... for large quantities used in manufacturing / pick and place you most likely would want inventory on a reel.
GT is just the cut tape.... a small section of the same tape that would be on a reel.

GTR means comes off a reel, you get them as cut tape.
GT means they come in a tube.
