No, no, they were completely different physically: the 5300 had a ~12x4cm card whereas the 1400 took a fairly square ~6x4cm card.
Of course, they were the same electrically, more or less, and the connector may or may not be the same. It's a shame they weren't interchangeable, really, but besides the power plug, virtually nothing on the 1400 was the same as any other machine.
I was comparing by what was commonly installed: either video or nothing depending on a 5300's trim level (base and cs were often blank, c and ce almost always had video-out), or whatever was BTO in the 1400, which was often nothing - I've yet to see a 1400 with a factory-installed card.
There were 3rd party manufacturers that provided other capabilities, such as my Focus 16vEN Ethernet/video card combo for the 5300, and whatever model Ethernet card (I think it's Focus) is in my 1400.
