The PB180 (like all 68k PBs but the 150 and the 190) uses a SCSI rather than an IDE drive. Your 1400 uses IDE. That drive isn't going to work in your 180.
There are SCSI-IDE laptop adapters from the early 90s (in fact, Apple sold them in some PB540c and 550c models, with 750MB or so IDE drives fitted to an adapter), and there were aftermarket products sold for a time that did the same thing for PB owners wanting more strorage. Also, there is a new product available from a Japanese eBay seller specifically for CF storage in PowerBooks, but these are now either relatively rare, or else in the latter case price is a factor. But it can be done if you have the patience or the will.
I have, however, seen the OEM adapters sold on here once every couple of years or so, so you could try your luck — or else just buy a non-functional old scsi PowerBook and cannibalize it for the drive.
