search term fritzing part w5500
Gets two hits (both appear to have problems though, although they would be easy for me to fix.) Let me know which if either matches what you have and if you want a fix.
search term fritzing part MCP23S17
hit 1 indicates it is available in the adafruit fritzing library on github (which isn’t loaded by default in Fritzing but can be downloaded and installed easily or just unzipped and the individual part loaded).
edit: I see there is also a user created part that I fixed up earlier (although I’d probably use the adafruit one myself ) that is available by searching the forums for MCP23017 (as that is an alternate part number for the same device). Checking the data sheet for alternate part numbers is also a good bet, although google was smart enough to search for both terms.
