Card Reader Not Working Will In Internal Card Reader With Nine Pins Work In The Place Of A Floppy Drive?

Will in internal card reader with nine pins work in the place of a floppy drive? - card reader not working

I have the disc and went to Maplin card but internal power cable had a keel. I shot this device had a power cord to the nines. Coming home, I opened the box and found a new replacement of pines on the motherboard. If the new internal card reader working, if I connect to the nine pin on the motherboard?
FNAC has a right of return, so I do not buy?
