$bStringToFind = StringTrimLeft(Binary($sStringToFind), 2)

;$aa = BinaryToString("0x" & $bStringToFind )

$hFile = FileOpen($sBinaryFile, 17)

So why do you need to convert to binary in order to replace "C"?

just want to replace "C" = F

Yeah, so why the binary read? anyway, you're on the right way, just close the opened file, re-open it in write mode and write the data after replacement into it.
