"metric" 48 pitch is NOT 48dp. This is a term that has been coined by Tamiya themselves but what they are referring to are their 0.6mm pitch gears, and, if you do the conversion, this is equivalent to 42.3333dp.
There will be no problem if you use pinions and spurs that match, so a Robinson Racing "metric" 48 pitch pinion will match a Tamiya 06 module spur and vice versa, but don't try running a mix of 48dp and "metric" 48 pitch because there will be tears before tea, as my granny used to say
