You can get replacement key in 1.5, 1 size in DCS profile from Signature Plastics with or without legend. Or if legend is OK, then also from Cherry keyboards. Just keep in mind that neither of those will have the same key shape and height as the stock keycap on the Razer, so it would be best to get an entire set for uniform typing feeling. Of course may be one of those people that mismatch does not bother. In that case if not matching profile is no concern, you could simply get key from wrong row and use tab and letter key from that row if buy from wasd.
