No need same brand. Just make sure that your plate/L-plate/L-bracket and the tripod head uses the same "mount", aka dove-tail aka Arca-Swiss style mount. Or which ever other mounting type there is in the market.
Acra Swiss style clamps and plates pretty much works interchangeably between brands. The only exception is the Lever Release Clamp from Really Right Stuff, it only takes on a certain size. But some brands' plates work ok with RRS, these include plates from RRS (of course), Markins, Krik, Camdapter, Kanrinpoche (only the L plates). Benro and Photo-Clam plates do not work well with RRS LR clamps.
