If a spell’s material components are consumed, can a spellcasting focus still be used in place of the consumed component?

@jackAbrasionIf a spell’s material components are consumed, can a spellcasting focus still be used in place of the consumed component? A spellcasting focus can't substitute for a component that is consumed.

@ZejetyDoes this ruling also apply to component pouches? Yes. See the Player's Handbook, p. 203. @jackAbrasion
