Does the material component of Booming blade need to the same one used in the attack?

Does the spell specify that the material component need be the same as the one used in the attack?

As part of recent errata to the green-flame blade and booming blade cantrips, their material components have been amended to "a melee weapon worth at least 1 sp" (Sword Coast Adventurer’s Guide, 142).

If not then can you use a separate sword for the component?
