How to swap it in a recipe
Bitterness scales with alpha acid times weight, so for bittering additions rescale the weight by the alpha ratio — the multiplier for each substitute is given below. For late, whirlpool and dry-hop additions dose 1:1 by weight and go by aroma instead, because alpha acids do not drive those.

Look for similar alpha acid content (within 2%) and overlapping aroma notes. The more shared notes, the safer the swap.
