A Synchro Substitute Monster is a monster with an effect that allows it to replace a single Synchro Material Monster that must have a specific name or be of a specific archetype for the Synchro Summon of a Synchro Monster. Unlike a Fusion Substitute Monster, the other Synchro Material Monster(s) do not have to be the correct one(s), but there isn't a situation where this would be applicable.

Treated as alternate name
Some cards can replace Synchro Material Monsters by treating their name as that of a Synchro Material Monster.
For example, "Pain Painter's" name is treated as "Plaguespreader Zombie" while it is face-up on the field. It can be used as the Tuner monster in the Synchro Summon of monsters such as "Archfiend Zombie Skull" that require specific Tuner monsters.
