Stripboard with 2.0mm spacing
2.0mm proto boards exist, but they are rare and EXPENSIVE. They're also oversized if you only have one 2.00mm pitch component. Vectorboard makes them (all their stuff is overpriced) and Digikey and Mouser carry their products.

A better solution is Proto-Advantage's so-called "pitch changer" PCBs. They have their own online store, but Digikey also carries their products:

EDIT: Seems Proto-Advantage only carries single row pitch changers and if you have two rows that are 2.00mm apart, then you probably don't have enough space to use two back-to-back pitch changers.
