Are these suitable for use on C64 breadbin motherboard?

NO, they are not! C64 mainboards 326298, 250407 and 250425 require 4164 DRAM type 64k x 1.

Boards 250466 and 250469 require 41464 DRAM type 64k x 4.

AFAIK, the only use for a C64 user for DRAM 41256 is if you have a 1750 REU 256k and want to boost it to 512k. You'll need 8 of these. Otherwise it's useless and I am surprised to find this in the Commodore section.
