Yes. Section 508 applies when Federal agencies "develop, procure, maintain, or use information and communication technology." Even if the agency is simply procuring a new version of an existing product, Section 508 applies. Section 508 requirements must be considered in the Brand Name justification and in the "or Equal" decision. It is a best practice to include Section 508 requirements in solicitation documentation for Brand Name or Equal, otherwise how are vendors able to propose products or services that equals the brand name?
