One base designation across loaded brands
Exact designations rank first. Dimensions, suffixes and other technical differences remain visible so the result is not mistaken for an interchangeability declaration.
“UCF203” across 2 loaded brands
The base designation is shared, but too few brands have complete boundary dimensions. Use Custom Compare when you want to choose exact suffix variants yourself.
