I got some Vishay transistors from RS supplies later last year for my Salas Reflektor D builds. I thought they looked cheap and nasty with a shiny almost chrome dipped look to them and messy part numbers.
Recently got some of the same from Mouser and they look different again. No horrible shiny coating on the metal, nice clear legible writing, different notches on the tab.
Just different batches? Both come from China apparently

Not always true, long production life parts like this have been migrated from fab to fab and had process changes. These are shrinks of the cell geometry, which allow the same Rds etc to be achieved with slightly smaller die, increasing profit per wafer.
The snag is that the linear operation SOAR specs have got worse over the years
no one ever wondered why plumb lines were called that. Heathens the lot of you

Best regards!
Can’t change process or geometry without issuing a PCN or use a new part code. At least that is what reputable companies do.
