I have Pfaff, Brother, Singer, and Babylock machines. None of them seem to care what brand needle I use. I buy mostly schmetz because they are readily available locally. LyndaOH mentioned her mother's White threading differently. So does my antique Singer, but it's only because the needle is inserted differently. My DDIL was having a problem with needles in her new Singer, but it was because she was inserting the needle wrong. Be sure you follow your machine's instructions for which direction the flat side of the needle goes on.
