P-Mount, T4P

P-mount cartridges (T4P) are designed to be interchangeable. A "T4P" insignia is usually present on the turntable to indicate a P-mount tonearm. So, for all practical purposes any brand below will fit and work in a T4P tonearm. The cartridge brand does not have to match the turntable brand. A P-mount cartridge is usually found on linear tracking tonearms which are the ones that slide from side to side. This rule is sometime broken is they are also found on some gimble base straight tonearms.
