I broke the L1 button on my PS4 JDM-040 controller and this is the correct replacement part! As it comes with other knobs I now have spares for them just in case. Just make sure you have a JDM-040 controller. The springs needed for the L2 and R2 buttons are not included, which is something to note (the seller doesn't list them on the pictures, so not for your purchase). Just use the ones from your current controller if you still have them.
