Tilt Latch replacement

Hello,
I have a window I need replacement tilt latches. The pic with the latches, the ones I ordered off amazon are on the left (white) and don't fit even though it ordered the size. The ones on the right (off-white) are from my window which need replacement. They had cracked when I had been removing them from the window bc they were brittle.

The distributor of these windows were Rosenello's but I don't know the manufacturer of the windows.
