No, the other one.
A yandere isn't necessarily a stalker. Just crazy one way or another, and may or may not actively try to eliminate other suitors for their target. Can be any gender.

Basically a Yandere is usually violent but doesn't necessarily stalk, while a Stalker with a Crush isn't necessarily violent but does stalk.
They can totally overlap, though.

If a tree falls in the forest and nobody remembers it, who else will you have ice cream with?
A Yandere is the type to go at their love interest or love interest's love interest with a chainsaw.
A stalker with a crush is just that a stalker with a crush.
A person can be both but it isn't exclusive. Take the first episode of Renai Boukun the main girl is a Yandere, even called that by name, with her weapon of choice being Gurkha Knives and the main guy is the Stalker with a Crush... and then it gets weird.
Reading both Trope descriptions, I don't get the difference between them. Except that Yandere seems to generally (only?) refer to female examples, while a Stalker with a Crush can be both male or female but more often is male?
