First of all, I need explain what is equivalent and original type.
Eqvivalent, also called Chinese replacement, including connector, terminal, wire and cable, etc. It is produced by Chinese factory with the same specificaitons as original's. Its quality is not as good as original one, which are produced by TE, Molex, JST, JAE, and so on. However, because of its low price and fast delivery lead time, it is becoming many company's fisrt choice. But then again, Chinese brand are now attach great importance to the quality, they could also provide very good quality products are original ones.
Nowadays, more and more Chinese equivalent become famous, take Hulane for example. Many European and USA prefer to use hulane connector, instead of original one. Sometimes customer sends me the drawing with hulane P/Ns. We can see that how influenced hulane connector is.
Origial, referred to the TE, Molex, JAE, JST, etc.They are famous all over the world for its high quality. Customer always feel safe when they use original connector to assembled their products.
Generally speaking,not all the original connector has equivalent one. But molex and TE has more equivalent ones,compared to other brands.Using equivalent or original type, it depends on you. You are welcomed to send us inquiry with draiwng or specifications.
