Inspiron 1764 motherboard 0F1R94 broken, replace with YWY70?

My motherboard is broken on my inspiron 1764, i can see on the internet that DP/N YWY70 should work in the inspiron 1764 but when i open my machine i find a DP/ 0F1R94. When I search google I find this part number is mainly used with another laptop model, so my question is if I get a YWY70 will it work?

The CPU on my machine is i5 apparently. 

Thanks
