Electronic Components

[Sparkshower]

so i ordered some components from ali-express, blue disk shaped capacitors. Looking it up i find they are ceramic capacitors so i get the numbers form the old one (103M 1KV 19W), order them, wait, then today they came in the mail.
Well they look a bit different

It just doesn't look right i don't think technology has progressed that much since this TV was made, where did i go wrong?

The TDK ones Mouser sell have 7.5mm lead spacing and look very similar.
Is it thicker than the original one? It could be multilayer rather than single layer.

Or, something to do with the pulse current rating??
(Or it's possible they are dodgy, but it does not seem unreasonable to me).

The PCB has holes to take two different size components.
