Which kind of FPC can be replaced by FFC?

FFC (flexible flat cables) are a type of ribbon cable, so named due to their wide flat structure. They are usually a straight connector, without any additional components. The lines are straight and the spacing is fixed.

FPC is made of polyimide material and etched copper conductors. FPC can accept more severe tolerance than FFC and is also available in 0.3mm thick versions. There are many different kinds of FPC, including single layer, double-sided, multilayer flex circuits.

The cost of FFC will be much lower than FFC, and the flexibility and connectivity are almost same. Normally the FFC are used in plug connectors, there are golden fingers on both side, golden finers can be in different directions; all traces are straight and the spacing is fixed, like below picture. If your FPC project is similar to this design, no component needed, then you can design it as a FFC.
