Apple's original C89 is a USB-A to Lightning connector, and Apple's latest C189 connector is also a USB-A to Lightning connector. Among them, C89 is the model that replaces C48, and C94 is now the mainstream USB-C to Lightning connector. C189 is a low-end version of C89, supporting 12W power, and it is also worth noting that C189 and C89 can be used interchangeably in the same product, that is to say, the original C89 PPID can use C189 without re-authentication. 

Apple's latest C189 connector uses the same material and layout as the C94. Combined with this year's chip shortage and the delay in the delivery of the iPhone13 series, Apple's launch of the C189 new connector will unify the materials, which can reduce the pressure on the supply chain, and is also expected to upgrade the ruthenium-rhodium plating of USB-C to Lightning. The material process of the new C189 connector is the same as the current C94, so the unification of the material is the first step, and it is expected that Apple will have more big changes that have to be changed in the future, and it will be wait and see.
