Charging pin compatibility guide in Spanish, a 2.03 MB PDF that presumably groups phones sharing the same charge connector or flex. No models or brands appear in the file name, so the coverage must be checked by opening it in any PDF reader. Repair shops rely on these lists to source a usable part from stock when the exact one is missing. Before fitting, compare connector type, pin count, pitch and mounting footprint with the original, and confirm the flex cable length and alignment if the port is mounted on a sub-board.
