These spare parts are charging connector modules, which include the micro USB (or the relevant connector type for the phone) mounted on a small flex or PCB.
They connect to the mainboard of the phone via solder pads or a flex connector.
The module typically includes power pins (V+, GND) and data pins (D+, D−) for USB/data.
They are often silver in color (metal shell) — that’s likely what you meant by “silver OG CC.”
When replacing, the new part must match the pin layout, mounting holes, and dimensions exactly to avoid damage or misalignment.
