Samsung Galaxy S21 Ultra 5G US Version Charging Connector compatible, designed for the American region (G998U). This part has been rigorously selected from validated third-party manufacturers and subjected to strict quality control before stocking. Unlike original manufacturer parts, it offers an economical alternative without compromising stability and reliability. The low return rate and batch traceability guarantee performance compliant with professional workshop expectations.

Warning: this US version (G998U) has a circuit board specific to American networks and Snapdragon processor. It is not compatible with the European version (G998B, Exynos). Check the exact model of your device before ordering to avoid any installation error. Covered by a 2-year warranty.

Why change the charging connector

The charging connector of the Samsung Galaxy S21 Ultra 5G undergoes the most intensive wear of any mobile device. Each plug-in, each unplug, each micro-movement of the cable puts stress on it: the contacts oxidize, the internal tabs bend, and over the months, the device stops recognizing the charger or charges intermittently. You notice that the phone only charges if you hold the cable a certain way, or that the unstable port threatens in turn to damage the charger's connectors.

Replacing the connector eliminates this problem and restores stable and fast charging to the Galaxy S21 Ultra 5G. It is a proven repair, far less costly than a new device, and extends the phone's life by several years.

Does this part fit my Galaxy S21 Ultra 5G

This connector is designed for the Galaxy S21 Ultra 5G US version (model SM-G998U), equipped with the Snapdragon processor and intended for North American markets. Check the exact reference of your device before ordering: it is found under the rear cover or in the phone's settings, under "About phone".

If your Galaxy S21 Ultra 5G bears the reference G998B, it is the European version with Exynos processor, which requires a different connector. The two versions have distinct internal circuits, and installing an unsuitable part would prevent any mobile network from functioning. Check your old part or your device's documentation to confirm the region.

A compatible part, inspected in the workshop

This connector is not an original Samsung part. It is a compatible part, manufactured by third parties to Samsung specifications. Unlike an OEM part recovered from an old device, it is new, and each batch undergoes strict quality control in the workshop: contact testing, mechanical stability verification, conductivity evaluation. Only parts that meet these criteria enter our inventory.

This approach enables a cost-effective repair without compromising reliability. You reduce replacement costs while obtaining a proven part, with a validated return rate and a 2-year warranty covering manufacturing defects.

Installation and checks before replacement

Installing a charging connector requires precision equipment: fine soldering iron, flux, lead-free solder, and an antistatic surface. It is a delicate operation that does not forgive mistakes: a short circuit destroys the motherboard, insufficient soldering leaves the connector unstable after a few weeks.

Before replacing, verify that the problem really comes from the charging port: test with another charger, clean the contacts of the device and cable with isopropyl alcohol. A simple residue can simulate a failure. Also confirm that your model bears the reference G998U on the internal label: any confusion costs the repair.

Warranty and conditions

This part benefits from a 2-year warranty against manufacturing defects. The warranty covers material and functional defects found in the workshop, not damage caused during installation or by abnormal use. Any incident occurring during desoldering or resoldering, or any subsequent degradation of the device, remains the responsibility of the technician.
