Description

SN2012027-A33 is a U2 Charging IC used for motherboard-level charging circuit repair on the iPhone 16 Series.

It is intended for professional board repair and microsoldering work when the original charging IC requires replacement, including charging-circuit and USB-C related faults. Specialized parts suppliers identify the SN2012027 A33 version for the iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max.

A33 Version

This component is the A33 version of SN2012027. Repair references distinguish the versions used across generations: iPhone 15 uses SN2012027 A12, while the iPhone 16 series uses SN2012027 versions including A23 and A33. Selecting the correct IC version is therefore important before replacement.

Important Technician Note

The charging circuit on iPhone 15/16 platforms works together with an 8N EEPROM containing charging-related data. If the original EEPROM data remains intact, the U2 IC may be replaced separately in applicable repairs. If the EEPROM data has been lost, a programmed EEPROM may also be required. This listing refers to the SN2012027-A33 U2 IC only unless an EEPROM is explicitly included in the supplied package.
