SC2723S Power IC

If a Samsung Galaxy J1, J2, Core Prime, or Core 2 comes into your shop completely dead, not charging, or stuck at a black screen with no current draw on the power supply, the SC2723S power IC is one of the components you check before condemning the board. This PMIC sits on Spreadtrum-based Samsung boards and handles the core power distribution that every other component on the board depends on. Without a working power IC, the CPU never gets a clean power sequence, and the phone stays dead no matter what software you flash.Technicians working on these older Galaxy models know the pattern. A phone that was dropped, exposed to moisture, or came in after a failed charging attempt often shows a short on the battery connector or the power rail. You isolate the short with a bench power supply, and if the short traces back to the power IC footprint, reballing or replacing the chip is usually the fix. This is exactly where the SC2723S comes in as a direct board-level replacement.On your repair bench, this chip is relevant across a specific set of boards. It shows up on the Samsung Galaxy J1 (SM-J100H), Galaxy J1 Mini and J1 Nxt (SM-J105x series), Galaxy Core Prime (SM-G360H), Galaxy Core 2 (SM-G355H), and Galaxy J2 (SM-J210F). These boards share the same Spreadtrum power architecture, which is why the same PMIC part number turns up across what looks like unrelated Galaxy models on paper. Before you commit to a chip change, always cross-check the exact board revision against a working donor or a verified schematic, since board revisions inside the same model number can differ.Removing and installing this IC needs a proper hot air rework station with accurate temperature control, since these boards use lead-free solder and the surrounding components are heat-sensitive. Preheat the board evenly, use the correct nozzle size to keep hot air localized on the IC footprint, and clean the pads thoroughly before reballing. A fresh stencil for the SC2723S footprint keeps ball placement accurate and cuts down on rework. Technicians who skip the preheat step or run air temperature too high often end up lifting nearby pads, which turns a straightforward IC change into a much bigger board repair.Before ordering, confirm the fault is genuinely IC-related and not a cracked solder joint, a bent connector pin, or a liquid-damage corrosion issue elsewhere on the board. A quick continuity check on the power rail and a visual inspection under a microscope will save you from an unnecessary chip change. Once you've isolated the fault to the power IC itself, this chip gives you a direct path to bring a dead board back online without waiting on a full motherboard swap.For shops in Lahore, Karachi, and Islamabad running high volumes of Samsung board repairs, keeping the SC2723S in stock alongside your reballing stencils and flux means you're not stuck waiting on a donor board every time a low-cost Samsung comes in dead. It's a small, inexpensive part that solves a repair that would otherwise mean replacing the entire motherboard.
