The 8-DSBGA supplier device package is the same footprint. Any replacement candidate must be pin-compatible or the board layout changes. The surface-mount DSBGA package is not suited for hand-soldering or rework without a hot-air station and stencil. The scorch mark on a dead board often points to a cracked solder ball under the package rather than a failed die. The 3 MHz switching frequency is relatively high, which lets the converter use small inductors and capacitors, but it also means the replacement must have a similar frequency range to keep the output ripple and transient response in the same ballpark. The 500 mA output current and 2.7 V to 6 V input range set the power budget. A replacement with lower current or narrower input range won't work; one with higher current may be overkill but still fit if the package matches. The fixed 1.8 V output and positive output configuration mean the regulator is not adjustable — any replacement must also output 1.8 V fixed, or the feedback network on the board must be changed.","metaTitle":"TPS62303YZDR Buck Regulator, 500 mA, 3 MHz, DSBGA-8","metaDescription":"Texas Instruments TPS62303YZDR step-down (buck) regulator, 500 mA output, 3 MHz switching, 2.7 V to 6 V input, fixed 1.8 V output, 8-DSBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-UFBGA, DSBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS623","Output Configuration":"Positive","Frequency - Switching":"3MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"-","Supplier Device Package":"8-DSBGA","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/664e85230a0dcba807f15e368bfeea9d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62303YZDR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS62303YZDR?","answer":"Texas Instruments has not listed an official replacement for the TPS62303YZDR.
