| Parameter | ||
|---|---|---|
| Supply voltage | - | Wider input window; modern low-Iq design point. |
| Memory & Peripherals | - | The forward path for new designs - and a board revision for existing ones. |
| Case | SOT-23-THIN-6 (DDC) | SOT-583 |
| Compatibility Level | - | Functional Equivalent |
| Component Category | Synchronous Buck Converters | - |
| Core & Architecture | - | TIs current recommended alternate: 3.8V to 30V input, 3A, lower quiescent current and higher switching frequency for smaller passives. |
| Firmware Notes | - | The honest sentence: the 62933 replaces the 54302 in a design review, not in a socket. SOT-583 is a different land pattern; where a repair needs the board to stay, stay on the DDC family. |
| Hardware Notes | - | SOT-583 against SOT-23-THIN-6 - different footprint. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The TPS54302 is the modern tiny buck of industrial and consumer boards - 4.5V to 28V input, 3A output, SOT-23-THIN-6, with the EMI spread-spectrum and light-load pulse-skipping that certificate-bound designs lean on. Inside the TI family the substitution is easy and documented: the 2A/3A/4A members are pin-to-pin. Outside the family the SOT-23-6 outline is a siren call - dozens of parts from six-plus manufacturers share the body, and very few survive the four questions that separate a functional replacement from a BOM line that fails EMI retest or drops out under light load. | - |
