| FFF Compatibility | Uses the exact same 8-pin uSiP package (SIL0008E) with the identical pinout configuration.Identical mechanical dimensions and packaging (3.5mm x 3.5mm x 1.8mm).Output current capability is reduced to 650mA compared to 1A for the queried part. | Requires a board redesign due to a smaller footprint and completely different pin layout.Slightly smaller package size of 3.0mm x 2.8mm x 1.5mm but uses similar SMT integrated-inductor packaging.Matches the 1A output current, 17V maximum input voltage, and 0.9V to 6V adjustable output range. | ||
 AI Summary | LMZ21701SILT by Texas Instruments: Non-Isolated PoL Module DC DC Converter 1 Output 0.9 ~ 6V 1A 3V - 17V Input. | The LMZ21700 is the direct lower-current sibling from the same SIMPLE SWITCHER Nano Module family. It acts as an immediate physical and electrical drop-in replacement, provided the application's actual load current does not exceed 650mA. All external passive configurations and components remain identical.
| The TPS82150 is a more modern 1A, 17V step-down module from TI's MicroSiP family. It fully matches the electrical characteristics of the queried part but offers them in a more compact package. Due to the updated footprint and pinout, it requires a layout revision but serves as a high-performance active replacement.
