This footprint is not hand-solderable; board assembly requires a stencil and reflow oven.
Switching frequency shrinks the passives
That is the whole point of this part: a tiny power supply for a tight PCB layout. The 500 mA output current covers low-power loads like sensor modules, RF transceivers, or auxiliary rails in battery-powered gear.
No official successor part is published in the lifecycle record. New designs should not target this order code; replacement candidates must be evaluated from the TPS623 family or a pin-compatible alternative. Availability is limited to surplus and broker inventory.
