No NRND or EOL notice to track — you can commit the BOM line without worrying about a looming last-time-buy window.
150 µF capacitance at 6.3 V with 125 mOhm ESR — the ESR is the number that tells you how much ripple current this part can handle before self-heating becomes a problem. For a 12 V rail stepped down to 3.3 V through a buck converter, the output capacitor sees a ripple current that depends on the inductor ripple and the duty cycle; 125 mOhm is low enough that a 1 A ripple current produces only 125 mW of internal dissipation, which the 2917 (7343 Metric) package can sink to the board without a thermal hotspot.
