What each comparison means (5)
- TDK SPM5030T-R47M-HZ (SPM5030T-HZ): Same inductance, 0.47 µH vs MAZO 0.47 µH. Saturation current 11 A (20% drop) vs MAZO 18 A typ. (30% drop), rated on different bases so not directly comparable; heating current 14 A (40 °C rise) vs MAZO 10 A typ. (40 °C rise). DCR 5.39 mΩ max vs MAZO 8.5 mΩ max. Body 5.2 × 5 × 3 mm vs MAZO 5.7 × 5.4 × 3 mm. Land pattern close to MAZO's: two 2.2 × 1.5 mm pads 2.7 mm apart vs MAZO two 2.5 × 1.9 mm pads 2.2 mm apart (gap differs by 0.5 mm). Verdict: MAZO figures are weaker, consider only with ample margin (Idc about 29% lower at 40 °C rise, DCR slightly higher). Before switching, verify brands define Isat/Irms differently: check the real peak current and allowed temperature rise, the land pattern against both drawings and test samples. Both parts are AEC-Q200.

Verdict: replaceable with design margin, pads need checking (Idc about 17% lower at 40 °C rise, DCR slightly higher).

How the figures are compared
Isat and Irms follow each datasheet's own definition, shown after the figure. MAZO figures are typical values from its spec table.
Recommended pads: pad width × pad length, then the gap between the two pads, from each datasheet, compared with MAZO's.
Same footprint, other values
Same 5.7 × 5.4 mm body, by inductance. Check the height before swapping.

Selection and use
How to select
Choosing inductance
L ≈ (Vin − Vout) × Vout ÷ (Vin × fsw × ΔI), with ΔI at 20–40% of the output current. The series covers 0.33–10 µH in one body, so changing the value needs no new layout.
Saturation current Isat
the current at which inductance falls about 30%; keep the peak current below it.
Heating current Idc
the current that raises the part about 40 °C above a 25 °C ambient; ambient plus rise stays within 125 °C.
DC resistance
sets the conduction loss. Typical 4.5–110 mΩ across the series; use the maximum for loss budgets.
Rated voltage
50 V maximum; check it against the input voltage.
Height
Max 3.0 mm. Lower: VCMA-0420; same height, more current: VCMA-0630.
