What each comparison means (6)
- Bourns SRP1245A-R47M: Same inductance, 0.47 µH vs MAZO 0.47 µH. Saturation current 65 A (20% drop) vs MAZO 64 A typ. (30% drop), rated on different bases so not directly comparable; heating current 38 A (40 °C rise) vs MAZO 43 A typ. (40 °C rise). DCR 1.1 mΩ max vs MAZO 0.9 mΩ max. Body 13.5 × 12.5 × 4.8 mm vs MAZO 13.8 × 12.9 × 5 mm, MAZO 0.2 mm taller. Land pattern close to MAZO's: two 5 × 3.1 mm pads 8 mm apart vs MAZO two 5 × 3.25 mm pads 8 mm apart (overall span differs by 0.3 mm). Verdict: drop-in candidate (Idc not lower at 40 °C rise, DCR lower, less conduction loss).

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 13.8 × 12.9 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 0.22–33 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 0.54–50 mΩ across the series; use the maximum for loss budgets.
Rated voltage
75 V maximum; check it against the input voltage.
Height
Max 5.0 mm. VCMA-1365 shares the land pattern at 6.5 mm with more inductance; smaller: VCMA-1040.
