What each comparison means (5)
- Bourns SRP4020TA-R56M: Same inductance, 0.56 µH vs MAZO 0.56 µH. Saturation current 10 A (20% drop) vs MAZO 10.5 A typ. (30% drop), rated on different bases so not directly comparable; heating current 7.3 A (40 °C rise) vs MAZO 8 A typ. (40 °C rise). DCR 16 mΩ max vs MAZO 13 mΩ max. Body 4.45 × 4.06 × 2 mm vs MAZO 4.75 × 4.45 × 2 mm. Same land pattern as MAZO (two 2.5 × 1.5 mm pads 2.2 mm apart). Verdict: drop-in candidate (Idc not lower at 40 °C rise, DCR lower, less conduction loss). Before switching, verify brands define Isat/Irms differently: check the real peak current and allowed temperature rise and test samples. Both parts are AEC-Q200.
- Coilcraft XFL4020-561MEC: Same inductance, 0.56 µH vs MAZO 0.56 µH. Saturation current 6.3 A (30% drop) vs MAZO 10.5 A typ. (30% drop); heating current 13 A (40 °C rise) vs MAZO 8 A typ.

Verdict: MAZO figures are weaker, consider only with ample margin (MAZO Isat not lower, Idc about 38% 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.

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 4.75 × 4.45 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 0.1–10 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 3.5–245 mΩ across the series; use the maximum for loss budgets.
Rated voltage
40 V maximum; check it against the input voltage.
Height
Max 2.0 mm. For more current, VCMA-0530 or VCMA-0630.
