(30% drop), rated on different bases so not directly comparable; heating current 13.8 A (40 °C rise) vs MAZO 14.5 A typ. (40 °C rise). DCR 7.22 mΩ max vs MAZO 6 mΩ max. Body 6.86 × 6.47 × 3 mm vs MAZO 7.3 × 6.8 × 3 mm. Land pattern close to MAZO's: two 3.429 × 2.413 mm pads 3.429 mm apart vs MAZO two 3.5 × 2.35 mm pads 3.7 mm apart (gap differs by 0.271 mm). 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, the land pattern against both drawings and test samples. Both parts are AEC-Q200.

Land pattern differs from MAZO's: two 3.5 × 2.95 mm pads 2.5 mm apart vs MAZO two 3.5 × 2.35 mm pads 3.7 mm apart (gap differs by 1.2 mm). Verdict: MAZO figures are weaker, consider only with ample margin (MAZO Isat about 47% lower, Idc not lower at 40 °C rise, DCR lower, less conduction loss).

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 0.22–22 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 2.5–175 mΩ across the series; use the maximum for loss budgets.
Rated voltage
75 V maximum; check it against the input voltage.
Height
Max 3.0 mm. More current: VCMA-1040; lower: VCMA-0420.
