What each comparison means (5)
- Bourns SRP4020TA-R22Y: Same inductance, 0.22 µH vs MAZO 0.22 µH. Saturation current 24 A (20% drop) vs MAZO 18.5 A typ. (30% drop), rated on different bases so not directly comparable; heating current 11 A (40 °C rise) vs MAZO 12 A typ. (40 °C rise). DCR 7.3 mΩ max vs MAZO 5.6 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: replaceable with design margin (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.
- Vishay IHLP1616BZERR22M01 (IHLP-1616BZ-01): Same inductance, 0.22 µH vs MAZO 0.22 µH. Saturation current 24 A (20% drop) vs MAZO 18.5 A typ. (30% drop), rated on different bases so not directly comparable; heating current 13 A (40 °C rise) vs MAZO 12 A typ. (40 °C rise). DCR 8.6 mΩ max vs MAZO 5.6 mΩ max. Body 4.06 × 4.45 × 2 mm vs MAZO 4.75 × 4.45 × 2 mm. Land pattern close to MAZO's: two 2.286 × 1.855 mm pads 1.93 mm apart vs MAZO two 2.5 × 1.5 mm pads 2.2 mm apart (overall span differs by 0.439 mm). Verdict: replaceable with design margin (Idc about 8% 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.
- Cyntec VCHA042A-R22MS62M (VCHA042A MS62M): Same inductance, 0.22 µH vs MAZO 0.22 µH. Saturation current 13.7 A (30% drop) vs MAZO 18.5 A typ. (30% drop); heating current 11.4 A (40 °C rise) vs MAZO 12 A typ. (40 °C rise). DCR 6.4 mΩ max vs MAZO 5.6 mΩ max. Body 4.2 × 4 × 2.1 mm vs MAZO 4.75 × 4.45 × 2 mm, MAZO 0.1 mm lower. Land pattern close to MAZO's: two 2.286 × 1.855 mm pads 1.93 mm apart vs MAZO two 2.5 × 1.5 mm pads 2.2 mm apart (overall span differs by 0.439 mm). Verdict: the figures qualify, but the pads need checking (MAZO Isat not lower, 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 3.4 × 0.98 mm pads 1.39 mm apart vs MAZO two 2.5 × 1.5 mm pads 2.2 mm apart (overall span differs by 1.85 mm). Verdict: MAZO figures are weaker, consider only with ample margin (MAZO Isat about 1% lower, Idc about 29% 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 3.8 × 1.2 mm pads 1.25 mm apart vs MAZO two 2.5 × 1.5 mm pads 2.2 mm apart (overall span differs by 1.55 mm). Verdict: MAZO figures are weaker, consider only with ample margin (MAZO Isat about 24% lower, Idc about 40% 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.
