What each comparison means (5)
- Vishay IHLP2525CZER8R2M01 (IHLP-2525CZ-01): Same inductance, 8.2 µH vs MAZO 8.2 µH. Saturation current 7.5 A (20% drop) vs MAZO 5.8 A typ. (30% drop), rated on different bases so not directly comparable; heating current 4 A (40 °C rise) vs MAZO 4.5 A typ. (40 °C rise). DCR 68 mΩ max vs MAZO 60 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: 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, the land pattern against both drawings and test samples.
- Bourns SRP6530A-8R2M: Same inductance, 8.2 µH vs MAZO 8.2 µH. Saturation current 7.5 A (30% drop) vs MAZO 5.8 A typ. (30% drop); heating current 5 A (40 °C rise) vs MAZO 4.5 A typ. (40 °C rise). DCR 68 mΩ max vs MAZO 60 mΩ max. Body 7.1 × 6.6 × 3 mm vs MAZO 7.3 × 6.8 × 3 mm. Land pattern differs from MAZO's: two 3.4 × 1.85 mm pads 3.7 mm apart vs MAZO two 3.5 × 2.35 mm pads 3.7 mm apart (overall span differs by 1 mm). Verdict: replaceable with design margin, pads need checking (MAZO Isat about 23% lower, Idc about 10% 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.
- Cyntec VCMV063T-8R2MN2T (VCMV063T MN2TM / MN2T): Same inductance, 8.2 µH vs MAZO 8.2 µH. Saturation current 6.7 A (20% drop) vs MAZO 5.8 A typ. (30% drop), rated on different bases so not directly comparable; heating current 4.5 A (40 °C rise) vs MAZO 4.5 A typ. (40 °C rise). DCR 74.4 mΩ max vs MAZO 60 mΩ max. Body 6.95 × 6.6 × 2.8 mm vs MAZO 7.3 × 6.8 × 3 mm, MAZO 0.2 mm taller. Land pattern differs from MAZO's: two 3.5 × 3.3 mm pads 1.8 mm apart vs MAZO two 3.5 × 2.35 mm pads 3.7 mm apart (gap differs by 1.9 mm). Verdict: replaceable with design margin, pads need checking (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, height clearance, the land pattern against both drawings and test samples. Both parts are AEC-Q200.
- Coilcraft XGL6030-822MEC: Same inductance, 8.2 µH vs MAZO 8.2 µH. Saturation current 6.5 A (30% drop) vs MAZO 5.8 A typ. (30% drop); heating current 7.1 A (40 °C rise) vs MAZO 4.5 A typ.

Land pattern differs from MAZO's: two 5.5 × 1.43 mm pads 2.61 mm apart vs MAZO two 3.5 × 2.35 mm pads 3.7 mm apart (overall span differs by 2.93 mm). Verdict: MAZO figures are weaker, consider only with ample margin (MAZO Isat about 11% lower, Idc about 37% 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 7.3 × 6.8 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 0.22–22 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.
