What each comparison means (4)

Cyntec CMLB135T-220MS: Same inductance, 22 µH vs MAZO 22 µH. Saturation current 6.6 A (30% drop) vs MAZO 8.2 A typ. (30% drop); heating current 5.5 A (40 °C rise) vs MAZO 6.5 A typ. (40 °C rise). DCR 58 mΩ max vs MAZO 39.5 mΩ max. Body 13.45 × 12.6 × 4.8 mm vs MAZO 13.8 × 12.9 × 5 mm, MAZO 0.2 mm taller. Same land pattern as MAZO (two 5 × 3.25 mm pads 8 mm apart). Verdict: drop-in candidate (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, height clearance and test samples.
Bourns SRP1245A-220M: Same inductance, 22 µH vs MAZO 22 µH. Saturation current 10 A (20% drop) vs MAZO 8.2 A typ. (30% drop), rated on different bases so not directly comparable; heating current 6.5 A (40 °C rise) vs MAZO 6.5 A typ. (40 °C rise). DCR 58 mΩ max vs MAZO 39.5 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: 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, height clearance, the land pattern against both drawings and test samples. Both parts are AEC-Q200.
Bourns SRP1245CC-220M: Same inductance, 22 µH vs MAZO 22 µH. Saturation current 11 A (30% drop) vs MAZO 8.2 A typ. (30% drop); heating current 7.5 A (40 °C rise) vs MAZO 6.5 A typ. (40 °C rise). DCR 58 mΩ typ vs MAZO 34.5 mΩ typ. 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: MAZO figures are weaker, consider only with ample margin (MAZO Isat about 25% lower, Idc about 13% 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.

(40 °C rise), rated on different bases so not directly comparable. DCR 24.7 mΩ typ vs MAZO 34.5 mΩ typ. Body 13 × 12.8 × 6.2 mm vs MAZO 13.8 × 12.9 × 5 mm, MAZO 1.2 mm lower. Land pattern differs from MAZO's: two 5 × 4.5 mm pads 6 mm apart vs MAZO two 5 × 3.25 mm pads 8 mm apart (gap differs by 2 mm). Verdict: MAZO figures are weaker, consider only with ample margin (MAZO Isat not lower, 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

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.
