Push-Pull Transformer Selection Comparison: VOOHU WHST06Q02E0 vs. Würth Elektronik 750316819
Push-Pull Transformer Selection Comparison: VOOHU WHST06Q02E0 vs. Würth Elektronik 750316819
1. Competitor Product Overview (Würth Elektronik)
Würth Elektronik 750316819 belongs to the WE-PPTI push-pull transformer series for compact isolated DC/DC supplies. It uses a 1208, six-pin SMT package with center-tapped windings; its typical reference point is 5 V input, 12 V output, 460 mA, and 400 kHz. In a push-pull design, turns ratio, volt-second capability, winding polarity, and PCB land pattern should be considered together.
2. VOOHU Replacement Overview (Suzhou VOOHU Electronic Technology Co., Ltd.)
VOOHU WHST06Q02E0 is a 1CT:2.88CT, six-pin SMT push-pull transformer with 86 µH open-circuit inductance, 2500 VAC isolation test voltage, and a −40°C to +125°C operating range. Its package outline and recommended land pattern can be compared dimension by dimension with 750316819, making it a candidate for evaluation in the same class of power supply. Schematic, PCB, and sample validation are still required before production release.
3. Key Parameter Comparison
The table preserves comparable values and their respective test conditions so the circuit and PCB fit can be evaluated together. DCR and volt-second entries that use different definitions are intentionally not ranked side by side.
| Parameter | Würth Elektronik 750316819 | VOOHU WHST06Q02E0 |
|---|---|---|

Notes:
- Both parts use the 1-2-3 and 6-5-4 center-tapped winding arrangement, and the outline and land-pattern dimensions can be matched item by item. That makes WHST06Q02E0 a candidate for PCB-level evaluation; it is not a proven pin-to-pin replacement until schematic polarity, PCB lands, and assembled samples are confirmed.
- The listed volt-second values are 9 Vµs and 15 Vµs. Together with switching frequency, duty cycle, and drive waveform, they determine flux margin; use the measured waveform for the design calculation rather than drawing a conclusion from one number.
- AEC-Q200 Grade 1 is listed for 750316819 only. It is not presented as an equivalent WHST06Q02E0 item in this comparison, and automotive programs should complete their own requirement-based validation.
4. Applications
- Isolated 5 V-to-12 V auxiliary supplies or gate-driver bias supplies, using the 400 kHz reference design as a starting point.
- Space-constrained push-pull power boards using a 1208, six-pin SMT layout, after confirming the recommended lands and pin polarity.
- Replacement evaluation, second-source introduction, or sample validation on an existing 750316819 design: complete PCB/CAD overlay first, then check input/output behavior, dielectric withstand, temperature rise, and EMI.
5. FAQ
Can WHST06Q02E0 be used as a direct replacement for 750316819?
The package outline, land-pattern dimensions, turns ratio, open-circuit inductance, and leakage inductance can be compared item by item, making it suitable for replacement evaluation. Those comparable values do not replace schematic-polarity review, PCB overlay, dielectric testing, and system-level sample validation, so this is not a pin-to-pin compatibility claim.
Can it be adopted directly for automotive work?
750316819 lists AEC-Q200 Grade 1, while this comparison does not present that as an equivalent WHST06Q02E0 item. Automotive use requires independent confirmation against the system reliability, certification, and customer requirements.
