FAQ LAN Transformer: WHDH12401N0

Can WHDH12401N0 replace WHD12401G directly because their main dimensions are similar?

›

A direct replacement cannot be assumed. Available model-level information gives both parts a 13.05 mm × 7.80 mm body, 12 pins, 2.00 mm pitch, 5.00 mm row spacing, and similar electrical limits, but it does not define the part-number difference or substitution relationship. Technical team confirmation is required. The preliminary assessment is based on their similar mechanical and electrical conditions; formal substitution must still be controlled by approved drawings, specification revisions, samples, and change approval.

How should the 7.50 mm maximum height and 3.00 ± 0.50 mm lead protrusion of WHDH12401N0 be handled in the library model?

›

Use a 13.05 ± 0.50 mm × 7.80 ± 0.50 mm body, 2.00 mm pin pitch, 5.00 mm row spacing, 10.00 ± 0.20 mm longitudinal span, and 0.90 mm recommended hole diameter for the PCB footprint. Retain the 7.50 mm maximum height and 3.00 ± 0.50 mm lead protrusion in the mechanical model, and check top-side clearance, PCB thickness, and solder-side fixtures.

How should engineering acceptance of WHDH12401N0 cover both magnetic and isolation performance?

›

For magnetic performance, verify the minimum 350 μH open-circuit inductance at 100 kHz, 0.1 V, and 8 mA bias, maximum 0.5 μH leakage inductance, maximum 1400 mΩ DC resistance, and 1CT:1CT ±5% turns ratio. For isolation, use the 1500 VAC, 1 mA, 60 s dielectric withstand test. The dielectric value is a test condition, not a continuous operating voltage.

What Certifications Does VOOHU Hold?

›

VOOHU is certified to ISO 9001:2015 and ISO 14001:2015 standards. Our products comply with RoHS, REACH, and CE requirements, ensuring high quality, environmental compliance, and reliable performance for global markets.
