WHSG24701G Cross Reference
VOOHU WHSG24701G can replace Pulse Electronics H5004NL. See the evaluation reports below for details.

Based on VOOHU replacement evaluations. Check both datasheets and validate with samples before switching.
The WHSG24701G suits indoor Gigabit ports where the component temperature stays between 0 °C and +70 °C. Typical uses are the LAN ports of desktop switches and home routers, set-top box ports, office IP cameras and Gigabit management ports inside a rack. The WHSG24701G is a single-port, non-PoE 100/1000 BASE-T transformer, so the port has to be powered locally.
Where the equipment must power up below 0 °C or sit in an outdoor enclosure, move to the wide-temperature WHSG24701TG, which keeps the same land pattern and pin assignment. Other options are listed in the 100/1000 BASE-T range.
No. The datasheet assigns no DC balance current capability to the centre taps of the WHSG24701G, so the four MCT and TCT pairs cannot be used as a supply path. There is no current item among its eleven electrical entries. Terminate the centre taps according to the reference design for the target PHY.
Note that the 8 mA DC bias quoted on the OCL line is not a permitted load current – it is a direct current superimposed during the inductance measurement, so that the figure reflects the core with a DC component present. Where the port has to deliver power, take a part in the same package that carries a published current rating, such as the WHSG24702PG.
Decide on temperature: take the WHSG24701TG for -40 °C to +85 °C, or the WHSG24701G where 0 °C to +70 °C is enough and usually better on cost and availability. The two are electrically identical – same inductance, resistance, segmented insertion and return loss, crosstalk, common-mode rejection and isolation conditions – and neither carries a PoE current rating.
One difference is easy to miss: the WHSG24701TG is rated for storage to +125 °C where the WHSG24701G stops at +85 °C, which matters for projects with harsh warehousing. Switching between the two changes neither the electrical design nor the land pattern.
