Each magnetic channel supports 1.5 A of DC balance current, and the two channels of the single port together support 3.0 A – the highest current capability among the single-port parts in this range.The 3.0 A figure is the port total with all channels working together; it is not the rating of any individual coil, and it is not 1.5 A multiplied by the coil count. Match the WHSG24Z01C0 to your target PSE/PD scheme against the actual current draw.
Size four balanced paths at 1.5 A each rather than widening one path to 3.0 A.On the WHSG24Z01C0 the cable-side centre taps are MCT1 to MCT4 at pins 24, 21, 18 and 15, and the chip-side taps are TCT1 to TCT4 at pins 1, 4, 7 and 10. Concentrating the port total into one or two traces pushes the real current density well past the design intent. The +85 °C ceiling also already includes self-heating, so the copper and thermal design have to keep ambient plus self-heating within that boundary.
The pitch matches, the envelope does not: the WHSG24Z01C0 body is 19.90 mm × 13.00 mm with an 8.80 mm maximum height, noticeably larger than a conventional 24-pin Gigabit part.What it buys is 1.5 A per channel and 3.0 A full-channel current capability; what it costs is board area and height clearance. It cannot be placed on the basis of "also 24-pin, also 1.27 mm", and on low-profile products the 8.80 mm clearance has to be confirmed first. Other options are in the10/100/1000 BASE-T range.
