KeepIS recently advised me to say that the HY5608's are currently on the endangered list and LCSC has run dry. Apparently, there are other suppliers, but they are charging a lot more and my best advice is to steer well clear of other Vendors.
My track record of buying semiconductors from Ali Express is that they are nearly all fakes and if you do find some genuine product, someone over there made a serious mistake. They must roll around laughing each time some poor sucker orders their semiconductors, rather fitting "semi" meaning almost, but not quite the real thing.
There are other devices from LCSC that could be considered. First for the Variac power PCB the old HY4008 is quite suitable for typical Variac applications up to 1kW and should handle peaks of 2 - 2.5kW without issue.
The list of substitutes where there is currently stock available from LCSC at the time of posting is below. Please note that I have only tested HY5608's and HY4008's the ranking I used below were based on specifications from highest to lowest preference. For the 48 volt types 1) to 5) and even 6 are probably good choices for a 5KW inverter.
There are also devices very suitable for 24V systems such as:
1)---SE40300GTS--------40V---288A---2.0 mOhm---$1.00 @ 30 off
2)---HY4504W-------------40V---250A---2.4 mOhm---$0.99 @ 30 off
For 48 volt systems
1)---HY5608W-------------80V---360A---1.5 mOhm---$1.42 @ 30 off (currently nil stock) I have emailed them re lead time
2)---HY5208W--------------80V---320A---2.0 mOhm---$1.34 @ 30 off
3)---HY5110W-------------100V--295A---2.4 mOhm---$1.41 @ 30 off
4)---Hy5012W--------------125V--300A---2.9 mOhm---$1.34 @ 30 off
5)---GT016N10Q----------100V--288A---1.65mOhm---$1.25 @ 30 off
6)---SP010N02BGHTF---150V--235A---2.0 mohm---$1.20 @ 30 off
7)---SP010N03BGHTF---100V--210A---3.2 mohm---$0.67 @ 30 off
8)---HY4008W---------------80V---200A---3.5 mohm---$0.84 @ 30 off
