I don't know how you only found one surface mount bottom entry header... there's thousands of them ... see https://www.digikey.com/short/708d4jf1
instead of inline 5 also consider 2x3 or 2x4 arrangements as they'll also be more reliable, better for surface mount contacts , less chance of bending the header and lifting pads (due to mechanical shocks or other reasons)
yes there are a ton of them but i need 3.96mm pitch which is rare for some reason.
if you filter for 3.96mm and surface mount you find only 3 parts all of which are the same company, one of them is the part i listed.
alibaba supplier was good in contact and agreed to send the samples. the unit price for my quantity is just 0.185$ which cannot be beaten. this thing is a PSU which will connect to a board, 2 amps max so there should be no wear and tear or danger of any kind.
i actually once got a similar connector from another similar chinese company (CJT) for the same purpose but that one was through hole for my product (thunderpsu for dreamcst) and it was good and reliable.
i also looked into lcsc as usual but found nothing. all parts are "pre-order" with prices even higher than digikey.
the currently sampled part from china is exact same as the one from digikey so i will set the digikey one as alternative.
