Hi, your current i3-8100 has a TDP of 65W, while your new i5-9400F will be around 95W. Your AsRock H310M-DGS motherboard supports up to 95W, so it should work fine. Since you're budget-conscious and want to avoid buying another motherboard, it's a good idea to stick with the same one.
It functions properly as long as you install the newest BIOS; the main concern is that the key here is updating to keep performance stable. The word "work" appears frequently, and this model isn't ideal for high-end builds—though a 2.9GHz base should still run without major issues. If you're comfortable with lower speeds, it should perform adequately.
It's possible I'm mistaken about the boost clock rating; if it's moderate, the board should work fine.
Locked i5 will hold up. The VRMs won’t slow down until about 100°C, which should happen around that temperature if airflow stays decent. I’d go ahead unless the price isn’t right. If you can snag a Ryzen 5 2600 with a B450 for no more than 50% above the 9400’s cost, I’d choose the Ryzen version. Right now in the US, a 9400F is about $200, a 2600 is around $120, and a good B450 is $100. In this scenario, the 2600 seems more sensible.
