Shimano 170mm FC-TY301 48/38/28 alternative
FC-TY501 is a straight swap according to Shimano's specs https://productinfo.shimano.com/#/lc/tourney/3x7, but you will need to get one the same chainrings you have now (e.g. 48/38/28 or 42/34/24).
Other options will work fine also, preferably those with 47.5mm chainline, but for proper front shifting either matching all three chainrings, or failing that smaller chainrings with the same gap and then move your front derailleur up/down, will be necessary.
