hi guys..........can any body help me to find the allternate fet of mxp43p9a1?

 

Sites like digikey have an excellent parametric search.

You can get the parameters off of the current FET and search fairly easily.

A datasheet with the specs of the part that you're referring to would come in handy

About $2.88 in small quantities as I recall, but I've never used this distributor.
Please confirm MXP43P9AT, TO-220 case.
No help from Digi-Key parameter search.
IRL40B215 maybe. International rectifier, unless this is an automotive application.
