Resistor ordering help

[scotts530]

I'm having a hard time figuring out exactly what type of resistor to order. I'm trying to fix a hifonics hfi3000d. I need the resistors for r36 that connects to q12 irfp064n. Ithink the resistor is 47ohm 5% resistor . i get confused on digikey website. Would it be the 47 ohm 1/4watt 5% resistors. It's the 1/4 watt part I'm not sure about.

If the physical size matches that of the resistor you want to replace, it is probably the correct power rating.

Post #2:
Good advice. Unless the resistor is made of special materials, resistors of equal size are generally of equal power ratings.

In the attached image, resistors R236 and R237 are 1/4w. Resistors R286 and R287 are typically rated at 1/6 or 1/8w.
