You can also just use Image if you are in Unity 2017.3 (not sure if this works for older versions). For example:

using UnityEngine.UI;
-----
public Image ObjectwithImage;
public Sprite spriteToChangeItTo;

void Start () {
        ObjectwithImage.sprite = spriteToChangeItTo;
    }

Works great for me.
