    I need to change a few blown components from a charger, but I can't seem to get the exact ones.
    The MBR5200 diode with datasheet: https://www.diodes.com/assets/Datasheets/MBR5200.pdf
    can I use this one?

    And also I have a resistor which in my opinion must be at least 1W or 2W it is 0,43Ohm 5% (yellow, orange, silver, gold) but what is the exact wattage the size is approximately 11x4,3mm.

    Could someone tell me if the diode is good, and what wattage is the resistor if you could determine it.

    Can you post some pictures of what you are working on?

    HER503 - 508 should be usable. A 4 x 11 mm or 5 x 11 mm resistor is most likely a 1W, but if there is room replacing it with a 2W would not be a bad idea.

    It is a battery charger for Ryobi cordless tools.

    The diodes are where there are two empty holes, and the resistor is behind the heatsink.

    So I found some MBR5200 diodes (the exact ones) they are a bit pricey, but I will go with them, as for the resistors I just bought a few 1W and 2W resistors so I will see which ones I can fit in.

    The diode is a 5amp 200v type, as for the images, site won't open so we can't see them.

    I just tried to open the page in a few browsers and it opens correctly, so no idea as to why you can't open it (the link is to a folder with photos in my cloud storage)
