# What are these two smd components?

I fried these two components by plugging in the battery the wrong way. What are they? I read SMDs have an ID which helps identify them but since they are burned i cannot read the ID. If i replace them would it be possible to use a similar component?

• Both the parts are labelled Q-XX. Q is a letter commonly used for transistors. Similar to how R is for resistors Jul 10 '19 at 10:17
• If two transistors are broken with visible damage, there are probably more broken things on the board. How much is it worth to you to fix it? Jul 10 '19 at 10:25
