what other transistor can i use in place of BS170??

 

For what?

As a paperweight, you can use ANY other.

 

What about 2n7000?

Allen

 

Note the BS170 is a MOSFET, not a simply a transistor in the classic use of the term.

In the quick Googling I did, Allen is right, a 2N7000 should work fine, but note the leads are in different locations. Should still be able to use by flipping the 2N7000 in the opposite direction if using a TO-92 package, but check the datasheets first.

The classic use of the term is irrelevant. A transistor is a transistor, a BJT is a transistor, as is a MOSFET, that's why it's in their names.

I just wanted to clarify for the OP the part inquired about is a MOSFET. I have found we often refer to BJTs on AAC as simply transistors and call out MOSFETs. While true both BJTs and MOSFETs are transistors, each operate differently.

That is why they need to be explicitly stated.

Saying transistor instead of BJT is plain lazy and makes for a confusing conversation. A new member will not know that distinction and may become more confused. As this is a site for learning and disseminating information, I think it pertinent to be explicit whenever possible.

The fact is that 'transistor' is a general term and should not be used to describe a specific device.

I don't say I want fruit juice, I say I want me some orange juice.

You are correct on all points. I couldn't recall the correct term for the commonly used transistor until you mentioned it (BJT). I've just seen the BJT transistor more often than not referred to simply as transistor on AAC. I will be sure for my part to make this distinction in the future.
