AI Thread Summary
The discussion focuses on finding a suitable replacement for the AUIRLR2908 MOSFET, emphasizing the importance of key parameters such as breakdown voltage, Imax, and Rds-on for a drop-in equivalent. A suggested alternative is the FDD5690, which reportedly matches the required specifications. The conversation also highlights the need to consider automotive qualifications, specifically AECQ101, if the application is automotive-related. Participants clarify the importance of using the correct data sheet for accurate comparisons. Overall, ensuring compatibility with the original device's specifications is crucial for successful replacement.

TL;DR Summary
Trying to identify key parametrics when trying to find an equivalent MOSFET
I am currently in need of a MOSFET to replace the AUIRLR2908 I am currently using.
This power MOSFET is used in enhancement mode for switching.
The data sheet is attached for reference.

What are some of the key parametrics I should be concerned with when trying to find a drop in equivalent?

Thank you in advance.

Why can't you just use this part?
The data sheet you have attached is for a different part. Now I'm confused.

I think https://www.digikey.com/product-detail/en/on-semiconductor/FDD5690/FDD5690CT-ND/1626197 should work. Breakdown voltage, Imax, and Rds-on are all about the same. If not, Digi-Key has many other to choose from

This one is the actual part in question.

Thank you!
So Breakdown voltage, IMax and Rds-on are the key parameters I should look for?

Yes, I think those are the most important. If it is just functioning as a switch, those are what matter. If you are doing something more complex, then other parameters may matter.
 
The OP's original device is an AECQ101 part, kind of need to keep the automotive qualification part if going into an automotive application.

I'm assuming this is for a personal project and not work related?
