LSM6DS3TR Obsolete Drop-In-Replacement

MatthiasH · ‎2025-06-23

Hi All,

I am working on a design that has been working for years.

Now we wanted to design a revision of the PCB with the LSM6DS3TR but sadly it became obsolete and I can't find it back on the website of ST.
Could the LSM6DS3TR-C be a Drop-In-Replacement for this part or another type?

Thanks in advance & kind regards,

The LSM6DS3TR-C is a drop-in replacement for the LSM6DS3TR, but differs in several parameters and is almost the same age as the LSM6DS3TR, so I can't recommend it as a replacement. It is also questionable whether the LSM6DS3TR-C is available in some regions of the world.

Instead, you can take a look at the LSM6DSO, which is also pin-compatible, but has a heavily modified register set, which is why the software has to be changed for it.

Hope that helps?

LSM6DS3TR is a good choice for designing with it.
