Part Number: LM5166
Other Parts Discussed in Thread: DAC8775, LM5165, , TIPD215

Hi,

We are using LM5166QDRCTQ1 in one of our design with DAC8775 and presently LM5166QDRCTQ1 is shortage and needed very few qty for proto but still won't available, There is any alternate part for the same footprint and pinout or any possible best option?

Thanks in advance.

Hi Amit,

The part that has a pin to pin compatible that i know if is LM5165 but that is with lower output current

https://www.ti.com/product/LM5165

Otherwise, for the same specifications you may try this one also

Hi Amit,

Do you get the part from TI? it looks like we only have the non-automotive version released

Hi Arief,

This datasheet doesn't show this part no i.e., LM5166QDRCTQ1

I git this part no form DAC8775 EVK or TIDPD215.

LM5166QDRCTQ1 is fixed regulator or variable one?

Hi Amit,

The LM5166QDRCTQ1 should be an adjustable output version

Normally for fixed output, we have a suffix such as "X", "Y" or the actual output voltage.

I will double check internally about the availability for Q grade variants also

Thanks

Hi Amit,

After further checking internally, we do not release the Q grade variants for this product.

Thanks

Hi Arief,

https://www.ti.com/tool/TIPD215

Can you please see the Bill of material i the above link.

They too uses LM5166QDRCTQ1

I am still confused with this part i.e., LM5166QDRCTQ1

Hi Amit,

Yes they are using the adjustable version of LM5166 and the reference design should use the non-Q1 since it is not an automotive product. You can also see on the link above, if you scroll down you can see the TI device in the design refer to the LM5166

So just to summarize:

LM5166 --> Adjustable output --> Used in the TIPD215

LM5166X --> 5V Fixed output

LM5166Y --> 3.3 Fixed output

As you can see the X and Y is the differentiating between 3.3V output and 5V output.

Here are the complete orderable number
