TPS3840: Difference between TPS3840DL28DBVR and TPS3840DL28DBVRQ1

Keigo Shimada

Part Number: TPS3840

Hi team,

Our customer considers to use TPS3840DL28DBVRQ1 as alternative for TPS3840DL28DBVR.

Could you give us comment on the following questions?

1. Is TPS3840DL28DBVRQ1 identical with TPS3840DL28DBVR in terms of internal structure and material?

2. I think the only difference between them is testing process, is that correct?

Best regards,

Hi Shimada,

This is a public forum so there is a limitation on what we can share.

1. You can compare both device materials using the sites below

They seem to match which increases my confidence that they are the same.

2. The Q1 does have additional tests as per the aec q100 qualifications

There is no issue when using the Q1 as an alternative to the non Q1.
