LM5143-Q1: Need difference between 3 parts

Praven Kumar C J
Prodigy 195 points
Part Number: LM5143-Q1
Other Parts Discussed in Thread: LM5143, LM5143A-Q1

What are the difference between below 3 parts?

1. LM5143QRHARQ1: top marking LM5143QRHARQ1

2. LM5143QRWGRQ1: top marking LM5143A2

3. LM5143RHAR: top marking  LM5143RHAR

Is there any technical functionality difference between 3?. Can we still mount part 2 in part1&3's footprint.?. What does A2 refers to in part2?

Thanks in advance,

    Praven,

    All the parts should be interchangable, yes the footprint should be compatible for all three devices.

    LM5143RHAR and LM5143QRWGRQ1 are LM5143 and LM5143-Q1, just automotive version.

    LM5143QRHARQ1 is LM5143A-Q1, it is very similar specs as LM5143-Q1, just a different manufacturing plan so slight difference, and also same RHA package and LM5143.

    Hope this helps,
