ISO7041-Q1: Difference between the Q1 and non Q1 version

Part Number: ISO7041-Q1
Other Parts Discussed in Thread: ISO7041,

Hi Team,

I noticed that the non-Q1 version of the ISO7041 has a wider temperature range compared to the Q1 version. Why is that? We would normally think that automotive grade devices should have the widest temperature range.

Other than that, are there any differences in specification that we should be aware of if we would like to multi-source these devices?

Thanks!

Roy

  • Hello Roy,

    Thank you for your question. The Q1 device undergoes additional testing to meet and qualify for the AEC-Q100 standard required by Automotive. The AEC-Q100 standard uses specific temperature ranges, and for temperature grade 1 devices like the ISO7041-Q1 the standard requires -40C to 125C, hence the smaller temperature range.

    You can expect the Q and non-Q variants to operate according to their individual datasheets. 

    I hope this helps.

    Best,

  • Hi Andrew,

    Thanks for the comment!

    Do you have a comparison between the Q1 and non-Q1 version of the ISO7041? I noticed that they have different supply voltage ranges and was wondering if there are anything else different?

    Thanks!

  • Hello Roy,

    Unfortunately, we do not have a comparison. As you have noticed, the supply range for the Q1 version is smaller. The smaller supply range is also due to the automotive qualification process. The devices are similar and share many commonalities. Please refer to the datasheet for specific information and details on device differences.   

    Best,
