TL074: Difference between TL074MJB and TL074MJ

Part Number: TL074

Dear,

I want to buy TL074MJ for their project, but inventory is out of stock now. I heatd that this is hot market.

I understand that they are two different P/N products, but I want to know their functional differences.

 

According to the data sheet, I think both are the same product but differ in one thing.

Last time I received the answer from TI support team that ‘TL074MJB is a QML part which goes through additional tests and processing per MIL-PRF-38535 while the TL074MJ does not.

I also checked the SMD she mentioned, but still don't understand.

We need to know detail about this MIL-SPEC based specific test only performed in TL074MJB since we have to decide whether this product is technically and functionally viable as a replacement for TL074MJ.

 

In ordering and quality page, I cannot know the detail about their difference.

Please inform this to technical team, please let me know their detailed difference.

Thank you.

 

Best regards,

Danny

  • The datasheet is written by TI and lists the specifications that TI guarantees.
    The SMD is written by the DoD and lists the specifications that devices are required to conform to. (The same SMD might be for multiple devices from different manufacturers.)

    For the TL074MJ, the datasheet applies.
    For the TL074MJB, the datasheet and the SMD apply.
    The TL074MJB is fully backwards compatible with the TL074MJ.

  • Thank you for your response.

    I think my question is still unanswered. 

    As I mentioned, last time I received the answer from TI support team that ‘TL074MJB is a QML part which goes through additional tests and processing per MIL-PRF-38535 while the TL074MJ does not.

    I need to know detail about this MIL-SPEC based specific test only performed in TL074MJB since we have to decide whether this product is technically and functionally viable as a replacement for TL074MJ, and need data on how the two products are different.

    Please check and let me know. Thanks in advance.

  • Dear,

    Regarding TL074MJB, please see the link https://www.ti.com/quality-reliability-packaging-download/report?opn=TL074MJB.

    The qualification summary has no result found. Can you please check and provide it? because I want to compare with TL074MJ, please see the link that TL074MJ has qualification summary. https://www.ti.com/quality-reliability-packaging-download/report?opn=TL074MJ.

    Please advide.

  • Hello Danny,

    TL074MJB conforms to the SMD on the product page. This will provide the information on the qualification of the device.

  • Dear,

    I am sorry, it would be appreciated if you can answer more specific.

    I have checked SMD, but I still cannot find that what kind of specific test if performing to TL074MJB. Please explain.

    Also, I asked that 'since we have to decide whether this product is technically and functionally viable as a replacement for TL074MJ, and need data on how the two products are different.' Please advise.

    What I understood was TL074MJ and TL074MJB is functionally same product, but only difference is TL074MJB perform extra test that TL074MJ doesn't. Is it right?

    Please check and let me know.

    Thank you.

  • Hey Danny,

    The qualification report of the TL074MJ details the test procedures for the part. Similarly, Section 4 of the SMD details the testing that is performed on the TL074MJB.

    Because the SMD is a military document, I'm unsure of how much I am allowed to share on a public forum, so I will speak in general terms. The general difference between devices with a qualification report and the MIL spec parts is that the MIL spec parts will undergo a burn-in test to screen out early life failures. Usually the devices qualified by TI will have some devices go through a series of tests when the part is first being qualified, then instead of putting every device through a life-test, we test the electrical characteristics after the part has been manufactured.

    I apologize for being unable to share more specifics, but the SMD outlines very exactly what tests must be performed and to what standard in Section 4. Unfortunately it does this through referencing other specifications. I have provided them below for convenience.

    I will inquire internally and ask how much, if any, of the information I am allowed to share.

    Best,
