TLE2426: Suitable Replacement

Marco Rojas
Intellectual 2060 points
Part Number: TLE2426

Hey team,

I got a customer inquiry regarding the TLE2426 that's going EOL for a suitable replacement. I'll copy the email below. 

"It appears the TLE2426 family is going EOL as stated on PDN 20230907001.3.  HME engineering was informed the automotive grade version, TLE2426QDRG4Q1, is still going to be produced.

I wanted to run this by you as this automotive grade version was not suggested as an alternate on the PDN.  Could you confirm this automotive grade PN is a suitable replacement and how long TI expects to support this part?"

Thanks in advance!

Marco

    Hello Marco,

    Yes, the TLE2426 family is in Last Time Buy Status and in the process of being discontinued.

    As you have mentioned, the TLE2426DRG4-Q1 automotive grade device is in active status and remains in production Please see the general Product life cycle information below: https://www.ti.com/support-quality/quality-policies-procedures/product-life-cycle.html

    The commercial grade device that is to be discontinued has different operating temperature conditions depending on the variant of the device.

    The automotive grade device operates for the temperature range of -40C to +125C.

     

    The automotive grade device is specified over the wider temperature range. When the automotive qualification is performed, the device is re-specified over the extended temperature range.  Some specifications such as the output voltage regulation are more conservative on the automotive grade device.

    Please review this post:

    Beyond this, we don't have an exact pin-to-pin replacement, other than to substitute with a discrete solution.

    I will refer you to the post linked below where we also recommended an alternative rail-splitter solution using a standard operational amplifier.

    Thank you and Regards,

    TI's EOL policy states a product will not be discontinued if any of these conditions exist:

    1. The product has had any sales within the last five years (seven years for automotive or high-reliability products).
    2. The product can be manufactured and has been in production for less than 10 years.
    3. The product has any current customer demand.

    Conditions 1 and 3 above hold true for my company which leads to the question of why is this commercial family being discontinued?

    HI Chris,

    I have forwarded your query regarding device availability of the TLE2426, TLE2426-Q1 and EOL questions to the Product Engineers, as I don't have immediate access to additional information on device availability beyond the information posted on www.ti.com.  Please allow 24 hours.

    Thank you and Regards,

    Luis

    Thank you Luis.  It is also interesting to note, PDN20230907001.3 suggests replacement for TLE2426CDG4 is TLE2426CDR.  However, TLE2426CDR is also in LTB status.

    Hi Chris,

    I was informed yesterday that the complete family of TLE2426 including the TLE2426DRG4-Q1 automotive grade device, will be placed in Last Time Buy status in the following weeks. Since I am part of the Application's team focused in technical support, we don't have visibility on device availability or EOL status beyond information publicly available on www.ti.com. I will wait for the Product team to reach out to you directly with details.  

    The devices still can be purchased while they remain available on LTB status.  Beyond this, a long term a solution is to implement a similar discrete solution with an op-amp.  

    Thank you,

    Best Regards,

    Luis

    Hi Chris,

    Sorry for the confusion.  PCN number 20230907001 incorrectly lists the TLE2426CDR as a replacement TLE2426CDG4; the entire family will be EOL, including the automotive version.  The reason for EOL is that it is that this very old device is no longer manufacturable.

    We will send a new PCN within the next few weeks that will notify customers about the automotive grade EOL status, at which point it will be published to the web.  Note that devices will still be able to order in the next 12 months.

    Regards,
    Mike

    If you care about accuracy, then the simplest way to get precision resistors is to use any difference amplifier with G=1:

    Hi Chris,

    It seems that you point to the typo in the following phrase: "TI standard products are not eligible for obsolescence if any of these three conditions exist:"  The statement should actually read: "TI standard products are not eligible for obsolescence if ALL of these three conditions exist:"

    Since the very old process mentioned in (2) used to manufactured TLE2426 cannot be maintained anymore due to its age, all products using it will be discontinued.

    Hi Marek,

    Just to confirm, the TLE2426 family is being discontinued despite the EOL Policy on the website per the Product life cycle page claiming exactly what Chris said earlier in which it states "if any of these three conditions exist" (screenshot from that page also below)? I understand that the manufacturing process is old and we're trying to move everything to new fabs, but if what's listed on the actual website doesn't state what you said about "all of these three conditions" then what is the real truth here? Is there truly just that bad of a typo on our end? It seems like this device is used widely across a lot of products from Chris's team, so clarification and proper justification would be great. Obviously, this would hurt their design cycle if a replacement part has to get designed in.

    Hi Marco, Chris,

    Regarding the question about the phrasing in the policy, we'll align with the quality team.  Generally, the scope of e2e is to cover any technical support problems, not questions related to product lifetimes, so I will contact you (Marco) directly for updates on this topic.

    Regards,
    Mike
