Part Number: LM1558QML

I need to know if LM1558H/883 is still available and how closely it aligns with M38510/10108BGX

    Hi Steve,

    Please find the specs below for LM1558H/883:

    I believe " M38510/10108BGX" is an orderable part number. Can you please share the generic part number? I couldn't find the datasheet for this device to provide you a comparison. If you've a link to this datasheet, please share it with us.

    Best Regards,

    I know that LM1553H is widely available but I need to know the availability of LM1553H/883.   Will likely have a lead time and min buy requirement.

    I have no doubt that TI could build M38510/10108BGX but I do not believe that it is an active part number.

    It is defined by MIL-M-38510 slash sheet 101.

    When I compare the LM1558QML data sheet to MIL-M-38510 slash sheet 101 - I believe that the M38510/10108BGX is tested to a tighter tolerance during the MIL-STD-883 Group A tests.

    Hi Steve,

    Did you mean to type LM1558H? I believe you're correct, we're out of stock on ti.com. You can still buy them from our distributors but I'm not sure on the lead time and min buy requirements. I will loop in with our marketing team and try to get you more information on purchase options. 

    In regards to M38510/10108BGX, I don't think this is an active device because I couldn't find the datasheet no matter how much I searched on ti.com. I will do more research on this and get back to you tomorrow. 

    Do you've any specific requirements in choosing an op amp such as offset voltage, bandwidth, slew rate etc... ? 

    Best Regards,

    Yes - sorry for the typo - the part is indeed LM11558H/883

    Your website lists it as an active part - but I need to know:

    What are factory lead times and min buys ?

    Is there a forecasted End-of-Life decision ?

    Thanks !

    HI Steve,

    No worries. I think you meant to type LM1558H/883. So, I heard back from one of my colleagues that's an expert in these parts. Looks like M38510/101 is obsolete but the drop in mil-grade replacement for this part will be LM1558H/883. This device is active on ti.com. There might be some slight differences in parameters tested or limits, so please compare this datasheet with M38510/101 slash sheet to make sure there aren't any critical differences. LM1558H/883 gets all the processing, testing and qualification as that of a mil grade product as per MIL-PRF-38535, which superseded MIL-I-38510 which governs the slash sheet parts. 

    I don't believe there is any EOL (end of life) decisions for this device. I've reached out to the marketing team to check on lead time and MOQ (minimum orderable quantity), I will follow up with you once I've an answer. 

    Best Regards,

    Bala Ravi

    Hi Steve, 

    I heard back from our marketing folks. We could support 20 units with 2 weeks lead time for this device. Please let us know if we can further assist you.

    Bala,

    Thank you very much for the information - one minor clarification and then I can be "resolved"

    Can you tell me what your EOL horizon is - that is to say if a part is "Active" at some vendors then 

    that means they have no plans within 3 years for last time buys but some vendors have a 5 year

    horizon that they plan out to.    I just need to estimate life for my product support analysis.

    Regards,

    Steve

    Hi Steve, 

    This device is currently "Active" on ti.com. We are committed to product longevity for our customers and have strategies and internal policies in place to uphold this commitment. We make an effort not to obsolete TI standard products out of convenience, and we have procedures in place to ensure that we can stand by this. We have established clear guidelines to ensure that we only consider a TI standard product for obsolescence when three conditions simultaneously exist: the product has had no sales for the last five years (seven years for automotive or high-reliability products), it has been in production for at least 10 years, and there is no current customer demand. LM1558H/833 has steady business and sells thousands of units each year, so we have no immediate plans to EOL this device.

    For more details regarding TI’s product longevity, please see the following link: http://www.ti.com/support-quality/quality-policies-procedures/product-life-cycle.html

    Best Regards,
