Other Parts Discussed in Thread: OPA2990, LF411, SN54LS26, LM111, LM111JAN, LM101AJAN

Hi Team,

My customer would like to know if we could provide an alternative product for the device below.

1) M38510/10103BCX

2) M38510/10304BGX

3.) 4BTF2

Can you also add other information about these devices ( either discontinued, obsolete, etc.) I tried to search for information unfortunately, I couldn't find anything.

Regards,

-Renan

    Hi Renan,

    Can you help provide a little more information on the application and which specs are most important to the customer? The first two devices appear to be variants of the LF411 which is still for sale, but maybe a newer amp will meet their needs better, like the OPA2990.

    I am unclear what type of part the third one is, can you clarify? A google search makes it seem like it might be a switch.

    Thanks,
    Paul

    Hi Paul,

    My customer only gives this information from their logisticians' records:

    1.) M38510/10103BCX is listed as a microcircuit; OEM is TELEDYNE E2V (UK) LTD with an MPN of M38510/10103BCX. With a note stating: Part is available from Texas Instruments: www.ti.com/.../samplebuy
    - Unfortunately, I can't find any information that M38510/10103BCX is an obsolete part number of SN54LS26 or any devices.

    2.) M38510/10304BGX is listed as a microcircuit; also from TELEDYNE, Generic PN is LM111. With a note stating: Part is available from Texas Instruments: www.ti.com/.../samplebuy.
    - Unfortunately, I can't find any information that M38510/10304BGX is an obsolete part number of LM111JAN or any devices.

    3.) listed as a thermostatic switch with the following note: CPN: 4BTF2-CLOSE

    I hope this helps.

    Regards,
    -Renan

    Renan,

    You can try the TI M38510 versions of SN54LS26 and LM111. TI does not sell thermostatic switches.
    I'll transfer ownership of this thread to high reliability group. They understand the M38510 devices better.

    Thanks Ron.

    Sorry for delay.  I replied to this yesterday, but for some reason it did not take.

    I searched the DLA website, and neither the 10103, nor the 10304 device types have specifications.

    I suspect they are the wrong part numbers. 

    The military versions of the SN54LS26 or LM111 can be evaluated for suitability.  However, without a base specification to compare to that may be very difficult.

    If you can locate specifications to cross with, we can help evaluate if they are suitable replacements.

    Regards,

    Wade

    Renan,

    I looked at this again.  The drawing is on the DLA website, but since it is a combined drawing, the actual drawing name is 101K

    1) M38510/10103BCX  

     Shows to be inactive for designs after 1995.

    This is LM101A

    2) M38510/10304BGX

    Similarly, but harder to find, the DLA drawing is

    This appears to be a comparator LM111.

    The responsible engineer for these devices is currently out of the office.  They can evaluate and provide recommendation for replacement device.

    Regards,

    Wade

    Hello Renan,

    I believe that the first two products are available and orderable (I just think that the part numbers are slightly off and not actual part numbers).

    Instead of M38510/10103BCX, i think it is M38510/10103BCx where the small x is a wildcard for the lead finish and is not a real part number.  The last character is lead finish and there is no X lead finish.  The X probably indicates they will take any lead finish.

    We still offer this part.  The part number is M38510/10103BCA where A is for SnPb solder dip.  This is a mil grade LM101 in a CDIP and can be found in the product page LM101AJAN

    Ths other part you want is the M38510/10304BGA which is the mil grade LM111 in a metal can with SnPb solder dip.

    I do not know what 4BTF2 is and would need more information.
