Part Number: SE555M
I am interested in the SE555M device but the product page only gives the generic xx555 datasheet so I cannot ascertain the differences between the product options below other than the fact that the _FKB part has a different package.
Does anyone have a reference that would have me ascertain the (presumably standard adherence) differences between the following sub-models of the SE555M
I am researching the differences and will get back to you tomorrow.

In reply to Ron Michallick:
I have at least half of the information gathered, but am I waiting on clarification on a couple points. Please be patient as this may take one more day.
In the meantime, what requirements are needed for your application?
Thanks for looking into this for me.
I am looking for a high reliability, extended temperature range 555 timer, some documented radiation tolerance would be nice but is not essential.
I have found a number of the sub-models of the SE555M available at varying prices so am wanting to understand which one might be most suitable for my application.
In reply to David Wright33:
JM38510/10901BPA & M38510/10901BPA are the same part, the J is a legacy markerM38510 is a military grade.
SE555FKB & SE555JGB also are military grade (note the B suffix)
SE555JG is just a ceramic wide temperature device. This is why it is less expensive.
See the SE555-SP for radiation tolerance. Part number 5962-9855501VPA
That is good information!
What are the differences between the M38510 and the SE555xxB devices? Are they adhering to different military standards? Is there a datasheet available there?
I am trying to get a quote for the SE555-SP device but I'm not having too much success on that front...
Start here; https://www.ti.com/support-quality/faqs/automotive-hirel-faqs.html
Near bottom of the page is this: military and HiRel products process flows. In it, among other things, you will see that "B" is MIL-PRF-38535 (QML)
Only SE555 has a dedicated data sheet, the other share the commercial data sheet.
For non technical questions such as purchasing. Try the advice in the last post (Feb 13) of this thread. https://e2e.ti.com/support/amplifiers/f/14/p/878948/3254018#3254018
Thank you very much for that information. As a final clarification/confirmation M38510/10901BPA and SE555JGB are identical? both being the same device that is compliant with MIL-PRF-38535.
As these parts are not radiation tolerant. Can you confirm that they would therefore be considered QML Class Q?
M38510/10901BPA and SE555JGB are built in the same way. The differences are in electrical test. (slide page 11)M38510/10901BPA is tested by JAN slash sheet requirements.SE555JGB is tested by current TI Data sheet.
Yes, QML Class Q
