@JRDMcLAREN are you still getting TLE8888 anywhere or do you just have a lot remaining?

I have last 5 pcs. I'm bought "last" 18 pcs in January 2022 from Digikey ..and have last 3 pcs F407VGT6 ....

JRDMcLAREN avatar Aug 09 '22 16:08 JRDMcLAREN

I see :( F407VGT6 is easy to get "used"

used TLE8888 are about $100 as part of Russian ECU the only ECU i know to use TLE8888

THX, 5pcs ordered .. and what kind of MCU can be used in near future ... F427VGT7 .. maybe .. Screenshot_20221212_195508

427vg is already used by MRE

TLE8888QKXUMA1 is marked as "End Of Life" on Mouser Screenshot_20230119_225958

it's a bit more complicated - primary version is active

@JRDMcLAREN please clarify what are you saying.

@JRDMcLAREN are you saying that mouser info is more reliable than https://www.infineon.com/cms/en/product/power/automotive-conventional-powertrain-ics/engine-management-ic/tle8888qk/ official status which shows "active" for me today?

My experience is, when Mouser has some product marked as EoL, then it is END OF LIFE. ..we need to make "new MRE" with any other chip, maybe ....

YES, Infineon says ACTIVE, but datasheet date is 05/2017, Product Brief is 08/2015 and Footprint is 02/2019

..just try to think about it...

(I have last 10pcs on stock)

when Mouser has some product marked as EoL, then it is END OF LIFE.

I fully agree with this statement. This would mean the end for producing new MRE boards with current design & components. What options for replacing TLE8888 do we have?

I've just ordered enough chips that I can worry about it all later

Let's move this to https://rusefi.com/forum/ where that amazing chip is already discussed in detail
