Will an alternative ic work

[Njackste]

I need to replace an ltc4054 but my local Farnell/rs don't have it but they have alternatives such as this https://ie.rs-online.com/web/p/battery-management/7328730.

Will this work?

Will any other alternatives that I can get locally work.

Otherwise I'll just get it on AliExpress or eBay

The Maxim part provides a similar function but it is not pin compatible.

Thank you

Many other mfgrs copy ICs and they still retain the core part number...in this case "4054"....so a quick search for "4054 battery management"...finds quite a few with the same foot print.

Looking at LTC4045 datasheet Vs STC4054..only a quick glance...looks pretty good to me as a drop in alternate.   There are others as well....LR4054.   Of course I reserve the right to be completely wrong here!
