Hi parthan,

Welcome to the Tech Forum!

It looks like the Texas Instruments TXS4555RGTR and the ON Semi FXLP4555MPX have the same pinout and at least very similar electrical characteristics. I would still check them carefully to ensure compatibility with your design, but they look promising.

As an aside, we still have a large number of NCN4555MNR2G available via out Marketplace vendor, Rochester Electronics, so that is also an option. As it is obsolete, if you go that route, I would suggest getting as many as you’ll need for the life of your product.

Thank you!
I will post how the subs worked out.
