why do you need an alternate? digi-key has that part for 1.33 in single quantity.

We are using this IC in Traffic Signal in the Toll application. The requirement and availability doesnt match hence we are looking for an alternate which would be easily available.

we cannot change the PCB, so i guess pin compatability is must. I dotn have any idea on wht the Ic does in the circuit.

the LNK306PN is a SOLE SOURCE offline switcher IC - https://www.electro-tech-online.com/custompdfs/2010/09/lnk302_304-306.pdf

you may find suppliers but there is no pin compatible chip.

the requirements should be fine but as to repair availability, you should have specified that when you contracted the design.

How many of these do you need? i believe that several others in the linkswitcher TN family are pin compatible with that part.
