Is there any suitable replacement for the Epson RTC63421A? I've found them on eBay before but they turned out to be fakes even though I bought them from LittleDiode. I see utsource offer them and in necessary I'll order ten of them and take the USD30 shipment hit so long as I can be sure about them.
However before doing that - does anyone know of a pin compatible replacement? ISTR there used to be a "Master XREF" that seems long gone.
