Question

Is there a cross reference for SMD component markings?

Answer

Usually each component datasheet contains the various ID codes for the different grades and packages of a particular device. This is only useful if you already know the manufacturer and base part number. Some manufacturers also have a cross reference online.

For a generic reference try the SMT marking codes page at Robs Electronics Site. You could also try SMD Code Tabelle and SMD Halbleiter
