A scrollable page of data will appear in the main frame. Unfortunately, each device code is not necessarily unique. For example a device coded 1A might be either a BC846A or a FMMT3904. If there is more than one entry, use the package style to differentiate between devices with the same ID code. This compilation has been collected from manufacturers' data and other sources of SMD device ID codes, pinout and leaded device equivalent information.
Many manufacturers use an extra letter as their own identification code.
This has been a problem in the past, howver recently manufacturers have been adding lower case letters which clarifys the code - the codebook is being updated to reflect this. Many recent Motorola devices have a small superscript letter after the device code, such as SA C . This smaller letter is merely a month of manufacture code. Many devices from Rohm Semiconductors which start with G have direct equivalents found in the rest of the number. For example GD1 is the same as D1 which is a BCW31.
