An ' L ' suffix usually indicates a low-profile package, such as an SOT323 or SC70 . Reverse joggle devices do present a few problems. They oftern have an ' R ' in the type number. A reverse package is one where the lead have been bent up instead of down. So it's a mirror image of a conventional device.
Identification is usually possible from the code number, but some manufacturers use the same code.
In these cases, it's a case of looking at the device with a magnifying glass. Sometimes similarities are also found in the code numbers. Recently some manufacturers have used a symbol or lower case letter to indicate the country of manufacture. These have been ignored in the alphabetical ordering. If the leaded device is well-known then no more information is given.
