    Usually, a letter suffix represents a minor difference such as packaging type, pin configuration etc. To be sure, go to datasheetcatalog.com where you could download free IC datasheets in PDF format.

    ps, that's a VU meter. It was only a typing error, but it matters because it confuses people into wondering if you want to use ultraviolet (UV) LEDs or measure ultraviolet light intensity.
