Part Numbers

Sun part numbers consist of nine numerical digits separated with dashes (-) into three components; Class Code, Base Number, and Dash Number. A revision number or letter is used with each part number.

Class Codes identify similar parts.

Base Numbers are assigned sequentially. A higher base number does not necessarily indicate a new or improved part.

Dash Numbers are used to identify changes made to the part that affect form, fit, or function.

Revision Numbers are used to identify changes made to the part that do not affect form, fit, or function. Revisions 00 to 49 indicate that a part is not engineering released. Revisions 50 to 99 indicate that a part is engineering released. Revisions A to Z indicate that a part is production released.
