PARTS — Package And Reference Tagging System

PARTS is a Python-based labelling engine for electronic components. It generates clean, consistent PDF labels with accurate electrical symbols, simplified-style package drawings and key specifications, suitable for electronics labs, workshops and makerspaces.

PARTS is designed for engineers who care about correctness, repeatability and long-term component organisation.

Originally based on Finomnis/ResistorLabels, PARTS has evolved into a general-purpose component labelling system covering discrete passives, diodes, transistors and power devices.

Why PARTS?

Most label tools only print text.

PARTS prints meaning:

• Electrical symbols that match the device type
• Physical package drawings that match the real component
• Key electrical limits at a glance
• Consistent formatting across your entire lab

If you have ever pulled a part from a drawer and wondered “what exactly is this?”, PARTS is for you.
