部 (section) + 件 (item) = a part or component. Each section-item is one piece that slots into a larger whole, like a bolt in an engine.
部 — 阝(邑) right + 咅 phonetic
The right-side 阝 derives from 邑 (city/settlement), giving the meaning of a region, district, or administrative division. The left side 咅 supplies the sound. Originally referring to a settlement, the meaning broadened to 'part,' 'section,' or 'ministry.'
件 — person radical 亻 + ox 牛
件 combines the person radical 亻 with 牛 (ox). Originally it referred to dividing or counting items, with oxen being valuable units of property to count. It came to mean a measurable item or matter, and today serves as a measure word for things, documents, and affairs.
