vaihdettava

Vaihdettava is a Finnish adjective meaning "exchangeable" or "replaceable." It describes something that can be swapped for another item or substituted without compromising the function or integrity of a system. The term is commonly used in technical, manufacturing, and consumer contexts to indicate compatibility, modularity, or the possibility of maintenance replacements.

The form is created with the -ettava suffix from the verb vaihdata/vaihtaa, meaning to exchange or swap. It is used both attributively and predicatively: for example, "vaihdettava osa" (an interchangeable part) or "Osa on vaihdettava" (the part must be replaced). In technical and contractual language, vaihdettava emphasizes that a component can be substituted during service or under warranty.

Common usages include "vaihdettava akku" (replaceable battery), "vaihdettavat suodattimet" (replaceable filters), and "vaihdettavat osat" in manuals and product specifications. The term often signals modular design, where components are designed to be swapped without specialized tools or downtime.

A related noun is vaihdettavuus, meaning replaceability or interchangeability. The word has English equivalents such as exchangeable, replaceable, or interchangeable, depending on context.

Etymology: Vaihdettava derives from vaihto ("exchange") plus the suffix -ettava, a Finnish derivational ending that marks capability or suitability.
