Understanding Component Replaceability
What It Measures
Component Replaceability evaluates how easily worn or failed individual parts can be swapped out without replacing the entire product. This includes batteries, filters, seals, blades, handles, and other consumable components.
Why It Matters for BIFL
A product is only as long-lived as its weakest component. Replaceable parts mean the product can outlive any single component failure — turning a 5-year product into a 20-year one.
How We Score
We evaluate part availability, standardization (proprietary vs. universal), replacement difficulty level, and cost of replacement parts relative to product price.
Historical Context
The EU's Ecodesign Directive (2019) introduced mandatory repairability requirements. Framework Laptop (2021) demonstrated that consumer electronics could embrace full modularity.
