What Counts as Compatibility Evidence?
The strongest compatibility evidence explicitly connects an exact product model to an exact replacement part in an authoritative source. Appearance, dimensions, keyword overlap, and marketplace titles can support research but cannot establish the relationship alone.
Use a clear source hierarchy
Manufacturer parts pages, manuals, and official support records are preferred for model-to-part relationships. Replacement-maker and retailer claims should stay attributed to the party making them.
| Evidence | Use |
|---|---|
| Manufacturer/manual | Primary model-to-part relationship |
| Replacement maker | Attributed aftermarket compatibility claim |
| Retailer/marketplace | Discovery and availability, not standalone proof |
| Visual similarity | Physical cross-check only |
Keep region and revision in scope
A source is useful only within the models, markets, dates, and revisions it actually covers. When sources conflict, Filter Fit preserves the conflict for review rather than selecting the most convenient claim.
Evidence and shopping are separate
A purchase link does not raise a compatibility claim’s confidence, and commission must not determine ranking or verification.

How this guide was prepared
Filter Fit separates compatibility evidence from purchase availability. Exact model identity, region, revision, and authoritative source scope are reviewed before a relationship is treated as verified.
