May claim compatibility but is not guaranteed to match exactly |
| Compatibility | Designed for specific Kobelco models (e.g., SK130, SK140) | Often a universal "will-fit" that may have incorrect connectors or pin-outs |
| Wire Quality | High-temp, thin-wall insulation; high-purity copper for optimal conductivity | Inferior insulation that can crack; lower conductivity leading to voltage drop |
| Connectors | OEM-specified, sealed connectors with corrosion-resistant terminals | Poor-quality connectors that are prone to corrosion and poor contact |
| Durability | Robust construction with OEM-style routing and protection in high-wear areas | Lacks proper conduit and chafe protection, leading to premature failure |
| Reliability | Fully tested for continuity and insulation; provides long-term, stable performance | High risk of internal faults, shorts, and intermittent failures from day one |
| Warranty & Support | Backed by a comprehensive warranty and technical support | Limited or no warranty, with little to no product support |
