1. Operating Temperature Range - Wintec model: 0°C to 70°C (commercial grade) - ATP model: -40°C to 85°C (industrial grade) - The ATP model is suitable for harsher environments (e.g., industrial, automotive, outdoor) due to its higher-grade component selection and process reliability. The Wintec model is only appropriate for mild commercial conditions. If the original application involves wide temperature ranges or thermal cycling, the ATP model can directly cover these requirements and improve system environmental robustness. 2. Speed Class Rating - The ATP model is clearly marked as Class 6 (minimum write speed 6 MB/s), while the Wintec model does not specify a class. - Class 6 provides a guaranteed minimum write speed per SD standards. The ATP model offers quantifiable continuous write performance, making it suitable for applications with explicit data write stability requirements, such as data logging. Although the Wintec model lacks a class rating, its SLC technology typically delivers higher random read/write performance—actual speeds should be validated through testing. For applications relying on sustained high-speed writes, the ATP model provides more reliable standardized assurance. 3. Implied Reliability Differences - Industrial-grade temperature design is generally accompanied by more rigorous lifetime testing (e.g., program/erase cycles, data retention) and enhanced interference resistance. - The ATP model likely offers superior long-term reliability and data integrity compared to commercial-grade products, especially in high-vibration, high-humidity, or continuous-operation scenarios. Substituting with the ATP model may potentially increase system MTBF (Mean Time Between Failures).
