Substitution Feasibility Conclusion
Direct substitution of model MURD4002GVNBCA00ABA0 for model MMRD4002GVNBCA00ABA0 is not feasible due to physical dimension and interface incompatibility. If an adapter is employed while maintaining the same communication protocol, equivalent storage performance can be achieved. However, the mechanical reliability of the adapter and limitations in the application scenario must be evaluated.
Comparison Points
1. Physical dimensions and connector type: MMRD4002GVNBCA00ABA0 is an SD™ card (standard size), whereas MURD4002GVNBCA00ABA0 is a microSD™ card (miniature size). The two are not plug‑and‑play compatible in hardware design. Substitution requires either an adapter or a redesign of the card slot, which may introduce connection reliability risks or increase cost.
2. Series designation: The MMRD4 series corresponds to the SD card product line, while the MURD4 series corresponds to the microSD card product line, reflecting different packaging standards and target applications. For example, SD cards are commonly used in devices with standard interfaces such as cameras and industrial equipment, whereas microSD cards are better suited for mobile devices or space‑constrained embedded systems. Substitution must account for mechanical and electrical compatibility within the intended application environment.
