I don't think the answer is that simple and may depend on your usage. For Tier 2 Conventional DMR operation, they *may* be compatible. Tier 3 trunking compatibility is a different matter. My understanding is that the Motorola Capacity Plus and Capacity MAX MOTOTRBO trunking systems are
not compatible with other vendor's DMR Tier 3 trunking radios (such as the Tait TM9300). The exception is Capacity MAX systems running in DMR Tier III “Interoperability” mode. However this mode will disable some of the MOTOTRBO features.

DMR Tier III Compliant
The system supports all the innovative features you’d expect from MOTOTRBO, from advanced location tracking to long text messaging and enhanced security. For customers who need a system that supports other vendors’ radios, Capacity Max can be run in DMR Tier III “Interoperability” mode with these features disabled.""
