Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical mechanical and electrical interface specifications, including supply voltage, mounting configuration, actuator compatibility, and termination style.

The AMT313Q-V offers the advantage of active product status, ensuring ongoing availability and manufacturing support. The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility beyond the fixed 1000 PPR specification of the AMT303LD-V, allowing configuration to match system requirements.

Both parts maintain equivalent RoHS compliance and REACH status. The AMT313Q-V meets ROHS3 standards, representing current regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V in existing designs?

A: Yes. Both encoders share identical mechanical mounting, electrical supply voltage, actuator type, and termination specifications. The physical and electrical interfaces are compatible.

Q: What is the significance of the programmable pulses per revolution in the AMT313Q-V?

A: The AMT313Q-V allows configuration of pulse output to match system requirements, whereas the AMT303LD-V is fixed at 1000 PPR. If your application requires exactly 1000 PPR, the AMT313Q-V can be programmed to this specification.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied in standard packaging, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination suitable for chassis mount applications.

Q: Why is the AMT303LD-V listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation. The AMT313Q-V represents the current active alternative within the CUI Devices encoder portfolio.

Q: Do both parts meet current compliance standards?

A: Yes. Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V additionally meets ROHS3 standards, representing the latest regulatory requirements.
