Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical supply voltage (5V), mounting type (Chassis Mount, Motors), orientation (Right Angle), actuator type (2mm ~ 8mm Open Center), and termination style (Terminal Pins). The commutation output interface is compatible between both parts.

Q: What is the key difference between the AMT303LD-V and AMT313Q-V?

A: The primary difference is pulses per revolution configuration. The AMT303LD-V provides fixed 192 PPR output, while the AMT313Q-V features programmable PPR capability. The AMT313Q-V can be configured to operate at 192 PPR to match the original specification.

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

A: The AMT303LD-V is no longer in active production. The AMT313Q-V represents the current active product line from CUI Devices for this encoder category.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with dash packaging, while the AMT313Q-V is supplied in box packaging. Both maintain identical electrical and mechanical specifications.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both components are RoHS compliant and REACH Unaffected. The AMT313Q-V achieves ROHS3 compliance, representing the latest regulatory standard.

Q: What is the moisture sensitivity level for both encoders?

A: Both the AMT303LD-V and AMT313Q-V are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
