Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Output Type: Must support Commutation output
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The AMT313Q-V meets all mandatory substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 400 PPR of the AMT303LD-V, it maintains compatibility across all mechanical, electrical, and environmental parameters required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and environmental compliance certifications.

The AMT313Q-V carries Active product status, ensuring ongoing availability and support. Both parts maintain RoHS compliance and REACH unaffected status, meeting current regulatory requirements. The AMT313Q-V achieves ROHS3 compliance, representing current industry standards.

The primary functional difference is the programmable pulses per revolution capability of the AMT313Q-V, which can be configured to match the 400 PPR specification of the original part through programming, while maintaining all other electrical and mechanical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modification?

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V across all mounting, orientation, supply voltage, and termination parameters. The programmable PPR feature of the AMT313Q-V can be configured to 400 PPR to match the original specification.

Q: What is the difference between fixed 400 PPR and programmable PPR?

A: The AMT303LD-V provides a fixed 400 pulses per revolution output. The AMT313Q-V allows PPR configuration through programming, enabling the same 400 PPR output or alternative values depending on application requirements.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V uses terminal pin termination. The AMT313Q-V also uses terminal pin termination, maintaining identical packaging compatibility.

Q: What is the compliance status of the substitute part?

A: The AMT313Q-V meets ROHS3 compliance and maintains REACH unaffected status, satisfying current regulatory requirements for electronic components.

Q: Why is the original part obsolete?

A: The AMT303LD-V is classified as obsolete by the manufacturer. The AMT313Q-V represents the current active alternative within the CUI Devices AMT encoder product line.
