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

The AMT313Q-V qualifies as a substitute part because it matches all mandatory mechanical and electrical parameters. The key difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 800 PPR. This programmability provides additional flexibility for system integration while maintaining full compatibility with the physical and electrical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V. Both components share identical mechanical interfaces, electrical supply requirements, and regulatory compliance profiles. The AMT313Q-V maintains active product status with ROHS3 compliance, ensuring long-term availability and supply chain stability.

The primary functional difference is the programmable pulses per revolution capability of the AMT313Q-V, which can be configured to 800 PPR to match the original specification. This programmability does not compromise compatibility and provides additional design flexibility for future applications.

Both parts carry identical REACH and ECCN classifications, confirming equivalent regulatory standing for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting, electrical interface, and supply voltage specifications. The AMT313Q-V can be configured to 800 PPR to match the original part's output resolution.

Q: What is the primary advantage of the AMT313Q-V over the AMT303LD-V?

A: The AMT313Q-V features programmable pulses per revolution, allowing configuration flexibility without requiring different part numbers for different resolution requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are REACH Unaffected and classified as EAR99. The AMT313Q-V carries ROHS3 compliance compared to the AMT303LD-V's RoHS compliance. Both meet current regulatory requirements.

Q: Does the packaging differ between these parts?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in a Box. This does not affect component functionality or interface compatibility.

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

A: Obsolete status indicates the part is no longer in active production. The AMT313Q-V represents the current active alternative from CUI Devices for this encoder category.

Q: Are the terminal pin configurations identical?

A: Both parts use terminal pin termination style and are designed for identical mounting applications (Chassis Mount, Motors). Pin configuration compatibility is maintained.
