Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute based on the following matching parameters:

• Incremental encoder type
• 5V supply voltage
• 2mm ~ 8mm open center actuator type
• Chassis mount and motor mounting capability
• Right-angle orientation
• Terminal pin termination
• RoHS compliance (ROHS3 Compliant)
• REACH unaffected status
• EAR99 ECCN classification

The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 512 PPR. The AMT313Q-V carries active product status, making it suitable for applications requiring long-term component availability.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Selection should be based on the following criteria:

Product Status Consideration: The AMT303LD-V is obsolete, while the AMT313Q-V maintains active product status. For new designs or long-term production requirements, the AMT313Q-V provides assured component availability.

Compliance Alignment: Both parts maintain equivalent regulatory compliance. The AMT313Q-V achieves ROHS3 compliance, representing current RoHS standards. Both parts carry REACH unaffected status and EAR99 ECCN classification, ensuring consistent regulatory positioning.

Functional Compatibility: Mechanical and electrical interfaces are compatible across both parts. The shared 5V supply voltage, identical actuator range, right-angle orientation, and terminal pin termination enable direct substitution in existing mechanical assemblies.

Resolution Consideration: The AMT303LD-V provides fixed 512 PPR output. The AMT313Q-V offers programmable resolution, allowing configuration to 512 PPR or alternative values as required by system design. This flexibility supports both direct replacement and future design optimization.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting interfaces (chassis mount, right-angle orientation, 2mm ~ 8mm open center actuator), electrical supply voltage (5V), and terminal pin termination. Physical and electrical integration is compatible.

Q: What is the primary difference between these two parts?

A: The AMT303LD-V provides fixed 512 PPR output. The AMT313Q-V features programmable pulses per revolution, allowing configuration to match the required resolution. Both maintain incremental encoder operation with commutation output.

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, offering equivalent functionality with extended availability.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V packaging is not specified in available data. The AMT313Q-V is supplied in box packaging. Confirm packaging requirements with your procurement specification.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts maintain RoHS compliance (AMT303LD-V: RoHS Compliant; AMT313Q-V: ROHS3 Compliant), REACH unaffected status, and EAR99 ECCN classification. Regulatory positioning is equivalent for industrial applications.

Q: What inventory status should I consider for procurement?

A: The AMT303LD-V shows 936 units in stock as new original inventory. The AMT313Q-V shows 1349 units in stock. For long-term production, the active status of the AMT313Q-V provides superior supply chain assurance compared to the obsolete AMT303LD-V.
