Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V is identified as a substitute for the AMT303LD-V based on the following alignment of critical parameters:

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center actuators
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configurations
• Termination Style: Both use terminal pins
• Output Type: Both provide commutation output
• Compliance: Both are RoHS compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 250 PPR. The AMT313Q-V is classified as active product status, making it a viable alternative for applications requiring the same mechanical and electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the obsolete AMT303LD-V in applications where the following conditions are met:

• The system can accommodate programmable pulse-per-revolution configuration, or the application can be configured to operate at 250 PPR
• The mechanical interface (right-angle orientation, 2mm ~ 8mm open center actuator, terminal pin termination) matches the original installation
• The 5V supply voltage requirement is maintained
• The active product status of the AMT313Q-V ensures ongoing availability and support

Both components meet identical compliance requirements (RoHS, REACH, MSL 1) and share the same ECCN and HTSUS classifications, confirming regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares identical mechanical mounting, electrical supply voltage, and termination characteristics with the AMT303LD-V. However, the programmable PPR feature of the AMT313Q-V requires configuration to match the fixed 250 PPR specification of the original part. Physical installation compatibility is confirmed.

Q: What is the significance of the programmable PPR feature in the AMT313Q-V?

A: The AMT313Q-V allows pulse-per-revolution configuration, providing flexibility for different resolution requirements. For direct substitution, this parameter must be set to 250 PPR to match the AMT303LD-V output characteristics.

Q: Are there compliance differences between these two parts?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 compliance, which represents a more recent standard iteration. Both share identical ECCN (EAR99) and HTSUS (8543.70.4500) classifications.

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

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

Q: Are the packaging formats compatible?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination, ensuring compatibility with existing connector and installation infrastructure.
