Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center actuator
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configuration
• Termination Style: Both use terminal pins
• Output Type: Both provide commutation output
• RoHS Compliance: Both meet RoHS requirements
• Moisture Sensitivity Level: 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 800 PPR. The AMT313Q-V is classified as active product status, providing continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the AMT303LD-V based on the following factors:

• Product Status: The AMT313Q-V maintains active product status, ensuring ongoing manufacturer support and availability, whereas the AMT303LD-V is obsolete.
• Compliance Alignment: Both parts meet RoHS requirements and maintain identical MSL ratings, supporting equivalent environmental and regulatory compliance.
• Functional Compatibility: Matching supply voltage, mounting configuration, orientation, and termination style ensure mechanical and electrical compatibility within existing system designs.
• Enhanced Capability: The AMT313Q-V provides programmable pulse per revolution configuration, offering flexibility for applications requiring resolution adjustment without hardware replacement.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting the AMT303LD-V?

A: The critical parameters are encoder type (incremental), supply voltage (5V), actuator type (2mm ~ 8mm open center), mounting type (chassis mount, motors), orientation (right angle), termination style (terminal pins), and output type (commutation). The AMT313Q-V matches all these parameters.

Q: How does the programmable PPR feature of the AMT313Q-V affect substitution?

A: The AMT303LD-V is fixed at 800 PPR, while the AMT313Q-V offers programmable resolution. For direct substitution, the AMT313Q-V can be configured to 800 PPR to match the original specification. This provides equivalent functionality with added flexibility.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V packaging is listed as standard, while the AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination and mounting configurations, so packaging differences do not affect functional compatibility.

Q: What is the significance of the product status difference?

A: The AMT303LD-V is obsolete, meaning CUI Devices no longer manufactures or supports this model. The AMT313Q-V is active, ensuring continued availability, technical support, and compliance updates from the manufacturer.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 certification, representing the current RoHS standard, while the AMT303LD-V meets the original RoHS requirement. Both maintain MSL 1 (Unlimited) rating.
