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
• 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 500 PPR. The AMT313Q-V is currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical mechanical and electrical interface specifications, including supply voltage, actuator dimensions, mounting configuration, and termination method.

The AMT313Q-V maintains active production status and meets current RoHS3 compliance requirements, providing long-term availability and regulatory alignment. The programmable pulses per revolution feature of the AMT313Q-V offers design flexibility while maintaining backward compatibility with systems designed for 500 PPR operation.

Both components carry equivalent environmental ratings (MSL 1, REACH unaffected) and are suitable for direct substitution in chassis mount and motor-driven applications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting, electrical supply requirements (5V), actuator specifications (2mm ~ 8mm open center), and termination style (terminal pins). The AMT313Q-V can be configured to operate at 500 PPR to match the original specification.

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

A: The AMT303LD-V has a fixed 500 PPR output, while the AMT313Q-V features programmable pulses per revolution. Both maintain identical physical form factors and electrical interfaces.

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

A: The AMT303LD-V is no longer in active production. The AMT313Q-V represents the current active alternative from CUI Devices for this encoder category.

Q: Are there any compliance differences between these parts?

A: Both components are RoHS compliant and REACH unaffected. The AMT313Q-V meets ROHS3 compliance, representing the current regulatory standard.

Q: What packaging is available for the AMT313Q-V?

A: The AMT313Q-V is supplied in box packaging.

Q: Are the moisture sensitivity ratings identical?

A: Yes. Both the AMT303LD-V and AMT313Q-V are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
