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
• Environmental Compliance: Both are RoHS compliant and REACH unaffected
• Moisture Sensitivity: Both rated at MSL 1 (Unlimited)

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 512 PPR. The AMT313Q-V also carries an active product status, making it a viable long-term alternative.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Selection of the AMT313Q-V is supported by:

• Product Status: The AMT313Q-V maintains active product status, ensuring continued manufacturing and supply chain availability, whereas the AMT303LD-V is obsolete.
• Compliance Alignment: Both parts meet RoHS and REACH requirements. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards.
• Functional Compatibility: Matching supply voltage, mounting configuration, orientation, and termination style enable direct substitution in existing mechanical and electrical interfaces.
• Programmable Resolution: The AMT313Q-V offers programmable pulses per revolution, providing flexibility to configure 512 PPR operation or alternative resolutions as system requirements evolve.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical supply voltage (5V), actuator type (2mm ~ 8mm open center), mounting configuration (chassis mount, motors), orientation (right angle), and termination style (terminal pins). The AMT313Q-V can be configured to operate at 512 PPR to match the original specification.

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

A: The AMT303LD-V has a fixed 512 PPR output, while the AMT313Q-V features programmable pulses per revolution. This allows the AMT313Q-V to be configured for 512 PPR or alternative resolutions depending on application requirements.

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

A: The AMT303LD-V has reached end-of-life status. The AMT313Q-V represents the current active product offering from CUI Devices for this encoder category.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with terminal pin termination. The AMT313Q-V is packaged in a box configuration. Both use identical terminal pin termination style for electrical connection.

Q: Do both encoders meet current environmental compliance standards?

A: Yes. Both the AMT303LD-V and AMT313Q-V are RoHS compliant and REACH unaffected. The AMT313Q-V additionally meets ROHS3 compliance, reflecting current regulatory requirements.

Q: What is the moisture sensitivity rating for these encoders?

A: Both encoders are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
