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:

Matching Parameters:

• Encoder Type: Incremental
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• RoHS Status: Compliant (ROHS3)
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Key Difference:

• Pulses per Revolution: AMT303LD-V provides fixed 1024 PPR, while AMT313Q-V offers programmable PPR capability
• Output Type: AMT303LD-V specifies commutation with line driver; AMT313Q-V specifies commutation output
• Product Status: AMT303LD-V is obsolete; AMT313Q-V is active

The substitution is valid when the application can accommodate programmable pulse resolution and does not require the specific line driver configuration of the original part.

Parameter Comparison

Engineering Selection Recommendations

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

1. Programmable Resolution Compatibility: The application must support or benefit from programmable pulse-per-revolution configuration. The AMT313Q-V can be configured to 1024 PPR to match the original specification.

2. Active Product Status: The AMT313Q-V maintains active product status with CUI Devices, ensuring continued availability and support compared to the obsolete AMT303LD-V.

3. Regulatory Compliance: Both parts meet RoHS and REACH requirements. The AMT313Q-V carries ROHS3 compliance, representing current regulatory standards.

4. Mechanical and Electrical Compatibility: Identical mounting, orientation, actuator type, supply voltage, and termination style ensure direct mechanical and electrical compatibility in chassis mount and motor applications.

5. Output Configuration Consideration: Applications requiring the specific line driver output of the AMT303LD-V must evaluate whether the AMT313Q-V commutation output meets system requirements.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares identical mechanical mounting, orientation, actuator type, supply voltage, and termination style. However, the output type differs: the original part includes line driver capability, while the substitute provides commutation output. System compatibility depends on whether the application can operate with the substitute output configuration.

Q: What is the primary advantage of the AMT313Q-V over the AMT303LD-V?

A: The AMT313Q-V offers programmable pulse-per-revolution resolution, providing design flexibility. Additionally, it maintains active product status, ensuring long-term availability and support.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS and REACH compliant. The AMT313Q-V carries ROHS3 certification, representing the current regulatory standard, while the AMT303LD-V carries RoHS Compliant status. Both maintain MSL 1 (Unlimited) rating.
