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: Both are incremental encoders
• Voltage Supply: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center design
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configuration
• Termination Style: Both use terminal pins
• RoHS Compliance: Both meet RoHS standards
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)

Distinguishing Parameter:

• Pulses per Revolution: AMT303LD-V provides fixed 200 PPR; AMT313Q-V offers programmable PPR capability
• Output Type: AMT303LD-V specifies commutation with line driver; AMT313Q-V provides commutation output
• Product Status: AMT303LD-V is obsolete; AMT313Q-V is active

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V serves as an active substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply voltage, and environmental compliance ratings. The AMT313Q-V maintains active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment.

The primary technical distinction is the programmable pulses per revolution capability of the AMT313Q-V, which provides operational flexibility compared to the fixed 200 PPR specification of the AMT303LD-V. Applications requiring the fixed 200 PPR output specification must evaluate whether the programmable alternative can be configured to meet system requirements.

Frequently Asked Questions (FAQ)

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

A: Both components share identical mounting type, orientation, actuator type, supply voltage, and termination style. The AMT313Q-V can be mechanically and electrically integrated into applications designed for the AMT303LD-V. The programmable PPR feature of the AMT313Q-V must be configured to match the 200 PPR requirement if the original design depends on this fixed specification.

Q: What are the compliance differences between these parts?

A: The AMT303LD-V carries RoHS Compliant certification. The AMT313Q-V carries ROHS3 Compliant certification, representing a more current regulatory standard. Both components are REACH Unaffected and carry EAR99 ECCN classification.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with dash packaging. The AMT313Q-V is supplied in box packaging. Both use terminal pin termination suitable for standard assembly processes.

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

A: The AMT303LD-V has reached end-of-life status. The AMT313Q-V represents the active product line continuation from CUI Devices for incremental rotary encoders in this category, offering programmable configuration flexibility while maintaining mechanical and electrical compatibility.
