AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 512 pulses per revolution with 12-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback. The AMT303-V is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by the following critical parameters that must remain consistent across equivalent parts:

• Encoder Type: Incremental operation
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation configuration
• Termination Style: Physical connection method

The substitute parts AMT313Q-V and AMT313S-V maintain compatibility with these core parameters. Both substitutes feature programmable pulses per revolution, which provides functional equivalence to the fixed 512 PPR configuration of the AMT303-V when programmed to 512 PPR operation.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these substitutes is determined by termination requirements:

AMT313Q-V features terminal pin termination, matching the connection style of the original AMT303-V. This substitute is suitable for applications requiring direct pin-based circuit board integration.

AMT313S-V features connector termination, providing an alternative connection method for applications where modular or field-replaceable configurations are preferred.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The programmable pulses per revolution capability of both substitutes provides operational flexibility while maintaining 512 PPR functionality when configured accordingly.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V without modification?

A: Both substitutes maintain identical electrical specifications (5V supply, incremental encoder type, commutation output, right-angle orientation, and chassis mount configuration). The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination. Selection depends on your circuit board connection requirements.

Q: What is the significance of programmable pulses per revolution in the substitute parts?

A: The AMT303-V operates at a fixed 512 PPR configuration. The AMT313Q-V and AMT313S-V offer programmable PPR settings, allowing 512 PPR operation when configured accordingly. This provides equivalent functional performance with added flexibility for future applications.

Q: Are there compliance differences between the original and substitute parts?

A: The AMT303-V is RoHS Compliant. Both substitutes are ROHS3 Compliant, representing a more recent compliance standard. All three parts maintain REACH unaffected status and EAR99 export classification.

Q: Which substitute should be selected for new designs?

A: For new designs, either AMT313Q-V or AMT313S-V is appropriate based on termination preference. Both are active products with current manufacturing support, unlike the obsolete AMT303-V.

Q: How do the actuator specifications compare across all three parts?

A: All three encoders feature identical 2mm ~ 8mm open center actuator specifications, ensuring mechanical compatibility in existing mounting configurations.
