AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 512 pulses per revolution (PPR) and 2-pole commutation output in a right-angle orientation. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The encoder operates at 5V supply voltage with a chassis mount configuration suitable for motor applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Output Type: Must support Commutation output
• Supply Voltage: Must operate at 5V
• Actuator Type: Must accommodate 2mm ~ 8mm Open Center
• Mounting Type: Must support Chassis Mount, Motors configuration
• Orientation: Must be Right Angle
• Termination Style: Terminal Pins or Connector acceptable

The AMT313Q-V and AMT313S-V meet these core substitution criteria. Both are active-status incremental encoders from CUI Devices with programmable pulses per revolution, allowing configuration to match the 512 PPR specification of the AMT303-V. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement applications. It maintains terminal pin termination identical to the AMT303-V, minimizing PCB redesign requirements. The programmable PPR capability allows configuration to the original 512 PPR specification. This part carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

AMT313S-V serves as an alternative where connector-based termination is acceptable or preferred. This configuration may reduce assembly complexity in applications where connector interfaces are already established. Like the AMT313Q-V, it supports programmable PPR and maintains active product status with full compliance certifications.

Both substitutes provide superior long-term support compared to the obsolete AMT303-V, with active manufacturing status and current regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V and AMT313S-V be configured to match the 512 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 512 PPR to match the original specification.

Q: What is the primary difference between AMT313Q-V and AMT313S-V?

A: The termination interface differs. AMT313Q-V uses terminal pins (matching the AMT303-V), while AMT313S-V uses a connector interface. All other electrical and mechanical parameters are equivalent.

Q: Which substitute requires less redesign effort?

A: The AMT313Q-V requires minimal redesign due to identical terminal pin termination. The AMT313S-V requires connector interface accommodation but may simplify assembly workflows in connector-based systems.

Q: Are both substitutes compliant with current regulatory standards?

A: Yes. Both AMT313Q-V and AMT313S-V carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Q: Why is the AMT303-V classified as obsolete?

A: The AMT303-V has been discontinued by the manufacturer. The AMT313 series provides equivalent functionality with active production status and enhanced programmability.
