AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 96 pulses per revolution (PPR) and 4-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback at 5V supply voltage.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this encoder specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Must be Incremental
• Output Type: Must support Commutation output
• Voltage - Supply: Must operate at 5V
• Actuator Type: Must accommodate 2mm ~ 8mm Open Center
• Mounting Type: Must support Chassis Mount, Motors
• Orientation: Must be Right Angle
• RoHS & Environmental Compliance: Must meet or exceed RoHS and REACH requirements

The substitute parts AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active-status CUI Devices encoders from the AMT31 series with programmable pulses per revolution, allowing configuration to match the 96 PPR specification of the AMT303-V. Both maintain identical supply voltage, actuator type, mounting configuration, and environmental compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active-status alternatives to the obsolete AMT303-V. Both substitute parts exceed the original RoHS compliance level (ROHS3 vs. RoHS Compliant) and maintain full REACH compliance.

AMT313Q-V retains the terminal pin termination style of the original AMT303-V, providing direct mechanical and electrical compatibility with existing connector designs.

AMT313S-V uses a connector-based termination style, which differs from the original terminal pin configuration. This substitution requires connector interface adaptation in the application circuit.

Both parts feature programmable pulses per revolution, enabling configuration to the 96 PPR specification required by the AMT303-V application. Selection between these two substitutes depends on termination style compatibility with the existing system design.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly substituted for AMT303-V?

A: Both parts meet the core functional requirements: incremental encoder type, commutation output, 5V supply, identical actuator and mounting specifications, and right-angle orientation. The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

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

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to match the 96 PPR specification of the AMT303-V. This flexibility enables these active-status parts to fulfill the original encoder resolution requirement.

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

A: The substitute parts (AMT313Q-V and AMT313S-V) carry ROHS3 compliance, which exceeds the RoHS Compliant rating of the AMT303-V. Both maintain REACH Unaffected status. These upgrades in compliance standards present no compatibility issues.

Q: Which substitute part should be selected for new designs?

A: Selection depends on termination interface requirements. If the application uses terminal pin connections, AMT313Q-V is the direct substitute. If connector-based termination is acceptable or preferred, AMT313S-V is a valid alternative. Both are active-status components with full inventory availability.

Q: Are there any mechanical compatibility concerns with these substitutes?

A: All three encoders share identical actuator type (2mm ~ 8mm Open Center), mounting type (Chassis Mount, Motors), and orientation (Right Angle). Mechanical compatibility is maintained across all three parts.
