AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 500 pulses per revolution with 8-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
• Detent and Built-in Switch: Must match (No for both)
• Regulatory Compliance: RoHS and REACH status must be maintained

The substitute parts AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active-status incremental encoders from CUI Devices with programmable pulses per revolution, allowing configuration to match the 500 PPR specification of the AMT303-V. Both maintain identical supply voltage, actuator type, mounting configuration, and orientation requirements.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for the AMT303-V. Both components feature terminal pin termination, maintaining identical electrical interface requirements. The AMT313Q-V is an active product with programmable pulses per revolution, allowing configuration to the 500 PPR specification required by the AMT303-V application. ROHS3 compliance exceeds the original RoHS Compliant status, ensuring regulatory alignment with current manufacturing standards.

AMT313S-V is an alternative substitute with identical electrical and mechanical specifications to the AMT313Q-V, with the exception of termination style. This part features connector-based termination rather than terminal pins. Selection of the AMT313S-V requires mechanical interface redesign to accommodate the connector termination. This part is suitable only when connector-based termination is acceptable or preferred in the application design.

Both substitute parts maintain active product status, ensuring long-term availability and supply chain stability compared to the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303-V without design modifications?

A: The AMT313Q-V maintains identical electrical and mechanical interfaces, including 5V supply voltage, terminal pin termination, right-angle orientation, and 2mm ~ 8mm open center actuator compatibility. The programmable pulses per revolution must be configured to 500 PPR to match the AMT303-V specification. No design modifications are required for electrical or mechanical integration.

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

A: Both parts are functionally equivalent incremental encoders with programmable pulses per revolution and identical electrical specifications. The primary difference is termination style: AMT313Q-V uses terminal pins, while AMT313S-V uses a connector interface. Selection depends on the mechanical interface requirements of the application.

Q: Why is the AMT303-V obsolete, and what does this mean for component sourcing?

A: Obsolete status indicates the manufacturer has discontinued production of the AMT303-V. The substitute parts AMT313Q-V and AMT313S-V are active products from the same manufacturer, ensuring continued availability and support. Transitioning to an active substitute part is recommended for new designs and long-term supply chain reliability.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant, which exceeds the RoHS Compliant status of the original AMT303-V. Both parts are also REACH Unaffected, maintaining regulatory compliance with current environmental standards.

Q: Can the pulses per revolution of the substitute parts be configured to match the AMT303-V?

A: Yes. Both AMT313Q-V and AMT313S-V feature programmable pulses per revolution. Configuration to 500 PPR is supported, matching the fixed 500 PPR specification of the AMT303-V.
