AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 192 pulses per revolution (PPR) and 2-pole commutation output in a right-angle orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary 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

The AMT313Q-V and AMT313S-V meet these core substitution criteria. Both are incremental encoders from CUI Devices with commutation output, 5V supply voltage, identical actuator specifications, and right-angle orientation. The key distinction between these substitutes is the pulses per revolution capability: while the original AMT303-V provides fixed 192 PPR output, the substitute models feature programmable PPR, allowing configuration to match the original specification or adapt to system requirements.

Parameter Comparison

Engineering Selection Recommendations

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

AMT313Q-V features terminal pin termination, matching the original AMT303-V connection style and providing direct compatibility with existing harnesses and PCB layouts designed for the main part.

AMT313S-V features connector termination, offering modular connection advantages for applications requiring frequent encoder replacement or reconfiguration.

Both substitutes maintain full compliance with RoHS3 and REACH regulations, exceeding the original part's RoHS compliance status. The programmable PPR capability of both substitutes provides system flexibility while supporting configuration to the original 192 PPR specification.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to output 192 PPR like the original AMT303-V?

A: Yes. Both substitute models feature programmable pulses per revolution, allowing configuration to match the original 192 PPR specification through appropriate programming.

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

A: The termination style differs. AMT313Q-V uses terminal pins, while AMT313S-V uses a connector interface. Both maintain identical electrical and mechanical specifications for encoder function.

Q: Are the substitute parts compatible with existing AMT303-V mounting locations?

A: Yes. Both substitutes share identical mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator specifications (2mm ~ 8mm Open Center), ensuring mechanical compatibility with original installation points.

Q: Do the substitute encoders maintain the same supply voltage requirement?

A: Yes. All three encoders operate at 5V supply voltage.

Q: What compliance improvements do the substitutes offer?

A: The AMT313Q-V and AMT313S-V are ROHS3 Compliant, representing an upgrade from the original AMT303-V RoHS Compliant status. Both maintain REACH Unaffected status identical to the original part.
