AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 96 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The AMT303-V operates at 5V supply voltage with an open center actuator design and terminal pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AMT303-V is determined by the following critical parameters that must remain consistent:

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Actuator Type: 2mm ~ 8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Output Type: Commutation output capability (required match)

The substitute parts AMT313Q-V and AMT313S-V satisfy these core requirements. Both are active-status incremental encoders from CUI Devices' AMT31 series with programmable pulses per revolution, allowing configuration to match the original 96 PPR specification. Both maintain identical supply voltage, actuator geometry, mounting configuration, and orientation as the AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active-status alternatives to the obsolete AMT303-V. The primary distinction between these substitutes is termination style: AMT313Q-V retains terminal pin termination matching the original design, while AMT313S-V uses connector termination.

For direct replacement in existing systems with terminal pin connections, AMT313Q-V is the preferred selection. Both substitutes feature programmable pulses per revolution, enabling configuration to the original 96 PPR specification. Both meet ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 96 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 96 PPR to match the original encoder specification.

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

A: The termination style differs. AMT313Q-V uses terminal pins, matching the AMT303-V connection method. AMT313S-V uses connector termination, requiring interface modification.

Q: Are the substitute parts compatible with existing 5V supply systems?

A: Yes. Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, identical to the AMT303-V.

Q: Do the substitute encoders maintain the same physical mounting configuration?

A: Yes. Both substitutes feature right-angle orientation, chassis mount configuration, and 2mm ~ 8mm open center actuator design, matching the AMT303-V mechanical interface.

Q: What compliance certifications apply to the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.
