AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 1000 pulses per revolution with 12-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 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications currently utilizing this encoder model.

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: Incremental (maintained across all substitutes)
• Output Type: Commutation configuration (maintained)
• Supply Voltage: 5V (maintained)
• Actuator Type: 2mm ~ 8mm Open Center (maintained)
• Mounting Type: Chassis Mount, Motors (maintained)
• Orientation: Right Angle (maintained)
• Pulses per Revolution: The AMT303-V specifies 1000 PPR; substitute parts feature programmable PPR capability, allowing configuration to 1000 PPR or alternative values as application requirements permit

The AMT313Q-V and AMT313S-V both maintain core electrical and mechanical compatibility with the AMT303-V while offering programmable pulse-per-revolution functionality. The primary distinction between these substitutes is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement of the AMT303-V. This part maintains terminal pin termination, matching the original connector interface. The AMT313Q-V carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The programmable PPR capability provides design flexibility while supporting fixed 1000 PPR configuration.

AMT313S-V serves as an alternative substitute when connector termination is acceptable or preferred in the application design. This part also maintains active product status and ROHS3 compliance. Selection of AMT313S-V requires verification that the connector interface is compatible with the existing circuit board or harness design.

Both substitutes are manufactured by CUI Devices and maintain electrical and mechanical compatibility with the obsolete AMT303-V across all critical parameters.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V and AMT313S-V be configured to operate at 1000 PPR like the original AMT303-V?

A: Yes. Both substitute parts feature programmable PPR capability, allowing configuration to 1000 PPR or other values as required by the application.

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

A: The termination style differs. The AMT313Q-V uses terminal pins, matching the AMT303-V interface. The AMT313S-V uses connector termination. All other electrical and mechanical parameters remain identical.

Q: Are the substitute parts compatible with existing PCB designs using the AMT303-V?

A: The AMT313Q-V is directly compatible with existing terminal pin interfaces. The AMT313S-V requires verification of connector compatibility with the circuit board design.

Q: What is the compliance status of the substitute parts?

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

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

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