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 commutation output in a right-angle chassis mount orientation. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives from the active product portfolio. Substitute parts must maintain compatibility across electrical specifications, mechanical mounting interfaces, and output characteristics to ensure direct replacement capability in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by alignment across the following critical parameters:

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Pulses per Revolution: Fixed at 500 PPR for AMT303-V; substitute parts with programmable PPR capability are acceptable provided 500 PPR configuration is supported

The identified substitute parts AMT313Q-V and AMT313S-V meet these core electrical and mechanical compatibility criteria. Both feature programmable pulse-per-revolution settings, enabling configuration to match the 500 PPR specification of the original component. The primary distinction between substitutes relates to termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V employs a connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply chain continuity for applications currently using the obsolete AMT303-V. Both substitutes maintain full compliance with RoHS3 and REACH requirements, meeting modern regulatory standards.

AMT313Q-V is the preferred direct replacement when terminal pin termination is required, as it matches the original AMT303-V interface specification. This part maintains identical electrical and mechanical characteristics while offering programmable PPR configuration.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. The connector interface may simplify integration in modular system designs, though it requires interface compatibility verification in the target application.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to 500 PPR to match the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses-per-revolution capability, allowing configuration to 500 PPR through appropriate programming procedures. Consult the respective product datasheets for configuration methodology.

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

A: The termination interface differs. AMT313Q-V uses terminal pins, matching the original AMT303-V configuration. AMT313S-V employs a connector interface. All other electrical and mechanical specifications are identical.

Q: Are the substitute parts compatible with existing PCB layouts designed for AMT303-V?

A: AMT313Q-V maintains terminal pin termination and is mechanically compatible with existing designs. AMT313S-V requires interface adapter or PCB redesign due to connector termination. Verify mounting dimensions and pin assignments in application-specific designs.

Q: Do the substitute parts maintain the same supply voltage and power requirements?

A: Yes. All three parts operate at 5V supply voltage with identical actuator type and mounting specifications.

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 requirements for electronic components.
