AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured with 192 pulses per revolution and 10-pole commutation output in a right-angle orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The encoder operates at 5V supply voltage with a 2mm to 8mm open center actuator and chassis mount configuration suitable for motor integration applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by alignment across 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 to 8mm open center configuration
• Mounting Type: Must support Chassis Mount and Motors applications
• Orientation: Must be Right Angle
• Mechanical Compatibility: Termination style and connector type must be compatible with existing circuit board or harness interfaces

The substitute parts AMT313Q-V and AMT313S-V meet these core electrical and mechanical requirements. Both are active-status components from the AMT31 series, offering programmable pulses per revolution capability, which provides functional equivalence with enhanced flexibility compared to the fixed 192 PPR specification of the AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for applications requiring direct terminal pin termination. This part maintains identical termination methodology to the AMT303-V while offering programmable PPR configuration. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance exceeds the RoHS compliance level of the original part.

AMT313S-V serves as an alternative for designs that can accommodate connector-based termination. This configuration may simplify integration in modular or field-replaceable applications. Like the AMT313Q-V, it provides active status and ROHS3 compliance.

Both substitute parts require configuration of the programmable PPR parameter to 192 to achieve functional equivalence with the original AMT303-V specification. Verify connector pinout and signal mapping compatibility with existing system interfaces before implementation.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be used interchangeably with AMT303-V?

A: Both parts satisfy the core electrical and mechanical requirements. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector. Selection depends on your circuit board interface design. Both require PPR programming to 192 to match the original specification.

Q: What is the significance of programmable PPR in the substitute parts?

A: The AMT313Q-V and AMT313S-V offer configurable pulses per revolution, whereas the AMT303-V is fixed at 192 PPR. This provides design flexibility for future applications while maintaining compatibility with existing 192 PPR system requirements through proper configuration.

Q: Are there compliance differences between the original and substitute parts?

A: The AMT303-V carries RoHS Compliant status, while both substitutes are ROHS3 Compliant, representing an enhanced compliance level. All three parts are REACH Unaffected and classified under ECCN EAR99.

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

A: Obsolete status indicates the manufacturer has discontinued production. The AMT313 series represents the current active product line from CUI Devices for this encoder category, making it the recommended path for new designs and legacy system replacements.

Q: Does termination style affect electrical performance?

A: Termination style (terminal pins versus connector) does not affect electrical performance. Selection is based on mechanical integration requirements and existing system interfaces. Ensure proper signal mapping and connector compatibility during implementation.
