AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 192 pulses per revolution with 8-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm–8mm range).

The AMT303-V has reached obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring incremental encoder functionality with compatible electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional and mechanical compatibility:

• 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 (required match)
• Detent: No (required match)
• Built-in Switch: No (required match)
• Moisture Sensitivity Level: 1 (Unlimited) (required match)
• RoHS/REACH Compliance: Maintained across substitutes

The AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active-status incremental encoders with programmable pulses per revolution, allowing configuration to match or exceed the 192 PPR specification of the AMT303-V. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement of AMT303-V. This part maintains terminal pin termination, matching the original interface. The programmable pulses per revolution feature provides configuration flexibility to achieve the 192 PPR specification. Active product status ensures ongoing availability and supply chain support. ROHS3 compliance exceeds the original RoHS requirement.

AMT313S-V serves as an alternative substitute when connector-based termination is acceptable in the application design. This part offers identical electrical and mechanical compatibility with the exception of termination interface. Connector termination may simplify integration in modular or field-replaceable applications.

Both substitutes are manufactured by CUI Devices, maintaining design consistency and supplier continuity. Selection between AMT313Q-V and AMT313S-V depends solely on termination interface requirements of the target application.

Frequently Asked Questions (FAQ)

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

A: Both parts meet the core electrical and mechanical compatibility requirements. Selection depends on termination interface: AMT313Q-V uses terminal pins (direct match to AMT303-V), while AMT313S-V uses a connector. Choose based on your application's interface requirements.

Q: What is the significance of "programmable" pulses per revolution in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to 192 PPR or other values as needed. This provides flexibility beyond the fixed 192 PPR of the AMT303-V while maintaining full compatibility when configured to match.

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

A: Both substitutes maintain REACH Unaffected status and improve RoHS compliance to ROHS3 (versus RoHS Compliant on the original). Moisture Sensitivity Level remains 1 (Unlimited) across all parts.

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

A: Obsolete status indicates the part is no longer in active production. The identified substitutes (AMT313Q-V and AMT313S-V) are active-status parts that provide equivalent functionality with improved availability.

Q: Does termination style affect electrical performance?

A: Termination style (terminal pins versus connector) is a mechanical interface consideration only. Both AMT313Q-V and AMT313S-V deliver identical electrical output characteristics when properly configured.
