AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 200 pulses per revolution (PPR) output. This encoder features a right-angle orientation, chassis mount configuration, and 5V supply voltage operation. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this encoder type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on alignment across the following critical parameters:

• Encoder type (Incremental)
• Supply voltage (5V)
• Actuator type (2mm ~ 8mm Open Center)
• Mounting configuration (Chassis Mount, Motors)
• Orientation (Right Angle)
• Output type (Commutation)
• Manufacturer (CUI Devices)

The AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active-status products from the AMT31 series, ensuring ongoing availability and support. The primary distinction between substitutes relates to termination style and pulses per revolution configuration.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for AMT303-V applications requiring terminal pin termination. Both encoders share identical termination style, mounting configuration, and supply voltage. The AMT313Q-V features programmable pulses per revolution, allowing configuration to 200 PPR to match the fixed 200 PPR specification of the AMT303-V. Active product status ensures continued manufacturer support and component availability.

AMT313S-V serves as an alternative substitute where connector-based termination is acceptable or preferred. This encoder provides the same core functionality with connector termination instead of terminal pins. Programmable PPR capability allows configuration matching. Active product status provides long-term supply chain stability.

Both substitutes carry ROHS3 compliance, exceeding the RoHS compliance of the obsolete AMT303-V, and maintain REACH unaffected status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V directly replace AMT303-V in existing designs?

A: Yes, for applications using terminal pin termination. Both encoders share identical supply voltage (5V), actuator type (2mm ~ 8mm Open Center), mounting type (Chassis Mount, Motors), and orientation (Right Angle). The AMT313Q-V's programmable PPR can be configured to 200 PPR to match the fixed specification of AMT303-V.

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 configuration. AMT313S-V uses a connector interface. Both provide programmable PPR functionality and identical electrical and mechanical parameters otherwise.

Q: Does the programmable PPR feature of substitute parts affect compatibility?

A: No. The programmable PPR of AMT313Q-V and AMT313S-V can be configured to 200 PPR, matching the fixed 200 PPR output of AMT303-V. This flexibility provides equivalent functionality for the original application.

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

A: The substitute parts (AMT313Q-V and AMT313S-V) carry ROHS3 compliance, which exceeds the RoHS compliance of the obsolete AMT303-V. Both maintain REACH unaffected status. This represents an improvement in regulatory compliance.

Q: Why is product status relevant for substitution?

A: The AMT303-V is obsolete, meaning CUI Devices no longer manufactures or supports this part. AMT313Q-V and AMT313S-V are active products with ongoing manufacturer support, ensuring availability for replacement and new applications.
