AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 400 pulses per revolution with commutation output in counter-clockwise direction. The encoder features a 10-pole right-angle orientation and operates at 5V supply voltage. This part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs.

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
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Configuration: Must support Commutation output
• Detent and Built-in Switch: Must match (No for both)

The substitute parts AMT313Q-V and AMT313S-V satisfy these core compatibility criteria. Both are active-status incremental encoders from CUI Devices with programmable pulses per revolution, allowing configuration to match the 400 PPR specification of the AMT303-V. The key distinction between substitutes lies in termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active-status alternatives to the obsolete AMT303-V. Selection between these substitutes depends on termination interface requirements:

AMT313Q-V is the direct functional equivalent when terminal pin termination is required. This part maintains identical electrical and mechanical interfaces to the AMT303-V while offering programmable PPR configuration and ROHS3 compliance.

AMT313S-V provides the same core functionality with connector-based termination. This configuration is suitable for applications where connector interfaces are preferred or standardized.

Both substitutes carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The programmable PPR feature of both alternatives provides design flexibility beyond the fixed 400 PPR specification of the AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 400 PPR output of AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 400 PPR to match the original AMT303-V specification.

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 interface. AMT313S-V uses a connector interface. All other electrical and mechanical parameters are identical.

Q: Are the substitute parts compatible with existing AMT303-V mounting locations?

A: Yes. Both substitutes maintain identical mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator specifications (2mm ~ 8mm Open Center), ensuring mechanical compatibility.

Q: Do the substitute parts meet current compliance standards?

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

Q: Which substitute should be selected for direct replacement in existing designs?

A: AMT313Q-V is recommended for direct replacement due to matching terminal pin termination style. If connector termination is required by the application, AMT313S-V is the appropriate selection.
