AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 pulses per revolution with commutation output in a right-angle chassis mount orientation. This encoder operates at 5V supply voltage and features an open center actuator design with terminal pin termination.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring incremental encoder functionality with these specific electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental
• Manufacturer: CUI Devices
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• RoHS and REACH Compliance: Maintained

The substitute parts AMT313Q-V and AMT313S-V share the same encoder classification, supply voltage, actuator design, mounting configuration, and orientation as the AMT303-V. Both substitutes maintain equivalent environmental compliance certifications. The primary difference lies in pulses per revolution capability: while the AMT303-V is fixed at 800 PPR, the substitute parts feature programmable PPR, allowing configuration to match the original specification or other system requirements.

Parameter Comparison

Engineering Selection Recommendations

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

AMT313Q-V maintains terminal pin termination, matching the original AMT303-V connection method. This substitute is suitable for direct integration into existing wiring harnesses and PCB layouts designed for the AMT303-V.

AMT313S-V provides connector-based termination, offering a different connection interface. This configuration may require harness or connector adaptation depending on system design.

Both substitutes support programmable pulses per revolution, enabling configuration to the original 800 PPR specification or alternative values as system requirements dictate. Both maintain current product status with active manufacturing and inventory availability. Compliance certifications (ROHS3, REACH Unaffected) exceed or match the original part requirements.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the AMT303-V's 800 PPR specification?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 800 PPR to match the original AMT303-V specification.

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

A: The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. All other electrical and mechanical parameters are equivalent.

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

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

Q: Do the substitute parts meet the same compliance requirements as the AMT303-V?

A: Yes. Both AMT313Q-V and AMT313S-V maintain ROHS3 compliance and REACH Unaffected status, meeting or exceeding the original part's environmental compliance certifications.

Q: What supply voltage do the substitute parts require?

A: Both substitute parts operate at 5V supply voltage, matching the AMT303-V requirement.

Q: Are the substitute parts currently available?

A: Yes. Both AMT313Q-V (1349 units) and AMT313S-V (1045 units) are in active production with current inventory availability.
