AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 250 pulses per revolution with commutation output in counter-clockwise (CCW) configuration. This encoder is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is based on the following critical parameters that must remain consistent across alternative components:

• Encoder Type: Incremental operation
• Voltage Supply: 5V operation
• Actuator Type: 2mm ~ 8mm Open Center compatibility
• Mounting Configuration: Chassis Mount, Motors
• Orientation: Right Angle
• Output Compatibility: Commutation output capability
• Environmental Compliance: RoHS and REACH compliance status

The substitute parts AMT313Q-V and AMT313S-V maintain these core electrical and mechanical parameters. Both alternatives feature programmable pulses per revolution, allowing configuration to match the original 250 PPR specification when required. The primary distinction between substitutes lies in termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply chain continuity for applications currently using the obsolete AMT303-V. Both substitutes maintain full compliance with ROHS3 and REACH regulations, exceeding the original RoHS Compliant status of the AMT303-V.

AMT313Q-V is the direct functional equivalent when terminal pin termination is required. The programmable pulses per revolution feature allows configuration to the original 250 PPR specification, maintaining identical electrical interface characteristics.

AMT313S-V provides an alternative for applications where connector-based termination is acceptable or preferred. The connector interface may simplify integration in modular system designs while maintaining all core electrical and mechanical compatibility parameters.

Selection between the two substitutes should be based on termination interface requirements of the target application. Both alternatives satisfy the core functional and compliance requirements for replacement of the AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both substitutes maintain the same encoder type, output capability, voltage supply, actuator type, mounting configuration, and orientation as the original. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector. Selection depends on the termination interface required by your application.

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 match the original 250 PPR specification of the AMT303-V. This flexibility enables these parts to function as direct replacements without requiring system redesign.

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

A: The substitute parts (AMT313Q-V and AMT313S-V) carry ROHS3 Compliant status, which represents an updated compliance standard compared to the original RoHS Compliant designation. Both maintain REACH Unaffected status. This represents an improvement in regulatory alignment for new designs.

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

A: Obsolete status indicates the part is no longer in active production. The AMT313 series represents the current generation of equivalent encoders from CUI Devices, offering the same core functionality with updated compliance certifications and active manufacturing support.

Q: Does termination style affect electrical performance?

A: Termination style (terminal pins versus connector) does not affect the electrical output characteristics or performance of the encoder. Selection should be based on integration requirements and interface compatibility with your system design.
