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 12-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback at 5V supply voltage.

The AMT303-V carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications currently utilizing this encoder model.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Output Type: Must support Commutation output
• Supply Voltage: Must operate at 5V
• Actuator Type: Must accommodate 2mm ~ 8mm Open Center
• Mounting Type: Must support Chassis Mount and Motors applications
• Orientation: Must be Right Angle
• Compliance: Must maintain RoHS and REACH compliance status

The substitute parts AMT313Q-V and AMT313S-V satisfy these core compatibility criteria. Both are active-status incremental encoders from CUI Devices' AMT31 series with programmable pulse-per-revolution configuration, enabling functional equivalence despite the fixed 800 PPR specification of the original AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active-status alternatives to the obsolete AMT303-V. The primary distinction between these substitutes is termination style:

AMT313Q-V features Terminal Pins termination, matching the original AMT303-V connection method. This option minimizes integration changes for existing designs.

AMT313S-V features Connector termination, providing an alternative connection interface. Selection depends on application-specific wiring requirements.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements equivalent to or exceeding the original part. The programmable pulses-per-revolution capability of both substitutes provides design flexibility beyond the fixed 800 PPR specification of the AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy the core electrical and mechanical compatibility parameters: incremental encoder type, commutation output, 5V supply, identical actuator and mounting specifications, and right-angle orientation. The primary difference is termination style. AMT313Q-V uses terminal pins; AMT313S-V uses a connector. Selection depends on your application's connection requirements.

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

A: The AMT303-V operates at a fixed 800 PPR. The AMT313Q-V and AMT313S-V offer programmable PPR configuration, allowing adjustment to match the 800 PPR specification or other values as needed for your application.

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

A: The original AMT303-V is RoHS Compliant. Both substitutes are ROHS3 Compliant, representing an updated compliance standard. Both maintain REACH Unaffected status. These differences do not affect functional compatibility.

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

A: Obsolete status indicates the manufacturer has discontinued production. The AMT313Q-V and AMT313S-V are active-status parts, ensuring ongoing availability and supply chain continuity.

Q: Does termination style affect electrical performance?

A: Termination style affects physical connection method only. Terminal pins and connector terminations both support the same electrical output specifications. Selection is based on integration requirements and existing wiring infrastructure.
