AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 500 pulses per revolution with commutation output, CCW polarity, and 2-pole line driver configuration. This component is designed for chassis mount and motor applications with right-angle orientation and terminal pin termination.

The AMT303LD-V carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Output Configuration: Must support commutation output with line driver capability

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than fixed 500 PPR, it can be configured to operate at 500 PPR, maintaining functional equivalence within the specified parameter constraints.

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V based on matching core electrical and mechanical parameters. Key considerations for selection:

Product Status: The AMT313Q-V maintains active product status with CUI Devices, ensuring ongoing availability and supply chain continuity compared to the obsolete AMT303LD-V.

Compliance: Both parts maintain RoHS compliance. The AMT313Q-V carries ROHS3 certification, representing current compliance standards.

Programmable Configuration: The AMT313Q-V offers programmable pulses per revolution, allowing configuration to match the 500 PPR specification of the original part while providing flexibility for future design modifications.

Electrical and Mechanical Compatibility: Both encoders share identical supply voltage (5V), actuator type (2mm ~ 8mm Open Center), mounting configuration (Chassis Mount, Motors), orientation (Right Angle), and termination style (Terminal Pins).

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modification?

A: The AMT313Q-V matches all critical mechanical and electrical parameters. The programmable PPR feature must be configured to 500 PPR to achieve functional equivalence with the fixed 500 PPR specification of the AMT303LD-V.

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

A: The AMT313Q-V's programmable PPR capability allows configuration flexibility. For direct replacement of the AMT303LD-V, the substitute must be programmed to 500 PPR. This feature also enables the part to serve multiple applications requiring different PPR values.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is specified with dash packaging, while the AMT313Q-V is supplied in Box packaging. Both maintain identical mechanical form factors and terminal pin configurations.

Q: How do the output specifications compare?

A: Both parts provide commutation output with line driver capability. The AMT303LD-V specifies CCW polarity with 2-pole configuration, while the AMT313Q-V provides commutation output. Verification of polarity and pole configuration for the substitute part is necessary during integration.

Q: What compliance certifications apply to both parts?

A: Both the AMT303LD-V and AMT313Q-V are RoHS compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8543.70.4500. The AMT313Q-V carries current ROHS3 certification.
