AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 512 pulses per revolution with commutation output and line driver capability. This component is designed for chassis mount and motor applications with right-angle orientation and terminal pin termination.

The AMT303LD-V is classified as obsolete. 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 of the AMT303LD-V is based on the following critical parameters that must align for functional compatibility:

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

The AMT313Q-V is identified as a substitute part. While it maintains the same supply voltage, actuator type, mounting configuration, orientation, and termination style, it features programmable pulses per revolution rather than the fixed 512 PPR of the AMT303LD-V. This programmability allows the AMT313Q-V to be configured to match the original specification when required.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Both components share identical supply voltage, mechanical mounting characteristics, and environmental compliance ratings. The AMT313Q-V maintains active product status, ensuring ongoing availability and support.

The primary distinction is the programmable pulses per revolution feature of the AMT313Q-V, which can be configured to operate at 512 PPR to match the original specification. Both components meet RoHS and REACH compliance requirements and carry the same export classification (EAR99).

The AMT313Q-V is suitable for direct substitution in applications requiring 512 PPR operation, provided the system design accommodates the programmable configuration capability.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares all critical mechanical and electrical parameters with the AMT303LD-V, including supply voltage, mounting type, orientation, and termination style. The programmable pulses per revolution feature of the AMT313Q-V must be configured to 512 PPR to match the original specification.

Q: What is the significance of the programmable pulses per revolution in the AMT313Q-V?

A: The AMT313Q-V allows pulses per revolution to be set during configuration, providing flexibility for different application requirements. For substitution purposes, this parameter must be programmed to 512 PPR to maintain functional equivalence with the AMT303LD-V.

Q: Are there packaging differences between these components?

A: The AMT303LD-V is supplied in standard packaging, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination and are suitable for chassis mount and motor applications.

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. The AMT313Q-V carries ROHS3 compliance, representing the current RoHS standard.

Q: Why is the AMT303LD-V classified as obsolete?

A: The AMT303LD-V has been discontinued by the manufacturer. The AMT313Q-V, with its programmable configuration capability, represents the active product line replacement for this encoder family.
