AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 pulses per revolution with commutation output, 4-pole configuration, 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 shaft
• Mounting Configuration: Chassis mount, motor applications
• Orientation: Right angle
• Termination: Terminal pins
• Output Characteristics: Commutation output with line driver capability
• Compliance Standards: RoHS and REACH compliance status

The AMT313Q-V is identified as a substitute part. While it maintains compatibility across mounting, orientation, termination, voltage, and actuator specifications, it differs in pulses per revolution capability (programmable versus fixed 1024 PPR) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V serves as an active substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply voltage, and termination characteristics, enabling direct form-fit-function replacement in chassis mount and motor applications.

The AMT313Q-V maintains ROHS3 compliance, exceeding the RoHS compliance level of the original part. Both components carry unlimited moisture sensitivity classification and REACH unaffected status.

The primary technical distinction is the pulses per revolution specification: the AMT303LD-V provides fixed 1024 PPR output, while the AMT313Q-V offers programmable PPR capability. System designs requiring fixed 1024 PPR resolution must confirm that the programmable configuration of the substitute part can be set to this value within the application environment.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V in existing applications?

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V across mounting type, orientation, voltage supply, and termination style. Compatibility depends on whether the application can accommodate the programmable PPR feature of the substitute part and configure it to the required resolution.

Q: What are the key compatibility criteria for substitution?

A: Substitution is valid when the following parameters match: 5V supply voltage, incremental encoder type, 2mm ~ 8mm open center actuator, chassis mount and motor mounting capability, right-angle orientation, and terminal pin termination. Output type and PPR specifications must be evaluated against application requirements.

Q: How do the RoHS compliance levels differ between these parts?

A: The AMT303LD-V carries RoHS Compliant status, while the AMT313Q-V carries ROHS3 Compliant status. ROHS3 represents an updated compliance standard and does not prevent substitution; it indicates enhanced regulatory alignment.

Q: What is the significance of the programmable PPR feature in the AMT313Q-V?

A: The AMT313Q-V allows PPR configuration through programming, whereas the AMT303LD-V provides fixed 1024 PPR output. Applications requiring exactly 1024 PPR must confirm that the substitute part's programmable setting can be configured to this value.

Q: Are both parts available for procurement?

A: The AMT303LD-V is obsolete with 1015 pieces in stock. The AMT313Q-V is active with 1349 pieces in stock, making it the recommended choice for new designs and ongoing procurement.
