AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 400 pulses per revolution with commutation output, CW 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 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility 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 Type: Must support Commutation output with compatible polarity and line driver configuration

The AMT313Q-V meets these substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than fixed 400 PPR, it can be configured to operate at 400 PPR, making it functionally equivalent for applications requiring this specific resolution.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V. Both components are manufactured by CUI Devices and share identical mechanical and electrical interfaces. The AMT313Q-V maintains active product status, ensuring continued availability and supply chain reliability.

The AMT313Q-V provides enhanced flexibility through programmable pulse-per-revolution configuration, allowing it to be set to 400 PPR to match the original specification. Both parts maintain equivalent RoHS compliance and REACH status, with the substitute offering ROHS3 certification.

Selection of the AMT313Q-V eliminates obsolescence risk while preserving full functional compatibility with existing system designs.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mounting, orientation, termination, and supply voltage specifications. The AMT313Q-V can be configured to 400 PPR to match the original part's resolution.

Q: What is the primary difference between these two parts?

A: The AMT303LD-V has a fixed 400 PPR output, while the AMT313Q-V features programmable PPR. This programmability allows the substitute to be configured for the original specification or adapted to alternative resolutions as needed.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 certification, representing a more current compliance standard than the obsolete AMT303LD-V.

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

A: Obsolescence indicates the part is no longer in active production. The AMT313Q-V serves as the active replacement within the CUI Devices encoder product line.

Q: Are packaging differences relevant to substitution?

A: Packaging differences do not affect functional substitution. Both parts use terminal pin termination suitable for chassis mount and motor applications.
