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 configuration, and 8-pole line driver capability. 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
• Mounting Type: Must support Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Voltage Supply: Must be 5V
• Actuator Type: Must accommodate 2mm ~ 8mm Open Center
• Output Configuration: Must support Commutation output with compatible pole and line driver specifications

The AMT313Q-V meets these core substitution criteria while offering programmable pulses per revolution capability, providing flexibility for applications requiring variable resolution.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and core functional specifications. The AMT313Q-V maintains full compatibility with existing mechanical and electrical interfaces.

The substitute part carries Active product status, ensuring long-term availability and supply chain continuity. Both components meet equivalent compliance standards: RoHS compliance (with the substitute meeting ROHS3 specification), REACH unaffected status, and identical export classification (EAR99). Moisture sensitivity levels are identical at MSL 1 (Unlimited).

The primary functional difference is the programmable pulses per revolution capability of the AMT313Q-V, which accommodates the fixed 500 PPR specification of the original part while offering additional resolution flexibility for future design iterations.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mounting type (Chassis Mount, Motors), orientation (Right Angle), termination style (Terminal Pins), supply voltage (5V), and actuator type (2mm ~ 8mm Open Center). Mechanical and electrical interfaces are compatible.

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

A: The AMT303LD-V provides a fixed 500 pulses per revolution output. The AMT313Q-V offers programmable pulses per revolution, allowing configuration to match the 500 PPR specification or other resolutions as needed.

Q: Does the substitute part meet the same compliance requirements?

A: Yes. Both parts are RoHS compliant, REACH unaffected, and classified as EAR99 for export purposes. The substitute meets ROHS3 specification, which is a more recent compliance standard. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the original part obsolete?

A: The AMT303LD-V is listed as obsolete by the manufacturer. The AMT313Q-V, with Active product status, represents the current equivalent offering from CUI Devices for this encoder category.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with standard packaging. The AMT313Q-V is supplied in Box packaging. Both are suitable for component integration and storage.
