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 integrated line driver functionality. 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 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
• Supply Voltage: 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

The AMT313Q-V meets all mandatory substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 512 PPR of the AMT303LD-V), this represents an enhancement rather than a limitation, as programmable resolution accommodates the original specification and provides additional flexibility for system configuration.

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V. Selection rationale is based on the following factors:

• Product Status Alignment: The AMT313Q-V maintains active product status, ensuring long-term availability and supply chain continuity.
• Compliance Enhancement: The AMT313Q-V achieves ROHS3 Compliant status, representing an improvement over the RoHS Compliant designation of the original part.
• Regulatory Consistency: Both parts maintain identical REACH Unaffected and EAR99 ECCN classifications.
• Functional Compatibility: All critical electrical and mechanical parameters align with the original specification, including 5V supply voltage, right-angle orientation, chassis mount configuration, and terminal pin termination.
• Resolution Flexibility: The programmable pulses per revolution feature of the AMT313Q-V accommodates the 512 PPR requirement of the original design while providing configuration flexibility for future applications.

Frequently Asked Questions (FAQ)

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

A: Yes. The AMT313Q-V meets all mandatory electrical and mechanical parameters of the AMT303LD-V, including supply voltage, output type, actuator type, mounting configuration, and termination style. The programmable resolution feature is compatible with the original 512 PPR specification.

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

A: The AMT303LD-V features fixed 512 pulses per revolution, while the AMT313Q-V provides programmable resolution. Both encoders share identical supply voltage, mounting type, orientation, and termination characteristics.

Q: Does the programmable resolution of the AMT313Q-V affect compatibility?

A: No. The programmable feature allows the AMT313Q-V to be configured to match the original 512 PPR specification. This represents a functional enhancement rather than a compatibility concern.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with terminal pin termination, while the AMT313Q-V is packaged in a box. Both use identical termination style and mounting configuration.

Q: What is the inventory status of these parts?

A: The AMT303LD-V (obsolete status) has 938 pieces in stock. The AMT313Q-V (active status) has 1,349 pieces in stock, providing greater long-term availability assurance.
