AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 800 pulses per revolution with commutation output, CCW rotation, 6-pole configuration, and integrated line driver. The unit 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 applications currently utilizing this encoder model.

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
• Mechanical Compatibility: Identical form factor and interface

The AMT313Q-V meets these substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 800 PPR of the AMT303LD-V, it maintains electrical and mechanical compatibility across all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

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

Product Status: The AMT313Q-V maintains active product status, ensuring ongoing availability and manufacturer support, whereas the AMT303LD-V is obsolete.

Compliance: Both parts maintain equivalent RoHS and REACH compliance status. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards.

Electrical Compatibility: Both encoders operate at 5V supply voltage with identical commutation output architecture and terminal pin termination.

Mechanical Compatibility: Both units feature identical actuator type (2mm ~ 8mm Open Center), mounting configuration (Chassis Mount, Motors), and right-angle orientation.

Functional Difference: The AMT313Q-V provides programmable pulses per revolution, whereas the AMT303LD-V is fixed at 800 PPR. Applications requiring the specific 800 PPR output must configure the AMT313Q-V accordingly during implementation.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V across all mounting, orientation, and termination parameters. The primary difference is the programmable pulses per revolution feature on the AMT313Q-V. Applications must configure the AMT313Q-V to output 800 PPR to match the original AMT303LD-V specification.

Q: What are the key compatibility parameters for substitution?

A: Substitution is valid when the following parameters match: Encoder Type (Incremental), Supply Voltage (5V), Actuator Type (2mm ~ 8mm Open Center), Mounting Type (Chassis Mount, Motors), Orientation (Right Angle), Termination Style (Terminal Pins), and Output Type (Commutation).

Q: Does the AMT313Q-V maintain the same packaging as the AMT303LD-V?

A: The AMT313Q-V is supplied in Box packaging. Verify packaging requirements for your application, as this may differ from the original AMT303LD-V packaging specification.

Q: Are there compliance differences between these parts?

A: Both parts maintain RoHS and REACH compliance. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards, while the AMT303LD-V is RoHS Compliant. Both parts carry identical Moisture Sensitivity Level (MSL 1 - Unlimited).

Q: Why is the AMT303LD-V obsolete?

A: The AMT303LD-V carries obsolete product status. The AMT313Q-V represents the active equivalent offering from CUI Devices with enhanced programmable functionality while maintaining core electrical and mechanical compatibility.
