AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, designed for chassis mount and motor applications with right-angle orientation. This encoder provides 500 pulses per revolution output with commutation and line driver functionality. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

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 with compatible pole configuration

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 500 PPR of the AMT303LD-V, it maintains compatibility across all mechanical, electrical, and interface parameters. The programmable capability of the substitute provides operational flexibility for system integration.

Engineering Selection Recommendations

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

Product Status: The AMT303LD-V is obsolete, while the AMT313Q-V maintains active product status with current manufacturing support and availability.

Compliance: Both components meet RoHS requirements. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards. Both components are REACH Unaffected and carry EAR99 ECCN classification.

Electrical Compatibility: Both encoders operate at 5V supply voltage with identical mechanical interfaces (2mm ~ 8mm open center actuator, right-angle orientation, terminal pin termination).

Functional Capability: The AMT313Q-V provides programmable pulses per revolution, enabling configuration to 500 PPR to match the original AMT303LD-V specification or alternative PPR values as system requirements permit.

Availability: The AMT313Q-V is in active production with documented inventory availability, ensuring supply chain continuity for replacement and new applications.

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 interface parameters. The programmable PPR feature of the substitute requires configuration to 500 PPR to match the original specification. No physical modifications to mounting or termination are required.

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

A: The AMT303LD-V provides fixed 500 PPR output, while the AMT313Q-V offers programmable PPR selection. Both maintain identical supply voltage, mechanical mounting, orientation, and termination characteristics.

Q: Are there packaging differences between the AMT303LD-V and AMT313Q-V?

A: The AMT303LD-V packaging is listed as standard, while the AMT313Q-V is supplied in Box packaging. Both use identical terminal pin termination for circuit integration.

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

A: The programmable capability is an enhancement that does not compromise compatibility. The substitute can be configured to operate at 500 PPR, matching the original encoder specification, or at alternative PPR values if system design permits.

Q: What compliance certifications apply to both encoders?

A: Both encoders are RoHS compliant, REACH Unaffected, and classified as EAR99 for export control purposes. The AMT313Q-V meets current ROHS3 standards. Both components carry Moisture Sensitivity Level 1 (Unlimited).
