AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 96 pulses per revolution with commutation output, CCW rotation, 6-pole configuration, and integrated line driver. 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 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
• 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 these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 96 PPR of the AMT303LD-V), it maintains compatibility across all mechanical, electrical, and interface parameters required for direct substitution in applications where the encoder resolution can be configured.

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 with CUI Devices, ensuring ongoing availability and support. The AMT303LD-V is obsolete, making the AMT313Q-V the appropriate long-term replacement.

Compliance: Both parts maintain equivalent environmental compliance. The AMT313Q-V achieves ROHS3 Compliant status, representing an advancement over the RoHS Compliant designation of the main part. Both parts are REACH Unaffected and classified under ECCN EAR99.

Electrical and Mechanical Compatibility: The AMT313Q-V preserves all critical interface parameters: 5V supply voltage, commutation output type, right-angle orientation, terminal pin termination, and identical actuator specifications (2mm ~ 8mm Open Center).

Resolution Configuration: The AMT313Q-V offers programmable pulses per revolution, allowing configuration to 96 PPR to match the original specification or adjustment to alternative resolutions as system requirements permit.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V across all interface parameters: mounting type, orientation, termination style, actuator type, and supply voltage. The programmable resolution of the AMT313Q-V can be configured to match the 96 PPR specification of the original part.

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

A: The AMT303LD-V provides a fixed 96 pulses per revolution output. The AMT313Q-V features programmable pulses per revolution, offering flexibility in resolution configuration while maintaining identical mechanical and electrical interfaces.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied in standard packaging. The AMT313Q-V is supplied in Box packaging. Both use identical terminal pin termination and mounting specifications.

Q: Does the AMT313Q-V support the same output type as the AMT303LD-V?

A: Both parts support commutation output type. The AMT303LD-V specifies commutation with CCW rotation, 6-pole configuration, and integrated line driver. The AMT313Q-V supports commutation output, maintaining compatibility with systems designed for the original part.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant (AMT303LD-V: RoHS Compliant; AMT313Q-V: ROHS3 Compliant), REACH Unaffected, and classified under ECCN EAR99. Both maintain MSL 1 (Unlimited) moisture sensitivity level.
