AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 400 pulses per revolution with commutation output, 4-pole configuration, and line driver capability. 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 configuration

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 400 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 The AMT303LD-V is obsolete, making the AMT313Q-V the appropriate long-term alternative.

Compliance: Both parts maintain equivalent environmental compliance. The AMT313Q-V achieves ROHS3 Compliant status, which supersedes the RoHS Compliant designation of the AMT303LD-V. Both parts are REACH Unaffected and classified under ECCN EAR99.

Mechanical and Electrical Compatibility: The AMT313Q-V preserves all critical mechanical interfaces (chassis mount, right-angle orientation, 2mm ~ 8mm open center actuator) and electrical specifications (5V supply, terminal pin termination, commutation output). The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility while maintaining the capability to operate at 400 PPR when configured accordingly.

Frequently Asked Questions (FAQ)

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

A: Yes, the AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V across all interface parameters. The programmable resolution of the AMT313Q-V can be configured to match the 400 PPR specification of the original part.

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

A: The AMT303LD-V has a fixed 400 pulses per revolution output, while the AMT313Q-V features programmable resolution. Both maintain identical mechanical mounting, electrical supply requirements, and output commutation characteristics.

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

A: The AMT303LD-V is supplied in standard packaging, while the AMT313Q-V is packaged in a Box configuration. Both use terminal pin termination suitable for chassis mount applications.

Q: Does the AMT313Q-V meet current environmental compliance standards?

A: Yes. The AMT313Q-V is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The AMT303LD-V, while RoHS Compliant, is obsolete and no longer actively supported.

Q: What supply voltage is required for the AMT313Q-V?

A: The AMT313Q-V operates at 5V supply voltage, identical to the AMT303LD-V.
