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 and 8-pole line driver configuration. 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 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
• Output Type: Must support Commutation with Line Driver capability
• Voltage Supply: Must operate at 5V
• Actuator Type: Must accommodate 2mm ~ 8mm Open Center configuration
• Mounting Type: Must support Chassis Mount and Motors applications
• Orientation: Must be Right Angle
• Termination Style: Must use Terminal Pins

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 compatibility across all other critical mechanical and electrical parameters required for direct substitution in the specified application category.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Selection of the AMT313Q-V is supported by the following factors:

• Product Status: The AMT313Q-V maintains active product status, ensuring ongoing availability and manufacturing support from CUI Devices.
• Regulatory Compliance: The AMT313Q-V achieves ROHS3 Compliant status, meeting current environmental and regulatory requirements that exceed the RoHS Compliant designation of the original part.
• Mechanical Compatibility: All mechanical parameters—mounting type, orientation, actuator type, and termination style—are identical between the two encoders.
• Electrical Compatibility: Both encoders operate at 5V supply voltage and maintain commutation output capability with line driver configuration.
• Programmable Resolution: The AMT313Q-V offers programmable pulses per revolution, providing flexibility to configure the encoder to match the original 800 PPR specification or adapt to alternative resolution requirements within the application.

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 mounting, orientation, voltage, and termination parameters. The primary difference is the programmable pulses per revolution feature in the AMT313Q-V versus the fixed 800 PPR in the AMT303LD-V. Configuration of the AMT313Q-V to 800 PPR will provide functional equivalence.

Q: What is the significance of the programmable pulses per revolution in the AMT313Q-V?

A: The programmable feature allows the AMT313Q-V to be configured to match the original 800 PPR specification of the AMT303LD-V or to alternative resolution values as required by system design. This flexibility provides additional functionality beyond the original fixed-resolution encoder.

Q: Are there packaging differences between these encoders?

A: The AMT303LD-V is supplied in standard packaging, while the AMT313Q-V is supplied in Box packaging. Both use identical terminal pin termination and are compatible with the same mounting configurations.

Q: Does the ROHS3 Compliant status of the AMT313Q-V affect compatibility?

A: No. ROHS3 Compliance represents an enhanced regulatory standard that is fully backward compatible with applications designed for RoHS Compliant components. The upgrade in compliance status does not introduce incompatibility.

Q: What is the inventory status of these parts?

A: The AMT303LD-V has 1097 pieces in stock as new original inventory. The AMT313Q-V has 1349 pieces in stock as new original inventory. The active product status of the AMT313Q-V ensures continued availability for future procurement.
