AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1000 pulses per revolution with commutation output, CW polarity, and 2-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 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility 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
• Output Type: Must support Commutation with line driver capability
• Pulses per Revolution: Must match 1000 PPR or provide programmable configuration to 1000 PPR
• Voltage - Supply: Must be 5V compatible
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must support Chassis Mount and Motors applications
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins

The AMT313Q-V qualifies as a substitute based on these parameters. While it features programmable PPR capability rather than fixed 1000 PPR, it can be configured to 1000 PPR, meeting the functional requirement. All other critical parameters align with the original specification.

Engineering Selection Recommendations

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

• Product Status: The AMT313Q-V maintains active product status, ensuring ongoing availability and supply chain continuity.
• Compliance Alignment: Both parts maintain equivalent RoHS and REACH compliance profiles, with the substitute meeting ROHS3 standards.
• Functional Equivalence: The programmable PPR capability of the AMT313Q-V provides flexibility to configure 1000 PPR operation, matching the fixed specification of the original part.
• Mechanical and Electrical Compatibility: All critical parameters including voltage supply, actuator type, mounting configuration, and termination style are identical between the two parts.

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. The programmable PPR feature must be configured to 1000 PPR to match the original specification. Verify that your application supports programmable encoder configuration before implementation.

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

A: The AMT303LD-V features fixed 1000 PPR output, while the AMT313Q-V provides programmable PPR configuration. Both parts share identical mechanical mounting, electrical supply requirements, and output commutation characteristics.

Q: Are there packaging differences between the original and substitute?

A: The AMT303LD-V is supplied with terminal pin termination. The AMT313Q-V is packaged in a box configuration. Both use identical terminal pin termination style for circuit connection.

Q: Does the substitute part meet current compliance standards?

A: Yes. The AMT313Q-V meets ROHS3 compliance and maintains REACH unaffected status, equivalent to the original part's RoHS Compliant designation.

Q: What inventory status should I expect?

A: The AMT303LD-V (obsolete) has 732 pieces in stock. The AMT313Q-V (active) has 1349 pieces in stock, providing greater long-term availability assurance.
