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 1000 pulses per revolution with commutation output, CW, 2-pole configuration, and integrated line driver functionality. The product is classified as 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
• Voltage Supply: 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 Configuration: Must support commutation output

The AMT313Q-V qualifies as a substitute based on matching all mandatory parameters. While the AMT313Q-V features programmable pulses per revolution (versus fixed 1000 PPR on the AMT303LD-V), this represents an enhancement in flexibility rather than a functional incompatibility, as the programmable encoder can be configured to operate at 1000 PPR when required.

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maintains active product status, ensuring continued availability and manufacturer support, whereas the AMT303LD-V is obsolete.
• Compliance Alignment: Both components meet RoHS and REACH requirements. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards.
• Functional Compatibility: All critical mechanical and electrical parameters align between the two encoders, including supply voltage, mounting configuration, orientation, and termination style.
• Enhanced Capability: The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility while maintaining backward compatibility when configured to 1000 PPR operation.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting, electrical supply requirements, actuator specifications, and termination styles. The AMT313Q-V can be configured to operate at 1000 PPR, matching the fixed output of the AMT303LD-V.

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

A: The AMT303LD-V provides fixed 1000 PPR output, while the AMT313Q-V offers programmable PPR configuration. The AMT313Q-V also maintains active product status compared to the obsolete AMT303LD-V.

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

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

Q: Do both encoders meet current regulatory compliance standards?

A: Yes. Both components are RoHS compliant and REACH unaffected. The AMT313Q-V achieves ROHS3 compliance, representing the current regulatory standard.

Q: What supply voltage is required for operation?

A: Both the AMT303LD-V and AMT313Q-V operate at 5V supply voltage.

Q: Are there any differences in moisture sensitivity or environmental ratings?

A: No. Both encoders share identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
