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 500 pulses per revolution output with line driver commutation and operates at 5V supply voltage. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute for the AMT303LD-V based on the following matching parameters:

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center design
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both provide right-angle configuration
• Termination Style: Both use terminal pins
• Output Type: Both provide commutation output
• Compliance: Both are RoHS compliant and REACH unaffected

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 500 PPR. The AMT313Q-V is currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V serves as the active production substitute for the obsolete AMT303LD-V. Both encoders share identical mechanical mounting, electrical supply requirements, and output commutation characteristics. The AMT313Q-V maintains full RoHS and REACH compliance, with ROHS3 certification providing enhanced regulatory coverage. The programmable PPR capability of the AMT313Q-V allows configuration to match the fixed 500 PPR specification of the original part, ensuring functional equivalence in applications requiring this resolution.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mounting type (chassis mount, motors), orientation (right angle), actuator range (2mm ~ 8mm open center), supply voltage (5V), and termination style (terminal pins). Physical and electrical interfaces are compatible.

Q: What is the key functional difference between these two encoders?

A: The AMT303LD-V provides fixed 500 PPR output, while the AMT313Q-V features programmable PPR. The AMT313Q-V can be configured to output 500 PPR to match the original specification.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 certification, representing current regulatory standards, while the AMT303LD-V carries standard RoHS compliance.

Q: What is the packaging difference?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in box packaging.

Q: Why is the AMT303LD-V listed as obsolete?

A: The AMT303LD-V has been discontinued by CUI Devices. The AMT313Q-V represents the active production alternative with enhanced programmability and current compliance certifications.
