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 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

Substitute parts for the AMT303LD-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Output Type: Commutation-based output

The AMT313Q-V qualifies as a substitute because it maintains these core parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution rather than the fixed 800 PPR of the AMT303LD-V. This programmability provides design flexibility while preserving electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Selection between these parts should be based on the following factors:

For AMT303LD-V (if available from inventory):

• Fixed 800 PPR resolution is required by the application
• Existing designs are locked to this specific resolution

For AMT313Q-V (recommended for new designs and replacements):

• Active product status ensures ongoing availability and support
• ROHS3 compliance provides enhanced regulatory alignment
• Programmable PPR capability allows configuration to 800 PPR or alternative resolutions as needed
• Maintains all electrical and mechanical compatibility with the original part

Both parts share identical supply voltage, mounting configuration, orientation, and termination characteristics. The transition from fixed to programmable resolution does not impact mechanical fit or electrical interface requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts maintain identical electrical supply voltage (5V), actuator type (2mm ~ 8mm Open Center), mounting type (Chassis Mount, Motors), orientation (Right Angle), and termination style (Terminal Pins). The AMT313Q-V can be configured to 800 PPR to match the original specification.

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

A: The AMT303LD-V has a fixed 800 PPR output, while the AMT313Q-V features programmable PPR. Both use commutation-based output with 5V supply and identical mechanical interfaces.

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

A: The AMT303LD-V is no longer in active production. The AMT313Q-V represents the current active product line from CUI Devices for this encoder category.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V uses terminal pin termination, and the AMT313Q-V is supplied in Box packaging. Both maintain the same termination style for circuit board integration.

Q: Do both parts meet current compliance standards?

A: The AMT303LD-V is RoHS Compliant. The AMT313Q-V meets ROHS3 Compliant standards, representing enhanced regulatory compliance. Both are REACH Unaffected and classified as EAR99 for export purposes.

Q: Can the programmable resolution of the AMT313Q-V be set to match the original 800 PPR specification?

A: Yes. The programmable capability of the AMT313Q-V allows configuration to 800 PPR or other resolutions as required by the application.
