AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 pulses per revolution with commutation output, CW 2-pole configuration, 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
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: Maintained

The AMT313Q-V qualifies as a substitute part because it maintains all critical mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution rather than the fixed 1024 PPR of the AMT303LD-V. This programmability provides equivalent or enhanced functionality for applications requiring the same physical form factor and electrical interface.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V based on matching mechanical and electrical specifications. The AMT313Q-V maintains active product status with CUI Devices, ensuring continued availability and support.

Both parts comply with RoHS requirements, with the AMT313Q-V meeting the more recent ROHS3 standard. Both parts are REACH unaffected and classified under ECCN EAR99 and HTSUS 8543.70.4500.

The primary functional difference is the programmable pulses per revolution capability of the AMT313Q-V, which can be configured to match the 1024 PPR specification of the original part. This feature provides equivalent performance with added flexibility for future design modifications.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V matches all critical mechanical and electrical parameters including mounting type, orientation, actuator type, supply voltage, and termination style. The programmable PPR feature of the AMT313Q-V can be configured to 1024 PPR to match the original specification. Physical form factor and pin configuration compatibility must be verified against your specific application requirements.

Q: What is the difference between fixed 1024 PPR and programmable PPR?

A: The AMT303LD-V provides a fixed output of 1024 pulses per revolution. The AMT313Q-V allows the PPR value to be programmed, offering flexibility to set the output to 1024 PPR or other values as needed for your application.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The AMT313Q-V meets the ROHS3 standard, which is a more recent revision. Both parts are REACH unaffected and carry the same ECCN and HTSUS classifications.

Q: What packaging is available for the substitute part?

A: The AMT313Q-V is supplied in box packaging. The original AMT303LD-V packaging specification was not provided in the available data.

Q: Is the AMT313Q-V currently in stock?

A: The AMT313Q-V has 1349 pieces listed as new original in stock. The AMT303LD-V, being obsolete, has 1061 pieces available but future availability is not guaranteed.
