AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 250 pulses per revolution with commutation output, CCW rotation, 8-pole configuration, and integrated line driver. The encoder 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 applications currently utilizing this encoder model.

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 operation
• Supply Voltage: 5V operation
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Output Configuration: Commutation output with line driver capability

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across all critical mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 250 PPR. This programmability provides additional flexibility for applications that can accommodate variable resolution settings.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both parts maintain identical compliance certifications (RoHS, REACH, ECCN, HTSUS) and share the same regulatory classification. The AMT313Q-V carries active product status, ensuring ongoing availability and supply chain continuity.

The AMT313Q-V's programmable pulses per revolution feature does not compromise compatibility with applications designed for the fixed 250 PPR configuration of the AMT303LD-V. The programmable resolution can be configured to match the original 250 PPR specification when required.

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 methods. The AMT313Q-V's programmable resolution can be set to 250 PPR to match the original part's fixed configuration.

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

A: The AMT303LD-V has a fixed 250 PPR resolution, while the AMT313Q-V offers programmable pulses per revolution. This provides the AMT313Q-V with greater flexibility for applications requiring variable resolution settings.

Q: Are there any compliance or regulatory differences?

A: Both parts are RoHS compliant, REACH unaffected, and classified under the same ECCN and HTSUS codes. The AMT313Q-V meets ROHS3 compliance, which supersedes the RoHS compliance of the AMT303LD-V.

Q: What packaging is available for the AMT313Q-V?

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

Q: Is the AMT313Q-V currently in stock?

A: Yes. The AMT313Q-V has active product status with 1,349 pieces available in new original stock, compared to the obsolete AMT303LD-V with 813 pieces remaining in inventory.
