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 integrated line driver functionality. 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 design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: 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 Type: Must support Commutation output
• RoHS Compliance: Must meet RoHS requirements

The AMT313Q-V qualifies as a substitute part because it matches all mandatory mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 800 PPR. This difference does not prevent substitution when the application can accommodate programmable resolution or when 800 PPR operation is selected within the programmable range.

Engineering Selection Recommendations

The AMT313Q-V is an active product with ROHS3 compliance, making it suitable for new designs and production environments where component availability and regulatory compliance are required. The AMT303LD-V, being obsolete, presents supply chain risk for ongoing production.

Selection between these parts should be based on the following criteria:

• Fixed Resolution Requirement: If the application requires exactly 800 PPR and cannot accommodate programmable resolution, the AMT313Q-V must be configured to operate at 800 PPR during setup.
• Supply Chain Continuity: The AMT313Q-V offers superior long-term availability as an active product.
• Regulatory Compliance: Both parts meet RoHS requirements; the AMT313Q-V meets the more recent ROHS3 standard.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modification?

A: Yes, provided the AMT313Q-V is programmed to operate at 800 PPR. All mechanical, electrical, and interface parameters are compatible. The programmable nature of the AMT313Q-V does not prevent direct substitution.

Q: What is the difference between fixed and programmable pulses per revolution?

A: The AMT303LD-V provides a fixed output of 800 PPR. The AMT313Q-V allows the PPR value to be configured during initialization. Once configured, the AMT313Q-V operates at the selected resolution.

Q: Are there any packaging differences between these parts?

A: The AMT303LD-V uses terminal pin termination in standard packaging. The AMT313Q-V is supplied in a box. Both use identical terminal pin termination and mounting interfaces.

Q: Is the line driver output compatible between these parts?

A: The AMT303LD-V explicitly includes integrated line driver functionality. The AMT313Q-V provides commutation output. Verify that your application can operate with the AMT313Q-V's output characteristics before substitution.

Q: What is the inventory status for these parts?

A: The AMT303LD-V has 1010 pieces in stock as new original inventory. The AMT313Q-V has 1349 pieces in stock as new original inventory. The AMT313Q-V offers better long-term availability due to its active product status.
