AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 192 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 system compatibility and ensure continued availability for new designs or replacement applications where the original part is no longer in production.

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
• Output Type: Commutation with Line Driver capability
• Detent and Built-in Switch: No

The AMT313Q-V meets these core compatibility criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 192 PPR of the AMT303LD-V, this parameter is configurable in the substitute part, allowing it to be set to match the original specification when required.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V based on the following factors:

• Regulatory Compliance: Both parts maintain RoHS and REACH compliance. The AMT313Q-V meets the updated ROHS3 standard, providing enhanced compliance for new designs.
• Product Availability: The AMT313Q-V is in active production status with confirmed inventory availability, whereas the AMT303LD-V is obsolete.
• Functional Equivalence: All mechanical and electrical parameters align with the original specification, including supply voltage, mounting configuration, orientation, and termination style.
• Configurable Resolution: The programmable pulses per revolution feature of the AMT313Q-V allows configuration to match the original 192 PPR specification of the AMT303LD-V.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V. The primary difference is that the AMT313Q-V requires configuration of its programmable pulses per revolution parameter to match the original 192 PPR specification. Once configured, it functions as a direct substitute.

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

A: The AMT303LD-V has a fixed 192 PPR specification set at manufacture. The AMT313Q-V allows the PPR to be programmed during setup or initialization, providing flexibility for different applications. For replacement purposes, the AMT313Q-V can be set to 192 PPR to match the original part.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V uses terminal pin termination in standard packaging. The AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination style and are compatible with the same mounting and connection methods.

Q: Does the AMT313Q-V support the same output type as the AMT303LD-V?

A: Both parts support commutation output. The AMT303LD-V specifies commutation with integrated line driver; the AMT313Q-V supports commutation output. Verify that your application's signal conditioning requirements are met by the AMT313Q-V's output characteristics.

Q: What is the inventory status of these parts?

A: The AMT303LD-V has 728 pieces in stock as new original inventory. The AMT313Q-V has 1,349 pieces in stock as new original inventory and is in active production, ensuring continued availability for future orders.
