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 polarity, and 2-pole line driver configuration. 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

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
• Detent and Built-in Switch: No detent, no built-in switch

The AMT313Q-V meets these core compatibility criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 1024 PPR of the AMT303LD-V, this represents an enhancement in flexibility. The programmable resolution allows configuration to match the original 1024 PPR specification or other resolution requirements within the same mechanical and electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

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

• Product Status: The AMT303LD-V is obsolete, while the AMT313Q-V maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts meet RoHS and REACH requirements. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards.
• Mechanical and Electrical Compatibility: Both encoders share identical mechanical mounting, orientation, actuator specifications, and 5V supply voltage requirements.
• Functional Enhancement: The programmable resolution of the AMT313Q-V provides operational flexibility while maintaining the capability to be configured for the original 1024 PPR specification.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V. Both share identical mounting type, orientation, actuator type, supply voltage, and termination style. The programmable resolution of the AMT313Q-V must be configured to match the required pulse-per-revolution specification for your application.

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

A: The AMT303LD-V provides a fixed resolution of 1024 pulses per revolution. The AMT313Q-V allows resolution to be programmed during initialization, providing flexibility to set the encoder to 1024 PPR or other resolutions as required by your system.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with terminal pin termination. The AMT313Q-V is packaged in a box format. Both use identical terminal pin termination style for circuit board integration.

Q: Do both encoders support the same supply voltage?

A: Yes, both the AMT303LD-V and AMT313Q-V operate at 5V supply voltage.

Q: What is the significance of the commutation output with line driver?

A: The commutation output with 2-pole line driver configuration provides differential signaling suitable for noise-immune transmission in industrial motor control and positioning applications. The AMT313Q-V maintains commutation output compatibility with the original design.
