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-based output with line driver capability

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across all mechanical and electrical interface parameters. The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 1024 PPR. This programmability provides additional flexibility for applications that can accommodate variable resolution settings.
