Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303LD-V is based on the following critical parameters that must align for functional compatibility:

• Encoder Type: Incremental operation
• Supply Voltage: 5V operation
• Actuator Type: 2mm ~ 8mm Open Center compatibility
• Mounting Type: Chassis Mount, Motors capability
• Orientation: Right Angle configuration
• Termination Style: Terminal Pins interface
• Output Characteristics: Commutation-based output with line driver functionality

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than fixed 1024 PPR, it can be configured to operate at 1024 PPR, maintaining functional equivalence in applications requiring this specific resolution.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the primary substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and core functional characteristics. The AMT313Q-V holds active product status, ensuring ongoing availability and support.

The AMT313Q-V provides enhanced flexibility through programmable pulse-per-revolution configuration, allowing 1024 PPR operation when required. Both components maintain equivalent RoHS and REACH compliance profiles, with the AMT313Q-V meeting the more recent ROHS3 standard.

Selection of the AMT313Q-V eliminates obsolescence risk while maintaining full mechanical and electrical compatibility with existing designs utilizing the AMT303LD-V.
