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 with Line Driver capability

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 250 PPR of the AMT303LD-V, it maintains compatibility across all mechanical, electrical, and interface parameters required for direct substitution in applications where the encoder resolution can be configured to 250 PPR.

Parameter Comparison

Engineering Selection Recommendations

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

• Product Status: The AMT313Q-V maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete AMT303LD-V.
• Compliance: Both parts maintain equivalent regulatory compliance with RoHS and REACH standards. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory alignment.
• Mechanical and Electrical Compatibility: All mechanical mounting parameters, electrical supply voltage, actuator specifications, and termination methods are identical between the two parts.
• Functional Equivalence: The programmable pulses per revolution feature of the AMT313Q-V provides equivalent functionality to the fixed 250 PPR configuration of the AMT303LD-V when configured appropriately.
