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

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 192 PPR of the AMT303LD-V), it maintains compatibility across all mechanical, electrical, and interface parameters. The programmable capability of the substitute part provides additional flexibility without compromising the required functional parameters.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is a direct substitute for the AMT303LD-V based on the following engineering criteria:

Compliance & Regulatory: Both parts maintain equivalent RoHS and REACH compliance status. The AMT313Q-V achieves ROHS3 compliance, which represents an advancement over the RoHS Compliant status of the original part. Both parts share identical ECCN and HTSUS classifications.

Product Availability: The AMT303LD-V is obsolete, while the AMT313Q-V is active in production. This status difference makes the AMT313Q-V the appropriate selection for new designs and replacement applications.

Functional Equivalence: All mechanical, electrical, and interface parameters align between the two parts. The programmable pulses per revolution feature of the AMT313Q-V provides operational flexibility while maintaining the capability to be configured to match the original 192 PPR specification.

Inventory Status: The AMT313Q-V is available in higher quantities (1349 pcs) compared to the AMT303LD-V (742 pcs), supporting supply chain continuity.
