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
• Pulses per Revolution: Must be 1024 or programmable to 1024

The AMT313Q-V qualifies as a substitute because it maintains compatibility across all critical mechanical and electrical parameters. The key distinction is that the AMT313Q-V features programmable pulses per revolution, allowing configuration to 1024 PPR to match the fixed specification of the AMT303LD-V.

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Product Status: The AMT303LD-V is obsolete, while the AMT313Q-V maintains active product status with current manufacturing support and availability.

Compliance & Certifications: Both parts maintain equivalent environmental compliance. The AMT303LD-V is RoHS Compliant; the AMT313Q-V is ROHS3 Compliant, representing an enhanced compliance standard. Both are REACH Unaffected and classified under ECCN EAR99.

Functional Compatibility: The AMT313Q-V provides programmable pulses per revolution, enabling configuration to the 1024 PPR specification of the AMT303LD-V. All mechanical parameters—actuator type, mounting configuration, orientation, and termination—are identical between the two parts.

Inventory & Availability: The AMT313Q-V has confirmed inventory of 1349 pieces in stock, ensuring supply continuity for production and replacement applications.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V. The programmable pulses per revolution feature must be configured to 1024 PPR to match the fixed specification of the original part. No physical modifications are required.

Q: What is the difference between fixed and programmable pulses per revolution?

A: The AMT303LD-V has a fixed output of 1024 PPR. The AMT313Q-V allows pulses per revolution to be programmed during initialization or configuration, providing flexibility for different application requirements while maintaining the ability to operate at 1024 PPR.

Q: Are the packaging specifications compatible?

A: The AMT303LD-V is specified with dash packaging; the AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination and mounting configurations. Packaging differences do not affect functional compatibility.

Q: What compliance certifications apply to both parts?

A: Both the AMT303LD-V and AMT313Q-V are RoHS compliant, REACH Unaffected, and classified under ECCN EAR99. The AMT313Q-V carries the enhanced ROHS3 certification standard.

Q: Is the AMT313Q-V suitable for motor and chassis mount applications?

A: Yes. Both parts are specified for Chassis Mount and Motors applications with identical right-angle orientation and 2mm ~ 8mm open center actuator compatibility.
