Key Parameters

Substitute Part Grouping Explanation

Substitute components for the AMT303LD-V must satisfy the following criteria based on allowed electrical and mechanical parameters:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Output Type: Commutation with line driver capability
• RoHS Compliance: RoHS3 or equivalent

The AMT313Q-V meets these substitution criteria while offering programmable pulses per revolution, providing flexibility for applications where the fixed 1000 PPR specification of the original part may be adjusted through programming.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is an active product with ROHS3 compliance, making it suitable for new designs and replacement applications where the AMT303LD-V is no longer available. Both components share identical mechanical mounting, electrical supply requirements, and output interface specifications.

The primary distinction is the programmable pulses per revolution feature of the AMT313Q-V, which can be configured to match the 1000 PPR specification of the original part through appropriate programming. This flexibility supports multiple application requirements within a single component design.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares identical mechanical mounting, supply voltage, actuator type, and termination specifications with the AMT303LD-V. The programmable pulses per revolution feature must be configured to 1000 PPR to match the original part's output characteristics.

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

A: The AMT303LD-V provides a fixed 1000 PPR output. The AMT313Q-V allows pulses per revolution to be set through programming, enabling configuration flexibility for different application requirements.

Q: Are there packaging differences between these components?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in a box. Both use identical terminal pin termination and are suitable for the same mounting applications.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS compliant and REACH unaffected. The AMT303LD-V carries RoHS Compliant status, while the AMT313Q-V carries ROHS3 Compliant status. Both are classified under ECCN EAR99 and HTSUS 8543.70.4500.

Q: Why is the AMT303LD-V classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The active status of the AMT313Q-V provides a direct path for continued component availability and system support.
