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 required
• Supply Voltage: 5V operation mandatory
• Mounting Type: Chassis mount and motor applications
• Orientation: Right angle configuration
• Termination Style: Terminal pins
• Actuator Type: 2mm ~ 8mm open center compatibility
• Output Configuration: Commutation output with line driver capability

The AMT313Q-V meets these core substitution criteria while offering programmable pulses per revolution, providing flexibility for applications where the fixed 200 PPR specification of the AMT303LD-V may be adjusted through programming.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V based on functional parameter alignment and active product status. The substitute maintains identical mechanical mounting, electrical supply requirements, and output configuration compatibility.

The AMT313Q-V offers ROHS3 compliance, exceeding the RoHS compliance level of the original part, ensuring compatibility with current regulatory requirements. Active product status guarantees continued availability and supply chain reliability.

The programmable pulses per revolution feature of the AMT313Q-V provides operational flexibility. Applications requiring the fixed 200 PPR specification of the AMT303LD-V can configure the substitute accordingly through programming, eliminating the need for hardware redesign.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V in existing designs?

A: Yes. Both encoders share identical mechanical mounting (chassis mount, right angle), electrical supply (5V), actuator compatibility (2mm ~ 8mm open center), and termination style (terminal pins). The substitute maintains commutation output configuration required for the application.

Q: What is the primary difference between these two encoders?

A: The AMT303LD-V provides a fixed 200 pulses per revolution output. The AMT313Q-V features programmable pulses per revolution, allowing configuration to match the original 200 PPR specification or other values as required by the application.

Q: Does the programmable feature of the AMT313Q-V require additional components or firmware changes?

A: Programming capability is inherent to the AMT313Q-V design. Configuration is performed through the encoder's programming interface. Existing system firmware compatible with 200 PPR commutation output will function with the substitute when configured to this specification.

Q: Are there packaging differences between the main part and substitute?

A: The AMT303LD-V is packaged as a single unit. The AMT313Q-V is supplied in box packaging. Both maintain identical mechanical form factor and terminal pin configuration for direct substitution.

Q: What is the compliance status of the substitute part?

A: The AMT313Q-V holds ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. This represents an improvement over the RoHS compliance of the original AMT303LD-V.

Q: Is the AMT313Q-V currently available?

A: Yes. The AMT313Q-V maintains active product status with documented inventory availability, ensuring reliable supply for replacement and new design applications.
