Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Voltage Supply: 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

The AMT313Q-V qualifies as a substitute based on matching all critical mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 250 PPR. This programmability provides design flexibility while maintaining full compatibility with the mechanical and electrical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components meet identical mechanical interface requirements and electrical supply specifications. The AMT313Q-V maintains active product status, ensuring long-term availability and supply chain continuity.

The AMT313Q-V provides programmable pulse per revolution configuration, allowing system designers to set the resolution to 250 PPR or alternative values as required. This feature does not compromise compatibility with existing mechanical mounting or electrical interfaces.

Both parts maintain equivalent compliance certifications: RoHS compliance, REACH unaffected status, and unlimited moisture sensitivity level rating. The AMT313Q-V carries ROHS3 compliance, representing current regulatory alignment.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting specifications (chassis mount, right-angle orientation, 2mm ~ 8mm open center actuator), electrical supply voltage (5V), and terminal pin termination. The physical and electrical interfaces are fully compatible.

Q: What is the primary functional difference between these two parts?

A: The AMT303LD-V provides a fixed 250 pulses per revolution output. The AMT313Q-V offers programmable pulse per revolution configuration, allowing resolution adjustment to 250 PPR or other values as needed for the application.

Q: Are there compliance or regulatory differences between the two parts?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 compliance, representing alignment with current regulatory standards. Both maintain unlimited moisture sensitivity level rating.

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

A: The AMT303LD-V has been discontinued by the manufacturer. The AMT313Q-V represents the active product line replacement, offering equivalent mechanical and electrical compatibility with enhanced programmable functionality.

Q: Are there packaging differences between the two parts?

A: The AMT303LD-V packaging information is not specified in the available data. The AMT313Q-V is supplied in box packaging. Confirm packaging requirements with your procurement or supply chain team.
