Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute for the AMT303LD-V based on the following alignment of critical parameters:

Matching Parameters:

• Encoder Type: Both are incremental encoders
• Voltage Supply: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center design
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configuration
• Termination Style: Both use terminal pins
• Compliance: Both are RoHS compliant and REACH unaffected

Functional Difference: The AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 512 PPR. This programmability provides design flexibility for the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Selection should be based on the following factors:

Product Status: The AMT313Q-V maintains active product status with current manufacturing support, whereas the AMT303LD-V is obsolete. This ensures long-term availability and supply chain continuity.

Compliance Certifications: Both parts maintain RoHS compliance and REACH unaffected status, satisfying regulatory requirements for electronic component applications.

Programmability Advantage: The AMT313Q-V offers programmable pulse per revolution configuration, enabling system flexibility that the fixed 512 PPR design of the AMT303LD-V does not provide.

Mechanical and Electrical Compatibility: Matching supply voltage (5V), actuator type (2mm ~ 8mm open center), mounting configuration (chassis mount, motors), orientation (right angle), and termination style (terminal pins) ensure direct functional replacement in existing mechanical and electrical assemblies.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical supply voltage, actuator type, mounting configuration, orientation, and termination style. The mechanical and electrical interfaces are compatible for direct substitution.

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

A: The AMT303LD-V provides a fixed 512 pulses per revolution output, while the AMT313Q-V features programmable pulse per revolution capability. This allows the substitute part to be configured for different resolution requirements.

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

A: Product obsolescence is determined by the manufacturer. The AMT313Q-V, as an active product with programmable functionality, serves as the current generation replacement.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with dash packaging, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination.

Q: Do both parts meet the same regulatory standards?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 compliance, representing the current RoHS standard revision.

Q: What inventory status should I expect?

A: The AMT303LD-V has 1078 pieces in stock as new original inventory. The AMT313Q-V has 1349 pieces in stock as new original inventory, providing greater availability for new orders.
