Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V is identified as a substitute for the AMT303LD-V based on the following 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
• RoHS Compliance: Both meet RoHS standards
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• REACH Status: Both are REACH Unaffected
• ECCN Classification: Both classified as EAR99

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 400 PPR. The AMT313Q-V is currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the AMT303LD-V in applications requiring an incremental rotary encoder with the specified mechanical and electrical parameters. The AMT313Q-V maintains compatibility across all critical dimensions and electrical interfaces while offering the advantage of active product status and current manufacturing availability.

The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility. Applications requiring a fixed 400 PPR output can configure the AMT313Q-V accordingly during system setup.

Both parts meet equivalent compliance standards: RoHS, REACH, and EAR99 classification. 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 designs?

A: Yes. Both encoders share identical mechanical mounting, orientation, actuator type, and electrical supply voltage. The terminal pin termination style is consistent between both parts.

Q: What is the significance of programmable pulses per revolution in the AMT313Q-V?

A: The AMT313Q-V allows configuration of output resolution during system initialization. The AMT303LD-V is fixed at 400 PPR. Applications using the substitute part can be configured to output 400 PPR to match the original specification.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V packaging is listed as standard, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination suitable for chassis mount applications.

Q: How do the compliance certifications compare?

A: Both parts are RoHS compliant, REACH unaffected, and classified as EAR99. The AMT313Q-V carries ROHS3 certification, indicating compliance with the most current RoHS directive revision.

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

A: Product obsolescence typically reflects manufacturer discontinuation. The AMT313Q-V, as an active product from the same manufacturer, provides continued access to equivalent encoder functionality.
