Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Both are incremental encoders
• Supply Voltage: 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
• Output Type: Both provide commutation output
• Compliance: Both are RoHS compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 512 PPR. The AMT313Q-V maintains active product status, making it suitable for applications requiring the same mechanical and electrical interface characteristics.

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Selection of the AMT313Q-V is supported by:

• Product Status: The AMT313Q-V maintains active product status, ensuring continued availability and supply chain reliability
• Compliance Alignment: Both parts meet RoHS and REACH requirements; the AMT313Q-V carries ROHS3 compliance, representing current regulatory standards
• Mechanical Compatibility: Identical mounting, orientation, and actuator specifications ensure direct mechanical fit in existing designs
• Electrical Compatibility: Matching 5V supply voltage and commutation output type maintain electrical interface compatibility
• Functional Enhancement: The programmable PPR capability of the AMT313Q-V provides design flexibility while maintaining the fixed 512 PPR configuration when required

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 (chassis mount, right angle), actuator specifications (2mm ~ 8mm open center), and electrical supply requirements (5V). Terminal pin termination is consistent across both parts.

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

A: The AMT303LD-V provides a fixed 512 pulses per revolution output, while the AMT313Q-V features programmable PPR capability. Applications requiring 512 PPR can configure the AMT313Q-V accordingly.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS and REACH compliant. The AMT313Q-V carries ROHS3 certification, representing the current regulatory standard, while the AMT303LD-V carries RoHS Compliant status. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging is available for the substitute part?

A: The AMT313Q-V is supplied in box packaging, compared to the dash packaging designation of the AMT303LD-V.

Q: Why is the AMT303LD-V obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The AMT313Q-V represents the active product line continuation with enhanced programmable functionality while maintaining mechanical and electrical compatibility.
