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 96 PPR. The AMT313Q-V also carries an active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical electrical supply requirements (5V), mechanical mounting specifications (chassis mount, right-angle orientation), and environmental compliance certifications (RoHS, REACH, MSL 1).

The AMT313Q-V maintains active product status with CUI Devices, ensuring component availability and ongoing technical support. Both parts meet equivalent regulatory and compliance standards, with the AMT313Q-V meeting the more recent ROHS3 specification.

The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility. Applications requiring the fixed 96 PPR specification of the original part can configure the AMT313Q-V accordingly during implementation.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares all critical mechanical and electrical parameters with the AMT303LD-V, including 5V supply voltage, 2mm ~ 8mm open center actuator, right-angle orientation, and terminal pin termination. Both components are rated for chassis mount and motor applications. The primary consideration is configuring the AMT313Q-V's programmable pulses per revolution to match the original 96 PPR specification if required by the application.

Q: What is the significance of the programmable pulses per revolution feature?

A: The AMT313Q-V offers programmable PPR configuration, whereas the AMT303LD-V is fixed at 96 PPR. This feature allows the substitute part to be configured for the original specification or adapted to alternative resolution requirements within the same mechanical and electrical envelope.

Q: Are there compliance or certification differences between these parts?

A: Both parts are RoHS compliant, REACH unaffected, and classified as EAR99. The AMT313Q-V meets the more recent ROHS3 specification, while the AMT303LD-V meets the original RoHS standard. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging difference?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in box packaging. This does not affect component functionality or electrical characteristics.

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

A: The AMT303LD-V carries obsolete product status, indicating it is no longer in active production. The AMT313Q-V is the active equivalent offering from CUI Devices, providing continued availability and support for applications requiring incremental rotary encoder functionality with commutation output.
