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:

Matching Parameters:

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center configuration
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle mounted
• Termination Style: Both use terminal pins
• Moisture Sensitivity Level: Both rated at MSL 1 (Unlimited)
• Compliance: Both are RoHS compliant and REACH unaffected

Key Difference:

• Pulses per Revolution: AMT303LD-V is fixed at 1024 PPR; AMT313Q-V features programmable PPR capability
• Product Status: AMT303LD-V is obsolete; AMT313Q-V is active

The programmable PPR feature of the AMT313Q-V provides functional equivalence with the flexibility to configure 1024 PPR output to match the original specification.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the obsolete AMT303LD-V in applications requiring incremental rotary encoding at 1024 PPR. Both components share identical mechanical mounting, electrical supply requirements, and environmental compliance certifications.

The AMT313Q-V offers the advantage of active product status, ensuring continued availability and supply chain support. The programmable PPR capability of the AMT313Q-V allows configuration to match the fixed 1024 PPR specification of the original part, maintaining functional equivalence in existing designs.

Both components meet RoHS and REACH compliance requirements and carry identical ECCN and HTSUS classifications, supporting regulatory and trade compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without design modifications?

A: The AMT313Q-V shares all critical mechanical and electrical parameters with the AMT303LD-V, including mounting type, orientation, supply voltage, and termination style. The programmable PPR feature must be configured to 1024 PPR to match the original specification. No physical modifications are required.

Q: What is the significance of the programmable PPR feature in the AMT313Q-V?

A: The AMT313Q-V allows PPR configuration through programming, whereas the AMT303LD-V is fixed at 1024 PPR. This provides flexibility for the AMT313Q-V to be used in multiple applications while maintaining compatibility with the original 1024 PPR requirement through proper configuration.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with terminal pin termination. The AMT313Q-V is packaged in a box. Both use identical terminal pin termination style for circuit integration.

Q: Do both parts meet the same compliance standards?

A: Both components are RoHS compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8543.70.4500) codes. The AMT313Q-V carries ROHS3 compliance, which supersedes the RoHS compliance of the AMT303LD-V.

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 continuation from CUI Devices for incremental rotary encoders in this category.
