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
• 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)

Key Difference:

• Pulses per Revolution: AMT303LD-V provides fixed 800 PPR, while AMT313Q-V offers programmable PPR capability
• Output Type: AMT303LD-V includes line driver with 20-pole commutation; AMT313Q-V provides commutation output without specified line driver integration

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is an active product with current manufacturing status, whereas the AMT303LD-V is obsolete. Both components meet RoHS compliance requirements and share identical electrical supply voltage, mechanical mounting characteristics, and environmental ratings.

The AMT313Q-V offers programmable pulse-per-revolution configuration, providing design flexibility not available in the fixed 800 PPR specification of the AMT303LD-V. Both components maintain compatibility across core mechanical and electrical interfaces required for chassis mount and motor applications.

Selection between these parts should be based on whether fixed 800 PPR operation or programmable PPR capability aligns with system requirements, and whether the specific line driver implementation of the AMT303LD-V is functionally necessary for the application.

Frequently Asked Questions (FAQ)

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

A: Both encoders share identical mechanical mounting, electrical supply voltage, actuator type, and termination style. The primary consideration is whether the AMT313Q-V's programmable PPR capability can be configured to match the AMT303LD-V's 800 PPR specification, and whether the output type differences affect system signal processing.

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

A: The AMT313Q-V allows pulse-per-revolution configuration through programming, whereas the AMT303LD-V provides a fixed 800 PPR output. This provides flexibility for applications requiring different resolution settings without component substitution.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is specified with dash packaging, while the AMT313Q-V uses box packaging. Both maintain identical mechanical form factors and mounting interfaces.

Q: Do both parts meet current compliance standards?

A: The AMT303LD-V meets RoHS Compliant standards. The AMT313Q-V meets ROHS3 Compliant standards, representing a more recent compliance specification. Both are REACH Unaffected and carry EAR99 ECCN classification.

Q: What is the inventory status for these parts?

A: The AMT303LD-V has 916 pieces in stock as new original inventory. The AMT313Q-V has 1349 pieces in stock as new original inventory, with active product status ensuring continued availability.
