Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that must align for functional equivalence:

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Output Type: Commutation
• Pulses per Revolution: Fixed or Programmable capability

The AMT313Q-V and AMT313S-V both satisfy these core electrical and mechanical requirements. The primary distinction between substitutes lies in termination style and pulses per revolution configurability.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these substitutes depends on termination requirements:

AMT313Q-V maintains terminal pin termination, matching the original AMT303-V connection method. This substitute is suitable for applications requiring direct pin soldering or wire attachment without connector interfaces.

AMT313S-V provides connector-based termination, offering advantages in modularity and field replaceability. This configuration is appropriate for systems designed around connector-based encoder integration.

Both substitutes feature programmable pulses per revolution capability, enabling configuration flexibility beyond the fixed 512 PPR specification of the original part. Both maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to 512 PPR to match the original AMT303-V specification?

A: Both AMT313Q-V and AMT313S-V feature programmable pulses per revolution. Configuration to 512 PPR is within the programmable range of these substitutes, provided the application firmware or control system supports this setting.

Q: What is the primary difference between AMT313Q-V and AMT313S-V?

A: The primary difference is termination style. AMT313Q-V uses terminal pins for direct connection, while AMT313S-V uses a connector interface. Both maintain identical electrical specifications and mounting characteristics.

Q: Are the substitute parts pin-compatible with the AMT303-V?

A: AMT313Q-V maintains terminal pin termination consistent with AMT303-V. Physical pin layout and electrical signal mapping must be verified against detailed datasheets. AMT313S-V uses connector termination and requires connector-compatible interface hardware.

Q: Do the substitute parts meet current compliance standards?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original AMT303-V is RoHS compliant but carries obsolete status.

Q: What supply voltage do the substitute parts require?

A: Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the original AMT303-V specification.
