Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that determine functional and mechanical interchangeability:

Primary Compatibility Criteria:

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Detent: No
• Built-in Switch: No
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99

Variable Parameter:

• Pulses per Revolution: The AMT303-V specifies 512 PPR as a fixed configuration. Substitute parts with programmable PPR capability maintain compatibility when configured to 512 PPR operation.

Secondary Consideration:

• Termination Style: The primary part uses Terminal Pins. Substitute parts may employ alternative termination styles (Terminal Pins or Connector) while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for the AMT303-V. Both parts maintain identical termination style (Terminal Pins), identical actuator and mounting specifications, and equivalent electrical characteristics. The AMT313Q-V features programmable pulses per revolution, which can be configured to match the 512 PPR specification of the original part. The AMT313Q-V holds active product status and meets ROHS3 compliance, providing long-term availability and regulatory alignment for new designs and production continuity.

AMT313S-V is an alternative substitute with identical functional and mechanical parameters to the AMT313Q-V, with the exception of termination style. The AMT313S-V employs a Connector termination interface rather than Terminal Pins. This part is suitable for applications where connector-based termination is preferred or required by system architecture. The AMT313S-V also maintains active product status and ROHS3 compliance.

Both substitute parts satisfy all critical compatibility criteria and provide regulatory compliance advantages over the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V and AMT313S-V be used interchangeably with the AMT303-V?

A: Both parts are functionally compatible with the AMT303-V when configured for 512 PPR operation. The primary difference between them is termination style: AMT313Q-V uses Terminal Pins (matching the original), while AMT313S-V uses a Connector interface. Selection depends on the application's termination requirements.

Q: What is the significance of programmable pulses per revolution in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing configuration to 512 PPR to match the fixed specification of the AMT303-V. This flexibility provides additional design options for future applications while maintaining compatibility with existing 512 PPR requirements.

Q: Are there compliance differences between the original part and substitutes?

A: The AMT303-V is RoHS Compliant, while both substitute parts meet the more recent ROHS3 Compliant standard. Both maintain REACH Unaffected status and identical ECCN and HTSUS classifications. The ROHS3 compliance of substitute parts ensures alignment with current regulatory requirements.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring Terminal Pins termination, select AMT313Q-V. For applications requiring Connector termination, select AMT313S-V. Both parts offer active product status, ensuring long-term availability and supply chain stability.

Q: Are the mechanical mounting and actuator specifications identical across all three parts?

A: Yes. All three parts share identical Chassis Mount/Motors mounting type, Right Angle orientation, and 2mm ~ 8mm Open Center actuator type, ensuring mechanical interchangeability in existing installations.
