Substitute Part Grouping Explanation

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

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Actuator Type: 2mm ~ 8mm Open Center (required match)
• Output Type: Commutation (required match)
• Pulses per Revolution: 96 fixed or programmable equivalent
• Termination Style: Terminal Pins or Connector variants acceptable
• Regulatory Compliance: RoHS and REACH status maintained

The substitute parts AMT313Q-V and AMT313S-V meet these core parameters. Both feature programmable pulses per revolution capability, allowing configuration to 96 PPR to match the fixed specification of the AMT303-V. Both maintain 5V supply voltage, right-angle orientation, chassis mount configuration, and commutation output type.

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 identical to the AMT303-V, providing direct mechanical and electrical compatibility with existing connector designs. This part is recommended for applications requiring minimal redesign of interface circuitry.

AMT313S-V features connector-based termination, requiring interface modification but offering standardized connector compatibility for new designs. This configuration may simplify assembly and maintenance procedures in motor-driven applications.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, exceeding the regulatory requirements of the original part. The programmable pulses per revolution feature in both alternatives provides configuration flexibility while supporting the fixed 96 PPR specification of the AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 96 PPR specification of AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 96 PPR to match the fixed specification of the original AMT303-V encoder.

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

A: The primary difference is termination style. AMT313Q-V uses terminal pins, matching the AMT303-V configuration. AMT313S-V uses a connector interface, requiring interface redesign but offering standardized connector compatibility.

Q: Are the substitute parts compatible with existing AMT303-V mounting locations?

A: Yes. Both AMT313Q-V and AMT313S-V maintain identical mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator specifications (2mm ~ 8mm Open Center), ensuring mechanical compatibility with existing motor and chassis installations.

Q: Do the substitute parts maintain the same voltage supply requirement?

A: Yes. All three encoders operate at 5V supply voltage, ensuring electrical compatibility with existing power distribution systems.

Q: What regulatory advantages do the substitute parts offer?

A: Both AMT313Q-V and AMT313S-V meet ROHS3 compliance, which exceeds the RoHS Compliant status of the original AMT303-V. Both maintain REACH unaffected status, ensuring regulatory compliance for current and future applications.

Q: Are there inventory considerations for selecting between these substitutes?

A: Both substitutes are active products with current inventory availability. AMT313Q-V has 1349 units in stock, and AMT313S-V has 1045 units in stock, providing reliable supply for production requirements.
