Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

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

The AMT313Q-V and AMT313S-V meet all critical electrical and mechanical parameters. Both are active products from CUI Devices' AMT31 series. The primary distinction between substitutes is termination style: AMT313Q-V uses Terminal Pins (matching the original), while AMT313S-V uses Connector termination.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement of the AMT303-V. This part maintains identical termination style (Terminal Pins), electrical specifications, and mechanical configuration. The AMT313Q-V carries active product status with ROHS3 compliance, providing superior regulatory standing compared to the obsolete original part.

AMT313S-V serves as an alternative substitute when connector-based termination is acceptable for the application. This part meets all electrical and mechanical requirements but requires interface modification due to Connector termination versus Terminal Pins. The AMT313S-V also carries active product status with ROHS3 compliance.

Both substitutes are manufactured by CUI Devices and maintain full compatibility with the original part's functional specifications, supply voltage, and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V directly replace AMT303-V without circuit modification?

A: Yes. The AMT313Q-V maintains identical electrical specifications (5V supply, programmable commutation output), mechanical configuration (right-angle orientation, 2mm ~ 8mm open center actuator), and termination style (Terminal Pins). No circuit modification is required.

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

A: Both parts are electrically and mechanically equivalent. The primary difference is termination style: AMT313Q-V uses Terminal Pins, while AMT313S-V uses Connector termination. Select AMT313Q-V for direct pin-compatible replacement or AMT313S-V if connector-based interface is preferred.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant, exceeding the RoHS Compliant status of the original AMT303-V.

Q: What is the product status difference between the original and substitutes?

A: The AMT303-V is obsolete, while both AMT313Q-V and AMT313S-V are active products. Active status ensures continued manufacturing, availability, and technical support from CUI Devices.

Q: Are the substitute parts suitable for motor and chassis mount applications?

A: Yes. Both substitutes are rated for Chassis Mount and Motors mounting types, matching the original part's application scope.

Q: Do the substitute parts maintain the same programmable pulses per revolution capability?

A: Yes. All three parts feature programmable pulses per revolution output, maintaining functional equivalence for commutation applications.
