AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 400 pulses per revolution with commutation output and 20-pole right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback at 5V supply voltage.

The AMT303-V has reached obsolete product status. Identifying equivalent substitute parts ensures continued availability for maintenance, repair, and new production applications where this encoder specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

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

• Manufacturer: CUI Devices (same manufacturer ensures design consistency)
• Encoder Type: Incremental (functional classification)
• Output Type: Commutation (signal output format)
• Voltage - Supply: 5V (electrical compatibility)
• Actuator Type: 2mm ~ 8mm Open Center (mechanical interface)
• Mounting Type: Chassis Mount, Motors (installation compatibility)
• Orientation: Right Angle (physical form factor)

The substitute parts AMT313Q-V and AMT313S-V maintain these core parameters. The key difference is that substitute parts feature programmable pulses per revolution, whereas the AMT303-V is fixed at 400 PPR. Both substitutes are active products with current manufacturing status.

Engineering Selection Recommendations

AMT313Q-V is suitable for applications requiring terminal pin termination. This part maintains the same electrical and mechanical interface as the AMT303-V while offering programmable PPR configuration. Active product status ensures ongoing availability and support.

AMT313S-V is suitable for applications requiring connector-based termination. This part provides the same core functionality with the added benefit of connector interface, which may simplify integration in certain chassis mount configurations. Active product status ensures ongoing availability and support.

Both substitute parts carry ROHS3 compliance, exceeding the RoHS compliance level of the obsolete AMT303-V. Selection between AMT313Q-V and AMT313S-V depends on termination interface requirements: terminal pins versus connector.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be used as direct replacements for AMT303-V?

A: Both parts maintain the core electrical and mechanical parameters required for AMT303-V applications. The primary difference is programmable PPR configuration versus fixed 400 PPR. If the application requires exactly 400 PPR, the substitute must be programmed to this value. Termination style differs between the two substitutes.

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

A: Both parts are functionally equivalent incremental encoders with programmable PPR and commutation output. The distinction is termination style: AMT313Q-V uses terminal pins, while AMT313S-V uses connector termination. Selection depends on the mechanical interface requirements of the application.

Q: Why is the AMT303-V obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The AMT313 series represents the current active product line from CUI Devices for this encoder category.

Q: Are there any compliance differences between the obsolete and substitute parts?

A: The substitute parts carry ROHS3 compliance, which represents a more recent RoHS standard revision compared to the RoHS compliance designation of the AMT303-V. Both meet REACH unaffected status and EAR99 export classification.

Q: What parameters must match for substitution compatibility?

A: Critical matching parameters include encoder type (incremental), output type (commutation), supply voltage (5V), actuator type (2mm ~ 8mm open center), mounting type (chassis mount, motors), and orientation (right angle). Termination style and PPR configuration may differ based on application requirements.
