AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 500 pulses per revolution with commutation output in counter-clockwise direction and 8-pole right-angle orientation. This component is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm to 8mm range).

The AMT303-V carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for new designs or replacement applications.

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
• Detent: No
• Built-in Switch: No
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS and REACH Compliance Status

The substitute parts AMT313Q-V and AMT313S-V maintain these core parameters. The primary difference is that substitute parts feature programmable pulses per revolution rather than fixed 500 PPR, and both are in active product status. Termination style differs between substitutes: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

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 interface requirements:

AMT313Q-V maintains terminal pin termination, providing direct compatibility with existing wiring harnesses designed for the AMT303-V. This part carries ROHS3 compliance and is available in box packaging with 1349 units in stock.

AMT313S-V features connector-based termination, requiring interface adaptation if the original design uses terminal pins. This part also carries ROHS3 compliance and is available in box packaging with 1045 units in stock.

Both substitutes support programmable pulses per revolution, allowing configuration to match the original 500 PPR specification or alternative values as required by system design. Both maintain identical supply voltage, actuator type, mounting configuration, and compliance certifications.

Frequently Asked Questions (FAQ)

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

A: Both parts maintain the core electrical and mechanical parameters required for substitution: incremental encoder type, 5V supply, 2mm to 8mm open center actuator, right-angle orientation, and chassis mount configuration. The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Selection depends on your wiring interface requirements.

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

A: The AMT303-V is fixed at 500 PPR. The AMT313Q-V and AMT313S-V offer programmable PPR, allowing configuration to 500 PPR to match the original specification or to alternative values if your system design permits. This flexibility provides additional design options beyond direct replacement.

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

A: The AMT303-V carries RoHS Compliant status, while both substitutes carry ROHS3 Compliant status. Both maintain REACH Unaffected status. ROHS3 represents an updated compliance standard. Both substitutes meet current regulatory requirements for electronic components.

Q: What packaging is available for the substitute parts?

A: Both AMT313Q-V and AMT313S-V are supplied in box packaging. The AMT303-V packaging information was not specified in the original documentation.

Q: Which substitute should I select if I need to minimize design changes?

A: AMT313Q-V is the recommended choice if your existing design uses terminal pin connections, as it maintains the same termination style as the AMT303-V. No interface modifications are required.
