AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 1000 pulses per revolution with commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications with a 5V supply requirement and 2mm to 8mm open center actuator compatibility.

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 determine functional compatibility:

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Moisture Sensitivity Level: 1 (Unlimited)

The AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both substitute parts maintain the same supply voltage, actuator specifications, mounting configuration, and environmental ratings. The primary distinction between substitutes lies in termination style and pulses per revolution configuration.

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 requirements:

The AMT313Q-V maintains terminal pin termination, matching the original AMT303-V connection style. This part is suitable for direct integration into existing PCB designs without connector modifications.

The AMT313S-V provides connector-based termination, requiring interface adaptation if the original design uses terminal pins. This configuration may offer advantages in applications requiring field-replaceable encoder modules.

Both substitutes carry ROHS3 compliance, exceeding the RoHS compliance of the original part. Both maintain identical supply voltage, actuator compatibility, mounting specifications, and environmental ratings. The programmable pulses per revolution feature in both substitutes provides configuration flexibility not present in the fixed 1000 PPR specification of the AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both parts share core functional parameters including encoder type, output type, supply voltage, actuator specifications, and mounting configuration. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector. Selection depends on your circuit interface requirements.

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

A: The AMT303-V is fixed at 1000 PPR. The AMT313Q-V and AMT313S-V offer programmable PPR, allowing configuration to match the 1000 PPR specification or other values as needed for your application.

Q: Are there packaging differences between these parts?

A: The AMT303-V uses terminal pin termination. The AMT313Q-V is packaged in a box with terminal pins. The AMT313S-V is packaged in a box with connector termination.

Q: Do the substitute parts meet the same environmental specifications?

A: Yes. All three parts share identical moisture sensitivity level (1 - Unlimited) and REACH status (REACH Unaffected). The substitute parts carry ROHS3 compliance, which exceeds the RoHS compliance of the original AMT303-V.

Q: Which substitute should I select for a direct replacement?

A: The AMT313Q-V is the recommended substitute for direct replacement, as it maintains terminal pin termination matching the AMT303-V. No circuit interface modifications are required.
