AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 400 pulses per revolution (PPR) output. This encoder features a right-angle orientation, 5V supply voltage, and chassis mount capability for motor applications. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

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
• Output Type: Commutation
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Pulses per Revolution: Fixed or programmable resolution capability

The AMT313Q-V and AMT313S-V are active product alternatives from the same manufacturer (CUI Devices) that maintain compatibility across these core electrical and mechanical parameters. Both substitutes support programmable PPR settings, enabling configuration to match the fixed 400 PPR specification of the AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives suitable for replacing the obsolete AMT303-V. Selection between these two substitutes depends on termination requirements:

• AMT313Q-V: Terminal pin termination. Maintains the same connection interface as the original AMT303-V.
• AMT313S-V: Connector termination. Requires interface adaptation if the original system uses terminal pin connections.

Both substitutes meet current RoHS3 compliance standards and maintain REACH unaffected status. The programmable PPR capability of both alternatives allows configuration to the 400 PPR specification of the original part. Active product status ensures ongoing availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V and AMT313S-V be configured to output 400 PPR like the AMT303-V?

A: Yes. Both substitutes feature programmable PPR settings, enabling configuration to match the 400 PPR output of the AMT303-V.

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

A: The termination style differs. The AMT313Q-V uses terminal pins, while the AMT313S-V uses a connector interface. Select based on your system's connection requirements.

Q: Are the mechanical mounting characteristics identical across all three encoders?

A: Yes. All three encoders share the same actuator type (2mm ~ 8mm open center), mounting type (chassis mount, motors), and orientation (right angle).

Q: Do the substitute parts meet current regulatory compliance?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.

Q: Why is the AMT303-V listed as obsolete?

A: The AMT303-V has been discontinued by the manufacturer. The AMT313 series represents the current active product line from CUI Devices for this encoder category.

Q: Are there any electrical parameter differences that would affect system compatibility?

A: No. All three encoders operate at 5V supply voltage and share identical output type specifications (commutation). The programmable PPR feature of the substitutes provides equivalent or enhanced functionality.
