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 orientation. This component is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Manufacturer: CUI Devices (same product family)

The substitute parts AMT313Q-V and AMT313S-V maintain these core electrical and mechanical specifications. Both alternatives feature programmable pulses per revolution, which provides operational flexibility beyond the fixed 500 PPR configuration of the AMT303-V. The primary distinction between substitutes lies in termination style: 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 products with current manufacturing status, providing supply chain continuity for applications currently using the obsolete AMT303-V.

AMT313Q-V is the preferred direct substitute when terminal pin termination is required. This component maintains identical electrical interface characteristics and mounting specifications as the original AMT303-V. The programmable pulses per revolution feature allows configuration to 500 PPR to match legacy system requirements.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. This variant offers the same electrical performance and mechanical compatibility but requires interface adaptation at the termination point.

Both substitutes meet current RoHS3 compliance standards and maintain REACH unaffected status, satisfying modern regulatory requirements for component procurement and system deployment.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical supply voltage (5V), actuator type (2mm ~ 8mm open center), mounting configuration (chassis mount, right angle), and terminal pin termination. The AMT313Q-V must be programmed to 500 PPR to match the original fixed configuration.

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

A: The termination interface differs. AMT313Q-V uses terminal pins, matching the AMT303-V original design. AMT313S-V uses a connector interface, requiring mechanical and electrical interface adaptation.

Q: Why is the AMT303-V obsolete?

A: The product has been discontinued by the manufacturer. The AMT313 series represents the current generation of CUI Devices incremental rotary encoders with enhanced programmability.

Q: Are the substitute parts compatible with existing PCB designs?

A: AMT313Q-V is compatible with designs using terminal pin connections. AMT313S-V requires connector accommodation on the PCB or external adapter implementation.

Q: What compliance certifications apply to the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement.

Q: Can the programmable PPR feature be configured to values other than 500?

A: Yes. The AMT313Q-V and AMT313S-V feature programmable pulses per revolution, allowing configuration flexibility beyond the fixed 500 PPR specification of the original AMT303-V.
