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 in counter-clockwise direction and 2-pole right-angle orientation. This component is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm–8mm range).

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 strict alignment with the following critical parameters:

• Encoder Type: Incremental (required match)
• Voltage Supply: 5V (required match)
• Actuator Type: 2mm–8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Termination Style: Terminal Pins or Connector (acceptable variations)
• Output Type: Commutation (required match)
• Pulses per Revolution: 400 fixed or Programmable (acceptable variation)

The substitute parts AMT313Q-V and AMT313S-V meet these criteria. Both are active-status incremental encoders with programmable pulse-per-revolution capability, allowing configuration to 400 PPR when required. Both maintain identical supply voltage, actuator type, mounting configuration, and right-angle orientation. The primary difference is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement applications. It maintains terminal pin termination identical to the AMT303-V, ensuring compatibility with existing wiring harnesses and PCB layouts. The programmable pulse-per-revolution feature allows configuration to 400 PPR, matching the original specification. Active product status ensures long-term availability and supply chain continuity. ROHS3 compliance exceeds the original RoHS requirement.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. This variant offers the same electrical and mechanical compatibility as AMT313Q-V but requires connector interface adaptation. Selection of this part depends on system design flexibility regarding termination method.

Both substitutes are active products with verified inventory levels, providing reliable alternatives to the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 400 PPR specification of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulse-per-revolution capability, allowing configuration to 400 PPR through appropriate programming or firmware settings during system integration.

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 directly. AMT313S-V uses a connector interface, requiring adapter or harness modification for integration into systems designed for the original part.

Q: Are the substitute parts physically compatible with the original mounting location?

A: Yes. Both AMT313Q-V and AMT313S-V share identical actuator type (2mm–8mm open center), mounting configuration (chassis mount, motors), and right-angle orientation as the AMT303-V, ensuring mechanical compatibility in the same mounting footprint.

Q: Do the substitute parts meet current regulatory compliance standards?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original AMT303-V was RoHS compliant; the substitutes exceed this standard.

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

A: Product obsolescence reflects manufacturer discontinuation. The active-status substitutes (AMT313Q-V and AMT313S-V) provide equivalent functionality with enhanced programmability and current regulatory compliance, making them suitable long-term alternatives.

Q: Can both substitutes operate at 5V supply voltage?

A: Yes. Both AMT313Q-V and AMT313S-V are rated for 5V supply voltage, matching the original AMT303-V requirement and ensuring compatibility with existing power distribution systems.
