AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 512 pulses per revolution with commutation output in a right-angle orientation. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system design and maintenance applications. The encoder operates at 5V supply voltage with a chassis mount configuration suitable for motor integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Pulses per Revolution: Fixed at 512 or programmable to 512

The identified substitute parts maintain compatibility across these core electrical and mechanical parameters. The AMT313Q-V and AMT313S-V both support programmable pulse-per-revolution configuration, allowing adjustment to the 512 PPR specification of the original component. Both alternatives are active products with current manufacturing status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing support, addressing the obsolescence status of the AMT303-V. The primary distinction between the two substitutes is termination style: the AMT313Q-V uses terminal pins (matching the original AMT303-V configuration), while the AMT313S-V employs a connector-based termination.

For direct mechanical and electrical compatibility with existing PCB layouts and harnesses designed for the AMT303-V, the AMT313Q-V is the preferred substitute due to identical termination methodology. The AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred for serviceability.

Both substitutes meet or exceed the compliance requirements of the original component, with ROHS3 certification providing enhanced regulatory alignment compared to the RoHS Compliant status of the AMT303-V.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V and AMT313S-V be programmed to output exactly 512 PPR like the AMT303-V?

A: Yes. Both substitutes feature programmable pulse-per-revolution configuration, allowing adjustment to 512 PPR to match the original specification.

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

A: The termination style differs. The AMT313Q-V provides terminal pins, identical to the AMT303-V. The AMT313S-V uses a connector-based termination. All other electrical and mechanical parameters remain equivalent.

Q: Are the substitutes compatible with 5V supply systems?

A: Yes. Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the original AMT303-V requirement.

Q: Do the substitute parts maintain the same mounting configuration?

A: Yes. Both substitutes support chassis mount orientation for motor integration with right-angle configuration, identical to the AMT303-V.

Q: What is the inventory status of these substitutes?

A: AMT313Q-V: 1349 pieces in stock. AMT313S-V: 1045 pieces in stock. Both are active products with ongoing availability.
