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 direction and 4-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 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications currently utilizing this encoder model.

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 (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)
• Manufacturer: CUI Devices (same manufacturer ecosystem)
• Output Type: Commutation (required match)
• Pulses per Revolution: Fixed or programmable configurations acceptable

The substitute parts AMT313Q-V and AMT313S-V maintain all critical mechanical and electrical parameters. Both feature programmable pulses per revolution capability, allowing configuration to match the original 500 PPR specification. Both remain in active product status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are suitable substitutes for the obsolete AMT303-V based on compliance and product status criteria:

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, providing direct mechanical and electrical compatibility with existing connector interfaces. This part is actively manufactured and holds ROHS3 compliance certification.

AMT313S-V features connector-based termination, which differs from the original terminal pin configuration. Selection of this part requires interface adaptation. This part is actively manufactured and holds ROHS3 compliance certification.

Both substitute parts support programmable pulses per revolution, enabling configuration to the original 500 PPR specification through firmware or hardware programming as applicable to the system design.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly substituted for AMT303-V without modification?

A: AMT313Q-V provides direct substitution with identical terminal pin termination. AMT313S-V requires interface adaptation due to connector-based termination versus terminal pins on the original part.

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

A: The substitute parts feature programmable PPR capability, allowing configuration to match the original 500 PPR specification. This flexibility accommodates the fixed 500 PPR configuration of the AMT303-V through appropriate system programming.

Q: Are there compliance differences between the original and substitute parts?

A: The original AMT303-V holds RoHS Compliant status. Both substitute parts hold ROHS3 Compliant status, representing an updated compliance standard. Both parts maintain REACH Unaffected status consistent with the original.

Q: What is the primary reason for substitution?

A: The AMT303-V is classified as obsolete. The AMT313Q-V and AMT313S-V are active products with current manufacturing support, ensuring long-term availability and supply chain continuity.

Q: How do the actuator specifications compare?

A: All three parts feature identical 2mm–8mm open center actuator specifications, ensuring mechanical compatibility in motor and chassis mount applications.
