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 a 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.

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)
• Output Type: Commutation output capability (required match)
• Voltage Supply: 5V operation (required match)
• Actuator Type: 2mm–8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Termination Style: Acceptable variations (Terminal Pins or Connector)
• RoHS and REACH Compliance: Must maintain regulatory status

The substitute parts AMT313Q-V and AMT313S-V share all critical electrical and mechanical parameters with the AMT303-V. Both are active products from CUI Devices with programmable pulses per revolution capability, providing functional equivalence for applications requiring the specified 400 PPR configuration.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for the AMT303-V. Both parts maintain identical termination style (Terminal Pins), electrical specifications, and mechanical form factor. The AMT313Q-V is an active product with ROHS3 compliance, providing long-term availability and regulatory alignment. The programmable pulses per revolution feature allows configuration to the required 400 PPR specification.

AMT313S-V is an alternative substitute with equivalent electrical and mechanical parameters. The primary distinction is the Connector termination style versus Terminal Pins on the original AMT303-V. This substitution is suitable for applications where connector-based termination is acceptable or preferred. The AMT313S-V is also an active product with ROHS3 compliance.

Both substitute parts satisfy the regulatory requirements (RoHS and REACH compliance) and maintain the same moisture sensitivity classification as the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares all critical electrical and mechanical parameters with the AMT303-V, including 5V supply voltage, commutation output type, right-angle orientation, and chassis mount configuration. The programmable pulses per revolution feature must be configured to 400 PPR to match the original specification. Termination style is identical (Terminal Pins), eliminating the need for connector adaptation.

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

A: Both parts are functionally equivalent substitutes for the AMT303-V. The primary difference is termination style: the AMT313Q-V uses Terminal Pins (matching the original), while the AMT313S-V uses a Connector interface. Selection depends on the application's termination requirements and circuit design.

Q: Are the substitute parts available in the same packaging as the AMT303-V?

A: The AMT303-V was supplied with dash packaging notation. The AMT313Q-V and AMT313S-V are supplied in Box packaging. Both substitute parts maintain identical mechanical dimensions and mounting interfaces required for chassis mount and motor applications.

Q: Do the substitute parts maintain the same regulatory compliance as the AMT303-V?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting or exceeding the regulatory status of the obsolete AMT303-V. Both maintain Moisture Sensitivity Level 1 (Unlimited).

Q: How is the 400 PPR specification configured on the programmable substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable pulses per revolution. Configuration to 400 PPR is performed according to the manufacturer's programming procedure for the AMT31 series. Refer to CUI Devices technical documentation for the specific configuration method applicable to your application.
