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 12-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback at 5V supply voltage.

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this encoder specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V must satisfy the following critical parameters to ensure functional compatibility:

• Encoder Type: Incremental (required match)
• Output Type: Commutation with 12-pole configuration (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)
• Pulses per Revolution: The AMT303-V specifies 400 PPR; substitute parts with programmable PPR capability can be configured to 400 PPR output, satisfying this requirement

The identified substitutes—AMT313Q-V and AMT313S-V—meet all mandatory electrical and mechanical parameters. Both are active-status products from CUI Devices with programmable pulse-per-revolution settings, allowing configuration to match the 400 PPR specification of the obsolete AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active-status products with current manufacturing support and enhanced RoHS3 compliance, providing superior long-term availability compared to the obsolete AMT303-V.

AMT313Q-V maintains terminal pin termination, matching the connection interface of the original AMT303-V. This option minimizes integration changes and is suitable for direct board-level substitution where existing connector infrastructure is designed for terminal pins.

AMT313S-V features connector-based termination, providing a different physical interface. Selection of this variant requires evaluation of connector compatibility with existing system designs.

Both substitutes support programmable pulse-per-revolution configuration, enabling the 400 PPR output specification of the AMT303-V through firmware or hardware programming during integration.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to output 400 pulses per revolution like the AMT303-V?

A: Yes. Both substitute parts feature programmable PPR capability, allowing configuration to 400 PPR output to match the original AMT303-V specification.

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

A: The termination style differs. AMT313Q-V uses terminal pins, while AMT313S-V uses a connector interface. Selection depends on the existing system's connection requirements.

Q: Are the substitute parts compatible with 5V supply systems designed for the AMT303-V?

A: Yes. Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the electrical requirements of the original encoder.

Q: Do the substitute parts maintain the same mounting and orientation specifications?

A: Yes. Both substitutes are configured for right-angle orientation, chassis mount and motor mounting types, and feature the same 2mm ~ 8mm open center actuator type as the AMT303-V.

Q: What compliance advantages do the substitute parts offer?

A: Both AMT313Q-V and AMT313S-V meet ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment compared to the RoHS compliant AMT303-V.
