AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 200 pulses per revolution (PPR) output. This component operates at 5V supply voltage and features a right-angle orientation with chassis mount capability for motor applications. The encoder uses terminal pin termination and supports an open center actuator range of 2mm to 8mm.

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 is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is based on strict alignment of the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Moisture Sensitivity Level: Must be 1 (Unlimited)
• RoHS Compliance: Must meet or exceed RoHS requirements

The substitute parts AMT313Q-V and AMT313S-V satisfy all mandatory electrical and mechanical parameters. Both are active products from CUI Devices in the AMT31 series. The primary distinction between substitutes is the termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing support, addressing the obsolescence of the AMT303-V. Both substitutes maintain full compliance with RoHS3 and REACH requirements.

AMT313Q-V is the preferred direct substitute when terminal pin termination is required in the existing circuit design. This part preserves the original termination interface while providing programmable PPR capability.

AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred. The connector interface may simplify integration in modular system designs.

Both substitutes feature programmable pulses per revolution, allowing configuration to 200 PPR to match the original AMT303-V specification or adjustment to alternative PPR values as needed for system requirements.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be used interchangeably with AMT303-V?

A: Both parts meet the electrical and mechanical requirements for substitution. The choice depends on termination interface compatibility. AMT313Q-V uses terminal pins matching the original; AMT313S-V uses a connector. Verify your circuit board design supports the selected termination style.

Q: What is the advantage of programmable PPR in the substitute parts?

A: The AMT303-V has fixed 200 PPR output. The AMT313Q-V and AMT313S-V allow PPR configuration, enabling the same encoder to support multiple system requirements without component redesign.

Q: Are the substitute parts available in the same packaging as the original?

A: The AMT303-V packaging is listed as "-" (not specified). Both substitutes are supplied in Box packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do the substitute parts require any firmware or configuration changes?

A: The provided data does not include firmware or configuration details. Consult CUI Devices technical documentation for programming procedures specific to the AMT313Q-V and AMT313S-V.

Q: Are there any compliance differences between the main part and substitutes?

A: The AMT303-V is RoHS Compliant. Both substitutes are ROHS3 Compliant, which represents a higher standard. All three parts are REACH Unaffected and classified as EAR99 for export control purposes.
