AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 pulses per revolution with commutation output in a 2-pole right angle orientation. This encoder is designed for chassis mount and motor applications with a 5V supply requirement and an open center actuator range of 2mm to 8mm.

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.

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 (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)
• Detent: No (required match)
• Built-in Switch: No (required match)

The substitute parts AMT313Q-V and AMT313S-V satisfy all critical compatibility parameters. Both encoders feature programmable pulses per revolution capability, which accommodates the fixed 800 PPR specification of the AMT303-V while providing additional flexibility for alternative configurations.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product status alternatives to the obsolete AMT303-V. Both substitute parts maintain full compliance with RoHS3 and REACH requirements, meeting or exceeding the regulatory standards of the original part.

AMT313Q-V retains terminal pin termination, matching the connection style of the AMT303-V. This configuration minimizes integration changes in existing designs.

AMT313S-V features connector-based termination, which differs from the original part. Selection of this substitute requires evaluation of connector compatibility with the target application.

Both parts support programmable pulses per revolution, enabling configuration to the 800 PPR specification required by the AMT303-V application while maintaining the option for alternative PPR settings if needed.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V directly replace AMT303-V in existing applications?

A: Both parts satisfy the core functional parameters: incremental encoder type, commutation output, 5V supply, 2mm to 8mm open center actuator, chassis mount orientation, and right angle configuration. The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

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

A: The AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing configuration to 800 PPR to match the fixed specification of the AMT303-V. This programmability provides design flexibility without compromising compatibility with the original 800 PPR requirement.

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

A: The AMT303-V is RoHS Compliant. Both substitute parts are ROHS3 Compliant, representing an enhanced regulatory standard. Both parts maintain REACH Unaffected status and EAR99 ECCN classification, consistent with the original part.

Q: Which substitute part should be selected for direct integration?

A: AMT313Q-V is recommended when terminal pin termination is required to minimize integration changes. AMT313S-V is suitable for applications where connector-based termination is acceptable or preferred.
