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 a right-angle chassis mount orientation. This encoder operates at 5V supply voltage and features an open center actuator design suitable for motor and chassis mounting applications.

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
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Manufacturer: CUI Devices (same product family)

The substitute parts AMT313Q-V and AMT313S-V maintain these core electrical and mechanical parameters. Both substitutes feature programmable pulses per revolution capability, which provides operational flexibility beyond the fixed 500 PPR specification of the AMT303-V. The primary distinction between substitutes lies in 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 product status alternatives to the obsolete AMT303-V, ensuring long-term supply chain viability and continued manufacturer support.

AMT313Q-V is the preferred substitute when direct termination compatibility is required, as it maintains terminal pin termination identical to the AMT303-V. This substitute is suitable for applications where existing connector interfaces or PCB layouts are designed for pin termination.

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

Both substitutes comply with ROHS3 standards, exceeding the RoHS compliance of the original part. Both maintain REACH unaffected status and EAR99 export classification consistent with the AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both substitutes maintain the same electrical supply voltage (5V), encoder type (incremental), output type (commutation), actuator design (2mm ~ 8mm open center), mounting configuration (chassis mount, motors), and orientation (right angle). The primary difference is termination style: AMT313Q-V uses terminal pins matching the original, while AMT313S-V uses a connector. Selection depends on your existing interface requirements.

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

A: The AMT303-V operates at a fixed 500 PPR specification. The AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing configuration flexibility for different resolution requirements within a single hardware platform. If your application requires 500 PPR, both substitutes can be programmed to this specification.

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

A: The substitute parts (AMT313Q-V and AMT313S-V) comply with ROHS3 standards, which represent a more current regulatory requirement than the RoHS compliance of the AMT303-V. Both substitutes maintain REACH unaffected status and EAR99 export classification consistent with the original part.

Q: Which substitute should I select for new designs?

A: For new designs, either AMT313Q-V or AMT313S-V is appropriate based on termination interface requirements. AMT313Q-V is recommended if terminal pin integration is preferred; AMT313S-V is recommended if connector-based integration is preferred. Both are active products with full manufacturer support.

Q: Is the connector type specified for AMT313S-V?

A: The connector termination style is specified for AMT313S-V. Refer to the CUI Devices product datasheet for specific connector type and pinout details.
