AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 250 pulses per revolution with commutation output in a right-angle chassis mount orientation. This encoder is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The AMT303-V operates at 5V supply voltage with an open center actuator design and terminal pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are selected based on strict parameter alignment across the following critical specifications:

• Encoder Type: Incremental (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)
• Output Type: Commutation (required match)
• RoHS Compliance: Maintained

The substitute parts AMT313Q-V and AMT313S-V meet all mandatory parameter requirements. Both feature programmable pulses per revolution, which provides functional equivalence to the fixed 250 PPR configuration of the AMT303-V. The key distinction between substitutes relates to termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these substitutes depends on termination requirements:

AMT313Q-V is the direct functional equivalent for applications requiring terminal pin termination, maintaining identical connection methodology to the original AMT303-V design. This part is recommended for retrofit applications where existing PCB or harness designs utilize terminal pin connections.

AMT313S-V provides the same core functionality with connector-based termination, suitable for applications where connector-based integration is preferred or required. This configuration may necessitate harness or interface modifications in existing designs.

Both substitutes feature programmable pulses per revolution, enabling configuration to the original 250 PPR specification. Both maintain 5V supply voltage, identical actuator geometry, and equivalent RoHS compliance status (ROHS3 represents an updated compliance standard). Both parts are currently in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 250 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 250 PPR to match the original encoder specification.

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

A: The termination style differs. AMT313Q-V uses terminal pins (matching the AMT303-V), while AMT313S-V uses connector termination. All other electrical and mechanical parameters are identical.

Q: Are the substitute parts compatible with existing 5V supply systems?

A: Yes. Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the original AMT303-V requirement.

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

A: Yes. Both substitutes feature right-angle orientation, chassis mount configuration, and 2mm ~ 8mm open center actuator design, matching the original encoder.

Q: What is the compliance difference between RoHS and ROHS3?

A: ROHS3 represents an updated RoHS compliance standard. Both the original AMT303-V (RoHS Compliant) and substitutes (ROHS3 Compliant) meet current regulatory requirements for restricted substances.

Q: Which substitute should be selected for new designs?

A: For new designs, either substitute is acceptable based on termination preference. AMT313Q-V is recommended if terminal pin integration is required; AMT313S-V is recommended if connector-based integration is preferred.
