AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 200 pulses per revolution with commutation output in counter-clockwise direction and 4-pole right-angle orientation. This component is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm to 8mm range).

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 is required.

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: Must be Incremental
• Voltage Supply: 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
• Detent and Built-in Switch: Must match (No for both)
• Environmental Compliance: RoHS and REACH status must be maintained

The substitute parts AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active-status CUI Devices encoders from the AMT31 series with programmable pulse-per-revolution capability, allowing configuration to match the 200 PPR specification of the AMT303-V. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

For Terminal Pin Termination Applications: Select AMT313Q-V. This substitute maintains identical termination style to the AMT303-V, ensuring direct compatibility with existing PCB layouts and connector designs. The AMT313Q-V is active-status with ROHS3 compliance, providing long-term supply assurance and regulatory alignment.

For Connector Termination Applications: Select AMT313S-V. This substitute provides the same core electrical and mechanical specifications as AMT303-V but with connector-based termination. The AMT313S-V is active-status with ROHS3 compliance and is suitable for applications where connector interfaces are preferred for serviceability or modularity.

Both substitutes feature programmable pulse-per-revolution configuration, enabling direct setting to 200 PPR to match the original AMT303-V specification. Both maintain full compliance with RoHS3 and REACH requirements, supporting modern regulatory standards beyond the original RoHS Compliant designation of the obsolete part.

Frequently Asked Questions (FAQ)

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

A: Both substitutes are functionally compatible with AMT303-V when configured to 200 PPR. The primary difference is termination style: AMT313Q-V uses terminal pins (direct replacement for pin-based designs), while AMT313S-V uses a connector interface (suitable for connector-based designs). Selection depends on your application's termination requirements.

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

A: The AMT313Q-V and AMT313S-V feature programmable pulse-per-revolution capability, allowing configuration to any required PPR value including 200 PPR. This flexibility provides a single substitute part solution for multiple fixed-PPR encoder applications, including the AMT303-V's 200 PPR specification.

Q: Are there any compliance differences between AMT303-V and the substitute parts?

A: The AMT303-V is RoHS Compliant, while both substitutes are ROHS3 Compliant, representing an enhanced regulatory standard. Both maintain REACH Unaffected status. The upgraded compliance of substitute parts ensures compatibility with current manufacturing and environmental regulations.

Q: What is the inventory status of these parts?

A: AMT303-V (957 Pcs) is obsolete. AMT313Q-V (1349 Pcs) and AMT313S-V (1045 Pcs) are both active-status parts with current inventory availability, supporting immediate procurement for new designs and production requirements.

Q: Are there any electrical or mechanical parameter differences that would affect circuit design?

A: All three encoders share identical electrical specifications (5V supply, incremental type, commutation output) and mechanical specifications (2mm-8mm open center actuator, right-angle orientation, chassis mount). No circuit redesign is required when substituting AMT303-V with either AMT313Q-V or AMT313S-V, provided termination style compatibility is confirmed.
