AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices with 96 pulses per revolution (PPR) and 4-pole commutation output in a right-angle orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The encoder operates at 5V supply voltage with a 2mm to 8mm open center actuator and chassis mount configuration suitable for motor applications.

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
• Output Type: Commutation

The AMT313Q-V and AMT313S-V both satisfy these core electrical and mechanical requirements. Both substitute parts feature programmable pulses per revolution, which provides operational flexibility beyond the fixed 96 PPR specification of the AMT303-V. The primary distinction between substitutes is 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, providing supply chain continuity for applications currently using the obsolete AMT303-V.

AMT313Q-V maintains terminal pin termination identical to the original AMT303-V, minimizing PCB redesign requirements. This part is suitable for direct replacement in existing designs where pin-based connections are established.

AMT313S-V provides connector-based termination, requiring interface modification but offering standardized connector compatibility for new designs or system upgrades. This configuration may simplify field serviceability.

Both substitutes feature programmable PPR capability, allowing configuration to 96 PPR to match the original specification or alternative values as system requirements permit. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to operate at 96 PPR like the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution. Configuration to 96 PPR is supported, enabling functional equivalence to the original specification.

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

A: Termination style. AMT313Q-V uses terminal pins; AMT313S-V uses a connector interface. All other electrical and mechanical parameters are identical.

Q: Is PCB modification required when replacing AMT303-V with AMT313Q-V?

A: No. AMT313Q-V maintains terminal pin termination, allowing direct substitution without PCB redesign.

Q: Does substitution require firmware or software changes?

A: PPR configuration may require system adjustment if the application depends on specific pulse count values. Both substitutes support 96 PPR programming to maintain compatibility with existing system calibration.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
