AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured with 512 pulses per revolution and 20-pole commutation output in a right-angle orientation. This component is classified as obsolete, necessitating identification of active substitute parts that maintain functional and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303-V is determined by strict alignment of the following critical parameters:

• Encoder Type: Must be Incremental
• Output Type: Must support Commutation output
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Detent: Must be No
• Built-in Switch: Must be No
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The substitute parts identified—AMT313Q-V and AMT313S-V—satisfy all mechanical and electrical compatibility requirements. Both are active products from CUI Devices with programmable pulses per revolution capability, providing functional equivalence to the fixed 512 PPR configuration of the AMT303-V.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing long-term supply assurance compared to the obsolete AMT303-V. Both substitute parts maintain full compliance with RoHS3 and REACH regulations, meeting modern environmental and safety standards.

The primary distinction between the two substitutes is termination style: AMT313Q-V retains terminal pins matching the original AMT303-V configuration, while AMT313S-V uses a connector termination. Selection between these substitutes should be based on existing PCB or harness design requirements.

The programmable pulses per revolution feature of both substitutes provides design flexibility, allowing configuration to 512 PPR to match the original specification or alternative values as application requirements permit.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy all critical mechanical and electrical parameters. AMT313Q-V is the direct pin-compatible substitute. AMT313S-V requires connector accommodation but is functionally equivalent.

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

A: The primary difference is termination style. AMT313Q-V uses terminal pins; AMT313S-V uses a connector. Both maintain identical encoder specifications, supply voltage, mounting type, and orientation.

Q: Are the substitute parts RoHS compliant?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant, exceeding the RoHS compliance level of the obsolete AMT303-V.

Q: Can the programmable PPR feature of the substitutes be configured to match the original 512 PPR specification?

A: Yes. Both substitute parts support programmable configuration to 512 pulses per revolution, matching the original AMT303-V specification.

Q: What is the inventory status of these substitute parts?

A: AMT313Q-V has 1349 units in stock; AMT313S-V has 1045 units in stock, both as new original components.
