AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This component is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by alignment across the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must support Chassis Mount, Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Pulses per Revolution: The AMT303-V specifies 800 PPR; substitute parts with programmable PPR capability can be configured to match this requirement

The substitute parts AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active-status incremental encoders from the AMT31 series with programmable pulse-per-revolution settings, allowing configuration to the 800 PPR specification of the original part. 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-status 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 integration changes in existing PCB designs and wiring harnesses. This part is the preferred direct replacement when connector interface modifications are not feasible.

AMT313S-V provides connector-based termination, offering advantages in modular system designs and applications requiring frequent component replacement or reconfiguration. Selection of this variant requires accommodation of the connector interface in the mechanical and electrical design.

Both substitute parts carry ROHS3 compliance, exceeding the RoHS compliance of the original part, and maintain REACH unaffected status. The programmable PPR capability of both substitutes requires configuration to 800 PPR to match the original specification; this configuration is performed during manufacturing or through firmware programming depending on the specific implementation.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly interchanged with AMT303-V?

A: Both parts meet the core electrical and mechanical compatibility requirements. AMT313Q-V is the closer match due to identical terminal pin termination. AMT313S-V requires connector interface accommodation. Both require PPR configuration to 800 to match the original specification.

Q: What is the difference between terminal pin and connector termination?

A: AMT313Q-V uses terminal pins for direct soldering or wire connection to PCBs or harnesses. AMT313S-V uses a connector interface, requiring a mating connector assembly. Terminal pin termination (AMT313Q-V) typically involves fewer integration steps for existing designs.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant, meeting current regulatory requirements. The original AMT303-V was RoHS compliant under earlier standards.

Q: How is the 800 PPR specification achieved on programmable parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR settings. Configuration to 800 PPR is performed during manufacturing or through the supplier's programming service. Verify PPR configuration with the supplier prior to component delivery.

Q: What is the inventory status of substitute parts?

A: AMT313Q-V has 1349 units in stock. AMT313S-V has 1045 units in stock. Both are active products with ongoing manufacturing support.
