AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 512 pulses per revolution with commutation output in a right-angle chassis mount configuration. This encoder is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The part operates at 5V supply voltage with an open center actuator design and terminal pin termination.

Key Parameters

Substitute Part Grouping Explanation

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

• 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
• Termination Style: Terminal Pins or Connector acceptable

The AMT313Q-V and AMT313S-V meet these core substitution criteria. Both parts are active products from CUI Devices with identical supply voltage, actuator specifications, mounting configuration, and orientation. The primary distinction between these substitutes is the programmable pulses per revolution capability and termination style variation.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply chain continuity for applications previously using the obsolete AMT303-V. Both substitutes maintain full compliance with ROHS3 and REACH regulations, exceeding the RoHS compliance level of the original part.

AMT313Q-V retains terminal pin termination matching the original AMT303-V configuration, minimizing integration changes in existing designs.

AMT313S-V provides connector-based termination, offering simplified mechanical assembly and potential for faster field replacement cycles.

The programmable pulses per revolution feature in both substitutes allows configuration to 512 PPR, matching the original specification, while providing flexibility for future application adjustments without component replacement.

Frequently Asked Questions (FAQ)

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

A: Both parts meet the core substitution criteria: incremental encoder type, 5V supply, identical actuator and mounting specifications, right-angle orientation, and commutation output capability. The primary difference is termination style—AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Q: What is the significance of programmable pulses per revolution in the substitute parts?

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to match the original 512 PPR specification of the AMT303-V. This eliminates the need for different part numbers across resolution requirements.

Q: Are there compliance differences between the original and substitute parts?

A: The substitute parts meet ROHS3 compliance, which supersedes the RoHS compliance of the original AMT303-V. Both maintain REACH Unaffected status. Moisture sensitivity levels remain identical at MSL 1 (Unlimited).

Q: Which substitute should be selected for direct replacement in existing assemblies?

A: AMT313Q-V is recommended for direct replacement in existing designs using terminal pin connections. AMT313S-V is suitable for new designs or applications where connector-based termination provides assembly advantages.

Q: Are inventory considerations relevant to substitution decisions?

A: Current inventory levels show AMT313Q-V (1349 pcs) and AMT313S-V (1045 pcs) in stock, both exceeding typical component availability for active products. Selection should prioritize termination style compatibility with system requirements.
