AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 500 pulses per revolution with commutation output, CCW rotation, 4-pole configuration, and integrated line driver. This component is designed for chassis mount and motor applications with right-angle orientation and terminal pin termination.

The AMT303LD-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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Mounting Type: Must support Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Output Type: Must support Commutation output with line driver capability

The AMT313Q-V meets these core substitution criteria. However, the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 500 PPR. This difference does not preclude substitution when the application can accommodate programmable resolution or when 500 PPR operation is selected within the programmable range.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is an active product from CUI Devices and serves as the primary substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply voltage, and core functional characteristics.

The AMT313Q-V provides enhanced flexibility through programmable pulse-per-revolution configuration, allowing system designers to select 500 PPR operation to match the original AMT303LD-V specification or adjust resolution as application requirements evolve.

Both parts maintain equivalent regulatory compliance: RoHS compliance (ROHS3 for the substitute represents an updated standard), REACH unaffected status, and EAR99 export classification. Moisture sensitivity levels are identical at MSL 1 (Unlimited).

Selection of the AMT313Q-V is supported by its active product status, ensuring long-term availability and supply chain stability compared to the obsolete AMT303LD-V.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V in existing designs?

A: Yes. Both encoders share identical mounting type (Chassis Mount, Motors), orientation (Right Angle), termination style (Terminal Pins), actuator type (2mm ~ 8mm Open Center), supply voltage (5V), and output type (Commutation with line driver). The primary difference is programmable versus fixed resolution.

Q: What is the key difference between these two parts?

A: The AMT303LD-V provides fixed 500 PPR output. The AMT313Q-V offers programmable PPR configuration, allowing selection of 500 PPR or alternative resolutions based on application needs.

Q: Are there compliance or certification differences?

A: Both parts are RoHS compliant, REACH unaffected, and classified as EAR99. The AMT313Q-V carries ROHS3 certification, which represents a current standard update. Both maintain MSL 1 (Unlimited) moisture sensitivity levels.

Q: Why is the AMT303LD-V listed as obsolete?

A: The AMT303LD-V has been discontinued by CUI Devices. The AMT313Q-V represents the active product line continuation with enhanced programmable functionality.

Q: Are packaging differences relevant to substitution?

A: The AMT303LD-V uses terminal pin termination in standard packaging. The AMT313Q-V is supplied in box packaging. Both use identical termination style and mounting interfaces, making packaging differences non-critical for functional substitution.

Q: Can I configure the AMT313Q-V to operate at 500 PPR?

A: The AMT313Q-V features programmable PPR capability. Configuration to 500 PPR operation is within the programmable range, enabling direct functional equivalence to the fixed 500 PPR AMT303LD-V specification.
