AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 512 pulses per revolution with commutation output and integrated line driver functionality. This component is designed for chassis mount and motor applications with right-angle orientation and terminal pin termination.

The AMT303LD-V carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by 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 be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Output Type: Must support Commutation output

The AMT313Q-V meets all mandatory substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 512 PPR of the AMT303LD-V), this parameter does not restrict substitution eligibility when the substitute can be configured to match the original specification.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V based on the following factors:

Product Status: The AMT313Q-V carries an Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity compared to the obsolete AMT303LD-V.

Compliance Alignment: Both parts maintain equivalent environmental compliance. The AMT313Q-V achieves ROHS3 Compliant status, representing current regulatory standards, while the AMT303LD-V meets RoHS Compliant requirements. Both parts are REACH Unaffected and classified under ECCN EAR99.

Functional Compatibility: The AMT313Q-V preserves all critical mechanical and electrical parameters: 5V supply voltage, incremental encoder type, commutation output, right-angle orientation, chassis mount configuration, and terminal pin termination. The programmable pulses per revolution feature of the AMT313Q-V allows configuration to match the 512 PPR specification of the original part.

Inventory Availability: The AMT313Q-V maintains higher stock levels (1349 Pcs) compared to the AMT303LD-V (686 Pcs), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modification?

A: The AMT313Q-V meets all mandatory mechanical and electrical compatibility criteria. The programmable pulses per revolution feature must be configured to 512 PPR to match the original specification. Consult the AMT313Q-V datasheet for programming procedures and interface requirements.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Obsolete vs. Active) and pulses per revolution configuration (fixed 512 PPR vs. programmable). All other parameters—supply voltage, encoder type, output type, mounting, orientation, and termination—are equivalent.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts maintain equivalent environmental compliance classifications. The AMT313Q-V achieves current ROHS3 Compliant status, representing updated regulatory alignment. No compliance barriers exist for substitution.

Q: Does packaging differ between these parts?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in Box packaging. This difference does not affect functional compatibility or performance.

Q: What is the moisture sensitivity level for both parts?

A: Both the AMT303LD-V and AMT313Q-V carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or soldering processes.
