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 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 where this encoder specification remains functionally required.

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 with Line Driver capability

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 512 PPR of the AMT303LD-V, it can be configured to operate at 512 PPR, making it functionally equivalent for applications requiring this specific resolution.

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 maintains active product status with CUI Devices, ensuring ongoing availability and supply chain continuity compared to the obsolete AMT303LD-V.

Compliance Alignment: Both parts maintain equivalent environmental compliance profiles. The AMT303LD-V is RoHS Compliant, while the AMT313Q-V is ROHS3 Compliant, representing an advancement in regulatory compliance standards. Both parts are REACH Unaffected and classified under ECCN EAR99.

Functional Equivalence: The AMT313Q-V provides programmable pulse per revolution configuration, allowing it to be set to 512 PPR to match the fixed specification of the AMT303LD-V. All other critical parameters—supply voltage, actuator type, mounting configuration, orientation, and termination style—are identical between the two parts.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) rating, indicating equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V. The primary difference is that the AMT313Q-V requires configuration to set its pulses per revolution to 512 to match the fixed specification of the AMT303LD-V. Once configured, functional equivalence is achieved.

Q: What are the key compatibility criteria for substituting the AMT303LD-V?

A: Substitute parts must maintain: 5V supply voltage, incremental encoder type, commutation output with line driver capability, 2mm ~ 8mm open center actuator type, right-angle orientation, chassis mount configuration, and terminal pin termination. The AMT313Q-V satisfies all these requirements.

Q: Does the programmable nature of the AMT313Q-V affect its suitability as a substitute?

A: No. The programmable feature of the AMT313Q-V is an enhancement that allows configuration flexibility. When programmed to 512 PPR, it provides identical functional output to the fixed 512 PPR specification of the AMT303LD-V.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in Box packaging. Both use identical terminal pin termination and mounting interfaces.

Q: What is the inventory status of these parts?

A: The AMT303LD-V has 834 pieces in stock as new original inventory. The AMT313Q-V has 1,349 pieces in stock as new original inventory, providing superior availability for new orders.

Q: Are there compliance or certification differences?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V represents a more current compliance standard (ROHS3) compared to the AMT303LD-V (RoHS Compliant). Both are classified under ECCN EAR99 and HTSUS 8543.70.4500.
