AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 250 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 is specified.

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 all mandatory substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 250 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 maintains active product status, ensuring ongoing manufacturer support and availability.
• Compliance: Both parts maintain equivalent RoHS and REACH compliance status. The AMT313Q-V achieves ROHS3 Compliant certification, meeting current regulatory requirements.
• Functional Compatibility: All critical mechanical and electrical parameters align with the original specification, including supply voltage, mounting configuration, orientation, and termination style.
• Programmable Resolution: The AMT313Q-V offers programmable pulses per revolution, allowing configuration to match the original 250 PPR specification of the AMT303LD-V.

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 programmable PPR feature of the AMT313Q-V must be configured to 250 PPR to match the original encoder specification.

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

A: The primary difference is that the AMT303LD-V has a fixed 250 PPR output, while the AMT313Q-V provides programmable PPR selection. Both share identical supply voltage, mounting type, orientation, actuator type, and termination style.

Q: Are there any packaging differences between the main part and substitute?

A: The AMT303LD-V is supplied with terminal pin termination. The AMT313Q-V is packaged in a box format but maintains the same terminal pin termination style for circuit integration.

Q: Does the AMT313Q-V support the same output type as the AMT303LD-V?

A: Both encoders support commutation output. The AMT303LD-V specifies commutation with CW, 20 Pole, and integrated line driver. The AMT313Q-V supports commutation output, maintaining compatibility with systems designed for the original encoder.

Q: What is the inventory status for the substitute part?

A: The AMT313Q-V has 1349 pieces in stock as new original inventory, providing immediate availability for production and replacement applications.
