AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 96 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.

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 with Line Driver capability

The AMT313Q-V meets all mandatory substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 96 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 production status, ensuring long-term availability and supply chain continuity.
• Compliance: Both parts maintain equivalent environmental compliance certifications (RoHS and REACH). The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards.
• Functional Compatibility: Both encoders share identical mechanical mounting, electrical supply requirements, and output signal architecture.
• Programmable Configuration: The AMT313Q-V's programmable pulses per revolution capability allows configuration to match the original 96 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 pulses per revolution feature of the AMT313Q-V must be configured to 96 PPR to match the original specification.

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

A: The primary difference is that the AMT303LD-V has a fixed 96 PPR output, while the AMT313Q-V offers programmable PPR selection. Both share identical supply voltage (5V), mounting type (Chassis Mount, Motors), orientation (Right Angle), and termination style (Terminal Pins).

Q: Are there any packaging differences?

A: The AMT303LD-V is supplied without specified packaging notation, while the AMT313Q-V is packaged in boxes. This difference does not affect functional compatibility.

Q: Does the obsolete status of the AMT303LD-V affect the substitute selection?

A: The obsolete status of the AMT303LD-V necessitates the use of substitute parts. The AMT313Q-V's active production status ensures continued availability and support.

Q: Are both parts RoHS compliant?

A: Yes. The AMT303LD-V is RoHS Compliant, and the AMT313Q-V is ROHS3 Compliant, both meeting current environmental regulations.
