AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1000 pulses per revolution with line driver output and right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback.

The AMT303LD-V carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality 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 support Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Output Type: Must support Commutation output with line driver capability
• RoHS Compliance: Must meet RoHS requirements

The AMT313Q-V meets these substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 1000 PPR of the AMT303LD-V, it maintains compatibility across all mechanical, electrical, and interface parameters that define the product category.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical mechanical interfaces, electrical supply requirements, and regulatory compliance profiles. The AMT313Q-V maintains active product status, ensuring ongoing availability and support.

The primary functional difference is the programmable pulses per revolution capability of the AMT313Q-V, which can be configured to match the 1000 PPR specification of the original part. Both components carry equivalent RoHS and REACH compliance certifications, with the AMT313Q-V meeting the more recent ROHS3 standard.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mounting interfaces, supply voltage requirements, actuator specifications, and termination styles. The AMT313Q-V's programmable PPR can be configured to the 1000 PPR specification of the original part.

Q: What is the primary difference between these two encoders?

A: The AMT303LD-V has a fixed 1000 PPR output, while the AMT313Q-V features programmable pulses per revolution. All other mechanical, electrical, and interface parameters are equivalent.

Q: Are there any compliance or certification differences?

A: Both parts meet RoHS and REACH requirements. The AMT313Q-V carries ROHS3 compliance, which is a more recent standard. Both share identical ECCN and HTSUS classifications.

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

A: The AMT303LD-V has been discontinued by the manufacturer. The AMT313Q-V represents the active product line continuation with enhanced programmability.

Q: Are packaging differences a consideration for substitution?

A: Both components use Terminal Pins termination. Packaging format differences do not affect electrical or mechanical compatibility for chassis mount and motor applications.
