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 line driver capability. 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 of the AMT303LD-V is based on the following critical parameters that must align for functional compatibility:

• Encoder Type: Incremental operation
• Supply Voltage: 5V operation
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Output Characteristics: 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 250 PPR of the AMT303LD-V, it maintains electrical and mechanical compatibility across all other specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V based on functional and compliance alignment. Both components maintain identical electrical supply requirements (5V), mechanical mounting specifications (chassis mount, right angle), and environmental compliance ratings (RoHS and REACH unaffected status).

The primary distinction is the programmable pulses per revolution capability of the AMT313Q-V, which provides operational flexibility compared to the fixed 250 PPR specification of the AMT303LD-V. The AMT313Q-V's active product status ensures ongoing availability and support.

Both components carry equivalent moisture sensitivity and regulatory compliance certifications, supporting direct substitution in applications requiring incremental rotary encoding with commutation output.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical mechanical mounting (chassis mount, right angle), electrical supply (5V), actuator specifications (2mm ~ 8mm open center), and termination style (terminal pins). The AMT313Q-V's programmable PPR capability accommodates the AMT303LD-V's fixed 250 PPR specification.

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

A: The AMT303LD-V provides fixed 250 pulses per revolution output, while the AMT313Q-V offers programmable PPR configuration. Both maintain identical 5V supply voltage, right-angle orientation, and commutation output characteristics.

Q: Are there packaging differences between the AMT303LD-V and AMT313Q-V?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. Both components maintain identical terminal pin termination and mounting specifications.

Q: Do both encoders meet current regulatory compliance standards?

A: Yes. The AMT303LD-V is RoHS Compliant, and the AMT313Q-V is ROHS3 Compliant. Both are REACH Unaffected and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

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

A: The AMT303LD-V has reached end-of-life status. The AMT313Q-V represents the active product line continuation, offering enhanced programmability while maintaining full mechanical and electrical compatibility.
