AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 400 pulses per revolution with commutation output, CCW rotation, 4-pole configuration, and integrated line driver. The unit 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 system compatibility and ensure continued availability for applications currently utilizing this encoder model.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303LD-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental
• Voltage - Supply: 5V
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Actuator Type: 2mm ~ 8mm Open Center
• Output Configuration: Commutation output with line driver capability

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across these core parameters. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 400 PPR of the AMT303LD-V), this represents an enhancement rather than a limitation, as the programmable output can be configured to match the original 400 PPR specification when required.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Selection of the AMT313Q-V is supported by the following factors:

• Product Status: The AMT313Q-V maintains active product status, ensuring ongoing availability and supply chain continuity.
• Compliance: The AMT313Q-V meets ROHS3 compliance and maintains REACH Unaffected status, satisfying regulatory requirements equivalent to or exceeding the original part.
• Electrical Compatibility: Both parts operate at 5V supply voltage with identical mounting, orientation, and termination configurations.
• Mechanical Compatibility: Actuator type, mounting method, and physical orientation are identical between the two parts.
• Output Configuration: The AMT313Q-V provides programmable pulses per revolution, which can be configured to match the 400 PPR specification of the original part.

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 across all mounting, orientation, and termination parameters. The programmable PPR feature of the AMT313Q-V must be configured to 400 PPR to match the original specification.

Q: What is the difference between fixed and programmable pulses per revolution?

A: The AMT303LD-V provides a fixed output of 400 PPR. The AMT313Q-V allows PPR configuration through programming, providing flexibility for different application requirements while maintaining the ability to operate at 400 PPR when configured accordingly.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant and REACH Unaffected. The AMT313Q-V meets ROHS3 compliance, which represents an updated standard. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging difference?

A: The AMT303LD-V is supplied without specified packaging designation. The AMT313Q-V is supplied in box packaging.

Q: Is the AMT313Q-V suitable for motor and chassis mount applications?

A: Yes. Both the AMT303LD-V and AMT313Q-V are designed for chassis mount and motor applications with identical right-angle orientation and terminal pin termination.
