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 polarity, and 2-pole line driver configuration. 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 system functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V is identified as a substitute for the AMT303LD-V based on the following alignment of critical parameters:

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center configuration
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle mounted
• Termination Style: Both use terminal pins
• Compliance: Both are RoHS compliant and REACH unaffected
• Output Configuration: Both provide commutation output with right-angle orientation

The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 400 PPR. The AMT313Q-V is currently in active product status.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the AMT303LD-V in applications requiring an incremental rotary encoder with the specified mechanical and electrical parameters. The AMT313Q-V maintains compatibility across all critical dimensions: supply voltage, actuator type, mounting configuration, and termination style.

The AMT313Q-V holds active product status with ROHS3 compliance, providing improved regulatory alignment compared to the obsolete AMT303LD-V. Both components maintain identical moisture sensitivity classification and REACH compliance status.

The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility. Applications requiring a fixed 400 PPR output must configure the AMT313Q-V accordingly during implementation.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares identical mechanical mounting, electrical supply voltage, actuator type, and termination configuration with the AMT303LD-V. Physical and electrical compatibility is established across these parameters. The programmable PPR feature of the AMT313Q-V must be configured to 400 PPR to match the fixed output of the AMT303LD-V.

Q: What is the significance of programmable pulses per revolution?

A: The AMT313Q-V allows pulses per revolution to be set during configuration, whereas the AMT303LD-V is fixed at 400 PPR. This provides design flexibility for the substitute part but requires configuration to match the original specification.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is listed with dash packaging notation, while the AMT313Q-V is packaged in boxes. Both use terminal pin termination and are suitable for the same mounting applications.

Q: How do the compliance certifications compare?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 certification, representing current regulatory compliance. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

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

A: Product obsolescence indicates the part is no longer in active production. The AMT313Q-V, as an active product from the same manufacturer with compatible specifications, serves as the current alternative for new designs and replacement applications.
