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 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 functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303LD-V are identified based on the following critical parameters that must align for functional equivalence:

• Encoder Type: Incremental operation
• Supply Voltage: 5V operation
• Actuator Type: 2mm ~ 8mm Open Center compatibility
• Mounting Type: Chassis Mount, Motors capability
• Orientation: Right Angle configuration
• Termination Style: Terminal Pins interface
• Manufacturer: CUI Devices product line

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 1000 PPR of the AMT303LD-V, it maintains electrical and mechanical compatibility across all other specified parameters. The programmable capability of the substitute part provides functional flexibility while preserving interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V based on electrical and mechanical parameter alignment. The substitute part maintains active product status with CUI Devices, ensuring ongoing availability and support.

Both parts satisfy identical compliance requirements: RoHS compliance (with the substitute meeting the more recent ROHS3 standard), REACH unaffected status, and unlimited moisture sensitivity level rating. The ECCN and HTSUS classifications remain consistent between the two parts.

The primary functional difference is the programmable pulses per revolution capability of the AMT313Q-V, which provides configuration flexibility while maintaining full interface compatibility with systems designed for the AMT303LD-V.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V maintains mechanical and electrical interface compatibility with the AMT303LD-V across all specified parameters: 5V supply voltage, right-angle orientation, chassis mount capability, terminal pin termination, and 2mm ~ 8mm open center actuator compatibility. The programmable pulses per revolution feature of the substitute part does not prevent direct substitution.

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

A: The AMT303LD-V provides fixed 1000 pulses per revolution output, while the AMT313Q-V offers programmable pulses per revolution. Both maintain identical mechanical mounting, electrical interface, and supply voltage specifications.

Q: Are there compliance or certification differences between the parts?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V meets the more recent ROHS3 standard. Both carry unlimited moisture sensitivity level ratings and identical ECCN and HTSUS classifications.

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

A: The AMT303LD-V carries obsolete product status from the manufacturer. The AMT313Q-V is the active equivalent part available for new designs and replacement applications.

Q: Are packaging considerations relevant for substitution?

A: Both parts use terminal pin termination for direct interface compatibility. The AMT313Q-V is supplied in box packaging. Packaging format does not affect electrical or mechanical substitution capability.
