AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 200 pulses per revolution with commutation output, CW 2-pole configuration, 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 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

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
• RoHS Compliance: Must meet or exceed RoHS requirements

The AMT313Q-V meets all mandatory substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 200 PPR of the AMT303LD-V), this represents an enhancement in flexibility rather than a functional incompatibility, as the programmable output can be configured to match the original 200 PPR specification.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the AMT303LD-V based on the following factors:

Product Status: The AMT313Q-V is active and in production, ensuring long-term availability and supply chain continuity. The AMT303LD-V is obsolete, making the substitute necessary for ongoing applications.

Compliance: The AMT313Q-V exceeds the compliance profile of the original part, meeting ROHS3 Compliant standards compared to the RoHS Compliant designation of the AMT303LD-V. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

Functional Compatibility: All critical electrical and mechanical parameters align between the two parts. The programmable pulses per revolution feature of the AMT313Q-V provides operational flexibility while maintaining backward compatibility when configured to 200 PPR.

Inventory Status: The AMT313Q-V is available with 1,349 units in stock, providing immediate procurement capability.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modifications?

A: The AMT313Q-V meets all mandatory electrical and mechanical compatibility criteria. The programmable PPR feature requires configuration to match the original 200 PPR specification, but this is a standard setup procedure and does not require hardware modifications.

Q: What is the difference between fixed 200 PPR and programmable PPR?

A: The AMT303LD-V provides a fixed output of 200 pulses per revolution. The AMT313Q-V allows the PPR value to be programmed during initialization. For applications requiring 200 PPR, the AMT313Q-V can be configured to this value, providing identical functional output.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V uses terminal pin termination in standard packaging. The AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination style, ensuring mechanical and electrical compatibility in the application.

Q: Why is the AMT303LD-V obsolete?

A: The AMT303LD-V has been discontinued by CUI Devices. The AMT313Q-V represents the current production alternative within the CUI Devices encoder portfolio, offering enhanced programmability while maintaining core functional parameters.

Q: Are there any compliance concerns with substitution?

A: No. The AMT313Q-V meets or exceeds all compliance requirements of the original part, including RoHS, REACH, and ECCN classifications.
