AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 pulses per revolution with commutation output, CW rotation, 2-pole configuration, and integrated line driver. 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 design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the AMT303LD-V are 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 be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Output Type: Must support Commutation output
• RoHS Compliance: Must meet or exceed RoHS requirements

The AMT313Q-V qualifies as a substitute because it maintains compatibility across all critical mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution rather than the fixed 1024 PPR of the AMT303LD-V. This programmability allows the AMT313Q-V to be configured to match the original 1024 PPR specification when required.

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V based on the following engineering criteria:

Compliance and Regulatory Status: The AMT313Q-V meets ROHS3 compliance, which exceeds the RoHS Compliant status of the original part. Both components maintain REACH Unaffected status and identical MSL ratings, ensuring equivalent environmental and regulatory performance.

Product Availability: The AMT313Q-V is classified as Active, providing assured long-term availability and supply chain continuity compared to the obsolete AMT303LD-V.

Functional Compatibility: All mechanical and electrical parameters align with the original specification. The programmable PPR feature of the AMT313Q-V provides operational flexibility while maintaining the ability to be configured to the original 1024 PPR setting.

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 critical parameters including mounting type, orientation, actuator type, supply voltage, and termination style. Configuration of the programmable PPR to 1024 is required to match the original specification.

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

A: The AMT303LD-V has a fixed 1024 PPR output, while the AMT313Q-V features programmable PPR. Both maintain identical mechanical form factors, electrical interfaces, and mounting characteristics.

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

A: The AMT313Q-V carries ROHS3 compliance, which represents a higher standard than the RoHS Compliant status of the AMT303LD-V. Both parts maintain equivalent MSL ratings and REACH status.

Q: What packaging is available for the substitute part?

A: The AMT313Q-V is supplied in Box packaging, as specified by the manufacturer.

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

A: Yes. Both encoders are rated for identical mounting types (Chassis Mount, Motors) and share the same right-angle orientation and terminal pin termination, making them suitable for equivalent applications.
