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, CW 2-pole configuration, and line driver capability. The encoder is designed for chassis mount and motor applications with a right-angle orientation and 5V supply voltage.

The AMT303LD-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for applications currently utilizing this encoder model.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303LD-V is based on the following critical parameters that must align between the main part and substitute:

• Encoder Type: Incremental
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Detent: No
• Built in Switch: No
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across all these critical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 1000 PPR. This programmability provides additional flexibility while maintaining full mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both parts are manufactured by CUI Devices and maintain identical mechanical and electrical compatibility across all critical parameters.

The AMT313Q-V holds active product status, ensuring ongoing availability and supply chain continuity. The part meets ROHS3 compliance, exceeding the RoHS compliance level of the original AMT303LD-V. Both parts maintain REACH Unaffected status and MSL 1 (Unlimited) ratings.

The programmable pulses per revolution feature of the AMT313Q-V provides system flexibility while maintaining full backward compatibility with applications designed for the fixed 1000 PPR configuration of the AMT303LD-V.
