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, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this encoder.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303LD-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Output Configuration: Commutation with line driver capability
• Detent and Built-in Switch: No

The AMT313Q-V meets these core compatibility criteria. While the AMT313Q-V features programmable pulses per revolution rather than the fixed 1024 PPR of the AMT303LD-V, this parameter is configurable and does not prevent functional substitution in applications where the encoder resolution can be programmed to match the original specification.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and termination characteristics. The AMT313Q-V maintains full RoHS and REACH compliance, with ROHS3 certification representing current regulatory alignment.

The primary distinction is the programmable pulses per revolution specification on the AMT313Q-V, which can be configured to match the 1024 PPR output of the original part. The AMT313Q-V is currently in active production status, ensuring supply chain continuity and long-term availability.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V. The programmable PPR feature of the AMT313Q-V must be configured to 1024 pulses per revolution to match the original encoder output specification.

Q: What is the significance of the programmable PPR feature on the AMT313Q-V?

A: The programmable pulses per revolution allows the AMT313Q-V to be configured for different resolution requirements. For direct substitution of the AMT303LD-V, program the AMT313Q-V to output 1024 PPR.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with terminal pin termination. The AMT313Q-V is packaged in a box configuration. Both use identical terminal pin termination style for circuit integration.

Q: Do both parts meet current regulatory requirements?

A: Yes. The AMT303LD-V is RoHS Compliant and REACH Unaffected. The AMT313Q-V is ROHS3 Compliant and REACH Unaffected, representing current regulatory standards.

Q: What is the supply voltage requirement for both encoders?

A: Both the AMT303LD-V and AMT313Q-V operate at 5V supply voltage.

Q: Are the mounting and orientation specifications identical?

A: Yes. Both encoders feature chassis mount and motor mounting capability with right-angle orientation and 2mm ~ 8mm open center actuator type.
