AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 250 pulses per revolution with commutation output, CCW rotation, 4-pole configuration, and integrated line driver. The encoder 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 compatibility and ensure continued availability for applications currently utilizing this encoder model.

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 be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Output Type: Must support Commutation with 4-Pole configuration

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 250 PPR of the AMT303LD-V), this parameter does not prevent substitution when the encoder is configured to operate at 250 PPR. The programmable capability provides additional flexibility for the application.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Both encoders share identical mechanical and electrical interface specifications, including supply voltage, actuator type, mounting configuration, and termination style.

The AMT313Q-V carries Active product status, ensuring ongoing manufacturer support and availability. Both parts maintain equivalent RoHS and REACH compliance certifications, with the AMT313Q-V meeting the more recent ROHS3 standard. The programmable pulses per revolution feature of the AMT313Q-V does not compromise substitution compatibility when configured to 250 PPR operation.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting, electrical interface voltage (5V), actuator specifications (2mm ~ 8mm Open Center), and termination style (Terminal Pins). The AMT313Q-V must be configured to 250 PPR to match the original encoder output resolution.

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

A: The AMT303LD-V has a fixed 250 PPR output, while the AMT313Q-V features programmable pulses per revolution. This allows the AMT313Q-V to be configured for multiple resolution settings, including 250 PPR.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The AMT303LD-V meets RoHS Compliant status, while the AMT313Q-V meets the more recent ROHS3 Compliant standard. Both maintain REACH Unaffected status and identical Moisture Sensitivity Level (MSL) ratings.

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

A: The AMT303LD-V is no longer in active production. The AMT313Q-V represents the current active alternative from CUI Devices for this encoder category.

Q: Are the packaging specifications identical?

A: The AMT303LD-V uses terminal pin termination, while the AMT313Q-V is supplied in Box packaging. Both maintain identical electrical and mechanical interface specifications.
