AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 800 pulses per revolution with commutation output, CCW rotation, 8-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

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

• Encoder Type: Incremental
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• RoHS and REACH Compliance: Maintained across substitutes

The AMT313Q-V is identified as a substitute part. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 800 PPR of the AMT303LD-V), it maintains all other critical parameters including supply voltage, actuator type, mounting configuration, orientation, and termination style. The programmable PPR capability of the AMT313Q-V provides functional equivalence when configured to 800 PPR operation.

Parameter Comparison

Engineering Selection Recommendations

The AMT303LD-V is obsolete and no longer in active production. The AMT313Q-V is the identified substitute, currently in active production status with improved compliance certification (ROHS3 versus RoHS Compliant).

Selection of the AMT313Q-V as a replacement requires configuration of the programmable pulses per revolution parameter to 800 PPR to match the original AMT303LD-V specification. Both encoders maintain identical mechanical mounting, electrical supply voltage, and termination characteristics, supporting direct functional substitution in existing applications.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V provides functional equivalence when the programmable PPR is configured to 800 PPR. All mechanical and electrical interface parameters are identical. Configuration of the PPR setting is required during integration.

Q: What are the key compatibility parameters between these encoders?

A: Critical compatibility parameters include 5V supply voltage, 2mm ~ 8mm open center actuator type, right-angle orientation, chassis mount configuration, and terminal pin termination. Both encoders maintain these specifications.

Q: Are there compliance differences between the AMT303LD-V and AMT313Q-V?

A: The AMT313Q-V carries ROHS3 compliance certification, representing an updated compliance standard compared to the RoHS Compliant designation of the AMT303LD-V. Both maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging difference between these parts?

A: The AMT303LD-V is supplied with standard packaging. The AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination for circuit integration.

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

A: The AMT303LD-V has reached end-of-life status in the manufacturer's product portfolio. The AMT313Q-V represents the active production alternative with programmable configuration capability, providing extended product lifecycle support.
