AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, designed for chassis mount and motor applications with right-angle orientation. This encoder provides 400 pulses per revolution output with commutation, CW, 2-pole configuration and integrated line driver functionality. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V has been identified as a substitute for the AMT303LD-V based on the following alignment of critical parameters:

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center configuration
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle mounted
• Termination Style: Both use terminal pins
• Environmental Compliance: Both are RoHS compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 400 PPR. This programmability provides design flexibility for applications requiring different resolution settings.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the AMT303LD-V in applications where the following conditions are met:

• The application can accommodate programmable pulse-per-revolution configuration, with the AMT313Q-V configured to 400 PPR to match the original specification
• The system design does not depend on the specific line driver implementation of the AMT303LD-V
• The active product status of the AMT313Q-V provides superior long-term availability and supply chain continuity compared to the obsolete AMT303LD-V
• Both components meet current RoHS and REACH compliance requirements, with the AMT313Q-V meeting the more recent ROHS3 standard

The transition from AMT303LD-V to AMT313Q-V is supported by identical mechanical mounting, electrical supply voltage, and environmental ratings.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares identical mounting, voltage supply, actuator type, and termination characteristics. The primary consideration is that the AMT313Q-V requires programming to set the pulse-per-revolution output to 400 PPR to match the fixed specification of the AMT303LD-V. System firmware or configuration must support this programmability.

Q: What is the difference in output type between these two encoders?

A: The AMT303LD-V specifies commutation, CW, 2-pole output with integrated line driver. The AMT313Q-V specifies commutation output. Compatibility depends on whether the receiving system requires the specific line driver implementation of the original part.

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

A: Product obsolescence indicates that the manufacturer has discontinued production. The AMT313Q-V, as an active product from the same manufacturer, provides continued availability and support for equivalent functionality.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is specified with dash packaging, while the AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination.

Q: Do both encoders meet current compliance standards?

A: Yes. Both the AMT303LD-V and AMT313Q-V are RoHS compliant and REACH unaffected. The AMT313Q-V additionally meets the ROHS3 standard, representing compliance with the most current regulatory requirements.
