AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 200 pulses per revolution with commutation output, CW polarity, and 2-pole line driver configuration. This component is designed for chassis mount and motor applications with right-angle orientation and terminal pin termination.

The AMT303LD-V carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute for the AMT303LD-V based on the following matching parameters:

• Encoder Type: Both are incremental encoders
• Voltage Supply: 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
• Compliance: Both are RoHS compliant and REACH unaffected

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 200 PPR. The AMT313Q-V also carries an active product status, making it suitable for ongoing production and replacement scenarios.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components meet identical mechanical and electrical interface requirements for chassis mount and motor applications. The AMT313Q-V maintains full compatibility with the 5V supply voltage, open center actuator configuration, right-angle mounting, and terminal pin termination.

The AMT313Q-V's programmable PPR capability provides design flexibility beyond the fixed 200 PPR specification of the AMT303LD-V. When configured to 200 PPR, the AMT313Q-V delivers functional equivalence. The active product status of the AMT313Q-V ensures ongoing availability and support for new production and field replacements.

Both components carry equivalent compliance certifications: RoHS compliance, REACH unaffected status, and EAR99 ECCN classification.

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 supply voltage, actuator configuration, and termination style. The AMT313Q-V must be configured to 200 PPR to match the original specification.

Q: What is the primary advantage of the AMT313Q-V over the AMT303LD-V?

A: The AMT313Q-V features programmable pulses per revolution, allowing configuration flexibility for different resolution requirements. The AMT303LD-V is fixed at 200 PPR.

Q: Are there compliance differences between these two encoders?

A: Both encoders are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 compliance, representing a more recent standard iteration than the AMT303LD-V's RoHS compliance.

Q: What is the packaging difference?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. This does not affect functional compatibility.

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

A: Obsolete status indicates the manufacturer has discontinued production. The AMT313Q-V, with active product status, is the recommended alternative for ongoing applications.

Q: Are both encoders suitable for motor applications?

A: Yes. Both encoders support chassis mount and motor mounting configurations with identical mechanical interfaces.
