Key Parameters

Substitute Part Grouping Explanation

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

Matching Parameters:

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

Functional Difference: The AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 800 PPR. This programmability provides design flexibility for the substitute part while maintaining compatibility with the core mechanical and electrical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Selection of the AMT313Q-V is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance, meeting current regulatory requirements
• Identical mechanical interface and mounting specifications
• Matching electrical supply voltage and actuator specifications
• Programmable PPR capability, which accommodates the fixed 800 PPR requirement of the original design while providing additional flexibility for future applications

The programmable nature of the AMT313Q-V does not compromise compatibility; the encoder can be configured to operate at 800 PPR to match the original specification.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting, electrical supply voltage, actuator type, and termination specifications. The AMT313Q-V can be configured to operate at 800 PPR to match the original design requirement.

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

A: The AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 800 PPR. This programmability provides design flexibility while maintaining full mechanical and electrical compatibility.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant. The AMT313Q-V meets ROHS3 standards, representing a more current compliance certification than the RoHS Compliant designation of the AMT303LD-V. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

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

A: The AMT303LD-V has reached end-of-life status. The AMT313Q-V represents the active product line continuation from CUI Devices for this encoder category.

Q: Are the packaging specifications identical?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. Both maintain identical component dimensions and terminal pin configurations for mechanical compatibility.
