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:

• 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 mounting
• 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 distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 400 PPR. The AMT313Q-V is currently in active production status, addressing the obsolescence of the AMT303LD-V.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Selection is based on:

• Product Status Alignment: The AMT313Q-V is in active production, ensuring long-term availability and supply chain continuity
• Compliance Enhancement: The AMT313Q-V meets ROHS3 compliance, representing an advancement over the RoHS Compliant status of the original part
• Functional Compatibility: All critical mechanical and electrical parameters align, including 5V supply, right-angle orientation, chassis mount capability, and terminal pin termination
• Programmable Resolution: The AMT313Q-V offers programmable pulses per revolution, providing design flexibility. When configured to 400 PPR, it delivers equivalent resolution to the AMT303LD-V

Frequently Asked Questions (FAQ)

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

A: Yes, provided the AMT313Q-V is programmed to 400 PPR to match the fixed resolution of the AMT303LD-V. All mechanical mounting parameters, electrical supply voltage, and output characteristics are compatible.

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

A: The AMT313Q-V is in active production status and offers programmable resolution, eliminating the need for multiple part numbers across different PPR requirements. It also meets ROHS3 compliance.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. Both use terminal pin termination and are suitable for the same mounting applications.

Q: Do both encoders support the same supply voltage?

A: Yes, both operate at 5V supply voltage with identical actuator type (2mm ~ 8mm open center) and mounting configurations.

Q: What compliance certifications apply to both parts?

A: Both parts are REACH unaffected and RoHS compliant. The AMT313Q-V additionally meets ROHS3 compliance standards.
