Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V qualifies as a substitute 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 design
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configuration
• Termination Style: Both use terminal pins
• Regulatory 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 250 PPR. The AMT313Q-V maintains active product status, making it suitable for applications requiring the same mechanical and electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting characteristics, electrical supply requirements, and interface specifications. The AMT313Q-V maintains active product status with current manufacturing support and improved RoHS3 compliance certification.

For applications requiring a fixed 250 PPR output, the programmable capability of the AMT313Q-V can be configured to match the original specification. The active product status of the AMT313Q-V ensures long-term availability and supply chain continuity compared to the obsolete AMT303LD-V.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mounting type, orientation, actuator type, termination style, and 5V supply voltage. The mechanical and electrical interfaces are compatible.

Q: What is the key difference between these two encoders?

A: The AMT303LD-V has a fixed 250 PPR output, while the AMT313Q-V features programmable PPR. The AMT313Q-V can be configured to output 250 PPR to match the original specification.

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 with enhanced programmability.
