Key Parameters

Substitute Part Grouping Explanation

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

Matching Parameters:

• Encoder Type: Incremental
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• RoHS Compliance: Both parts meet RoHS standards
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Key Difference:

• Pulses per Revolution: AMT303LD-V is fixed at 1000 PPR, while AMT313Q-V features programmable PPR capability

The AMT313Q-V maintains functional and mechanical compatibility while offering programmable pulse resolution, providing flexibility for applications requiring variable encoder configurations.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is an active product with ROHS3 compliance, providing a direct substitute path for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and interface specifications.

The primary distinction is the programmable pulse resolution of the AMT313Q-V, which accommodates the fixed 1000 PPR specification of the AMT303LD-V while offering additional configuration flexibility for future applications.

Selection of the AMT313Q-V is supported by its active product status, enhanced RoHS compliance level, and maintained availability in inventory.

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, 5V supply voltage, actuator type, orientation, and termination specifications. The AMT313Q-V can be configured to operate at 1000 PPR to match the original specification.

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