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:

• Manufacturer: CUI Devices (same manufacturer ensures design compatibility)
• Encoder Type: Incremental (same functional classification)
• Output Type: Commutation (compatible output signal format)
• Voltage - Supply: 5V (identical supply voltage requirement)
• Actuator Type: 2mm ~ 8mm Open Center (mechanical compatibility)
• Mounting Type: Chassis Mount, Motors (same application context)
• Orientation: Right Angle (identical physical orientation)
• Termination Style: Terminal Pins (same connection method)
• RoHS Status: ROHS3 Compliant (meets or exceeds original compliance)

Key Difference:

• Pulses per Revolution: AMT313Q-V features programmable PPR versus the fixed 1024 PPR of the AMT303LD-V. This programmability provides flexibility for applications requiring different resolution settings while maintaining the same hardware interface.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the obsolete AMT303LD-V based on the following factors:

Product Status: The AMT313Q-V maintains active product status, ensuring ongoing availability and manufacturer support, whereas the AMT303LD-V is obsolete.

Compliance Alignment: The AMT313Q-V meets ROHS3 compliance, which supersedes the RoHS compliance of the original part. Both parts maintain REACH Unaffected and EAR99 ECCN classifications, ensuring regulatory consistency.

Functional Compatibility: Both encoders share identical supply voltage (5V), mounting configuration (Chassis Mount, Motors), physical orientation (Right Angle), and termination method (Terminal Pins). The commutation output type is maintained in the substitute part.

Resolution Flexibility: The programmable PPR capability of the AMT313Q-V provides operational flexibility. Applications requiring the fixed 1024 PPR specification can configure the substitute part accordingly, while systems with variable resolution requirements gain additional functionality.

Frequently Asked Questions (FAQ)

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

A: Yes, the AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V. Both parts share identical mounting type, orientation, supply voltage, actuator type, and termination style.
