Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303LD-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental operation
• Supply Voltage: 5V operation
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Output Configuration: Commutation-based output

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across these core parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 800 PPR. This programmability provides functional equivalence when configured to 800 PPR operation.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V based on the following engineering criteria:

Product Status: The AMT313Q-V maintains active product status, ensuring ongoing manufacturer support, availability, and compliance updates. The AMT303LD-V is obsolete and no longer actively manufactured.

Compliance: Both parts maintain equivalent environmental compliance. The AMT303LD-V is RoHS Compliant, while the AMT313Q-V is ROHS3 Compliant, representing an advancement in regulatory adherence. Both parts are REACH Unaffected and classified under ECCN EAR99.

Functional Equivalence: The AMT313Q-V provides programmable pulse-per-revolution configuration, which allows the encoder to be set to 800 PPR operation, matching the fixed specification of the AMT303LD-V. This programmability offers additional flexibility for system design without compromising the primary application requirement.

Inventory Availability: The AMT313Q-V is available in higher stock quantities (1349 Pcs), compared to the AMT303LD-V (911 Pcs), supporting long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modification?

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V across all mounting, orientation, and termination parameters. The programmable PPR feature of the AMT313Q-V must be configured to 800 PPR to match the fixed specification of the AMT303LD-V. No physical modifications are required.

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

A: The AMT303LD-V has a fixed 800 PPR specification, while the AMT313Q-V features programmable PPR capability. Both encoders share identical mechanical form factors, supply voltage, output type, and mounting configurations.

Q: Are there any compliance differences between the two parts?

A: Both parts maintain equivalent environmental compliance. The AMT303LD-V is RoHS Compliant, and the AMT313Q-V is ROHS3 Compliant, representing an updated compliance standard. Both are REACH Unaffected.

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

A: The AMT303LD-V is no longer actively manufactured by CUI Devices. The AMT313Q-V represents the current active product line for this encoder category, offering programmable functionality as an advancement over the fixed-specification predecessor.

Q: Does packaging differ between these parts?

A: The AMT303LD-V is packaged with a dash designation, while the AMT313Q-V is packaged in a Box. Both maintain identical terminal pin termination and mechanical dimensions suitable for chassis mount and motor applications.
