Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMT303LD-V is based on the following critical parameters that must align for functional compatibility:

• Encoder Type: Incremental operation
• Supply Voltage: 5V operation
• Mounting Configuration: Chassis mount, motors; right-angle orientation
• Termination: Terminal pins
• Actuator Compatibility: 2mm ~ 8mm open center shaft
• Output Characteristics: Commutation output with line driver capability

The AMT313Q-V qualifies as a substitute based on matching these core parameters. The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 250 PPR. This programmability provides operational flexibility while maintaining all other functional and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and output characteristics. The AMT313Q-V maintains active product status, ensuring ongoing availability and supply chain continuity.

The AMT313Q-V carries ROHS3 compliance, representing a more current regulatory standard than the RoHS compliance of the original part. Both components meet REACH requirements and carry identical moisture sensitivity ratings.

The programmable pulses per revolution feature of the AMT313Q-V does not compromise compatibility when configured to 250 PPR operation, matching the original specification of the AMT303LD-V.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mounting type, orientation, supply voltage, actuator compatibility, and termination style. The AMT313Q-V can be configured to operate at 250 PPR, matching the original part's output resolution.

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

A: The AMT303LD-V has a fixed 250 PPR output, while the AMT313Q-V features programmable PPR selection. This programmability provides design flexibility without affecting mechanical or electrical compatibility.

Q: Are there compliance differences between the two parts?

A: The AMT313Q-V carries ROHS3 compliance, which supersedes the RoHS compliance of the AMT303LD-V. Both parts meet REACH requirements and carry identical moisture sensitivity ratings.

Q: Does the packaging differ between these encoders?

A: The AMT303LD-V is specified with dash packaging, while the AMT313Q-V is supplied in box packaging. This does not affect component functionality or performance.

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

A: Product obsolescence reflects manufacturing discontinuation. The AMT313Q-V, as an active product from the same manufacturer, provides continued access to equivalent encoder functionality.
