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
• Orientation: Right angle
• Termination: Terminal pins
• Actuator Range: 2mm ~ 8mm open center

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 design flexibility while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V based on functional and regulatory alignment:

• Active Product Status: The AMT313Q-V maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both components meet RoHS and REACH requirements. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards.
• Electrical Compatibility: Identical 5V supply voltage and incremental encoder operation ensure direct functional replacement.
• Mechanical Compatibility: Matching mounting type, orientation, actuator range, and termination style enable direct physical integration.
• Programmable Resolution: The AMT313Q-V offers programmable pulses per revolution, allowing configuration to 250 PPR to match the original specification or adjustment to alternative resolutions as system requirements permit.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical electrical supply voltage (5V), mounting configuration (chassis mount, motors), orientation (right angle), and termination style (terminal pins). The mechanical actuator range (2mm ~ 8mm open center) is also identical, enabling direct physical and electrical substitution.

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

A: The AMT303LD-V provides a fixed 250 pulses per revolution output, while the AMT313Q-V features programmable pulse resolution. This allows the AMT313Q-V to be configured to 250 PPR or other resolutions depending on application requirements.

Q: Are there compliance or certification differences?

A: Both components are RoHS compliant and REACH unaffected. The AMT313Q-V achieves ROHS3 compliance, which represents the current regulatory standard. Both share identical ECCN (EAR99) and HTSUS (8543.70.4500) classifications.

Q: What is the packaging difference?

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

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

A: Obsolescence typically reflects manufacturer discontinuation of production. The AMT313Q-V, as an active product with enhanced programmability, represents the current generation alternative within the CUI Devices encoder portfolio.
