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 output with line driver capability

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across these core parameters. The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 512 PPR. This programmability provides functional equivalence for applications requiring 512 PPR operation while offering additional flexibility for alternative configurations.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both parts maintain identical compliance certifications (RoHS, REACH, ECCN EAR99, HTSUS 8543.70.4500) and share the same moisture sensitivity classification. The AMT313Q-V carries active product status, ensuring ongoing availability and supply chain continuity.

The AMT313Q-V's programmable PPR configuration provides functional equivalence to the fixed 512 PPR specification of the AMT303LD-V. Both encoders operate at 5V supply voltage and maintain identical mechanical specifications for actuator type, mounting configuration, and termination style.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical electrical supply requirements (5V), mechanical mounting specifications (chassis mount, right angle orientation), actuator compatibility (2mm ~ 8mm open center), and termination style (terminal pins). The AMT313Q-V's programmable PPR capability accommodates the AMT303LD-V's fixed 512 PPR specification.

Q: What is the primary difference between these two encoder models?

A: The AMT303LD-V features a fixed 512 pulses per revolution output, while the AMT313Q-V provides programmable PPR configuration. Both maintain identical commutation output with line driver functionality and 5V supply voltage operation.

Q: Are there compliance or certification differences between the two parts?

A: Both parts maintain REACH Unaffected status and identical ECCN and HTSUS classifications. The AMT313Q-V carries ROHS3 Compliant certification compared to the AMT303LD-V's RoHS Compliant status. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

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

A: The AMT303LD-V carries obsolete product status. The AMT313Q-V, with active product status, represents the current equivalent offering from CUI Devices for this encoder category.

Q: Are packaging differences relevant to substitution?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in box packaging. Both maintain identical terminal pin termination style and mechanical form factor for chassis mount applications.
