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 all critical mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 96 PPR. This programmability provides additional flexibility while preserving all other functional requirements.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is an active product with current manufacturing support, whereas the AMT303LD-V is obsolete. Both parts maintain identical compliance certifications (RoHS and REACH unaffected status) and equivalent moisture sensitivity ratings.

The AMT313Q-V provides the advantage of programmable pulse-per-revolution configuration, allowing system adaptation without component substitution. The AMT303LD-V's fixed 96 PPR specification can be replicated through the AMT313Q-V's programmable feature, ensuring functional equivalence for existing applications.

Current inventory availability favors the AMT313Q-V (1349 pcs) over the AMT303LD-V (1148 pcs), supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mechanical mounting, electrical supply requirements, actuator specifications, and termination methods. The AMT313Q-V's programmable PPR can be configured to match the AMT303LD-V's 96 PPR specification.

Q: What is the primary functional difference between these two parts?

A: The AMT303LD-V has a fixed 96 pulses per revolution output. The AMT313Q-V provides programmable pulse-per-revolution configuration, offering greater application flexibility while maintaining all other electrical and mechanical characteristics.

Q: Are there packaging differences between the main part and substitute?

A: The AMT303LD-V packaging is listed as standard, while the AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination and are suitable for the same mounting applications.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the AMT303LD-V and AMT313Q-V are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 certification, representing the current compliance standard.

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

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The AMT313Q-V represents the active product line continuation from CUI Devices for this encoder category.
