Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303LD-V is determined by the following critical parameters:

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

The AMT313Q-V qualifies as a substitute based on matching all mandatory mechanical and electrical parameters. The key distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 800 PPR. This programmability provides design flexibility while maintaining full compatibility with the mechanical and electrical interface requirements.

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V. Selection should be based on the following factors:

Product Status: The AMT313Q-V maintains active production status with confirmed inventory availability (1349 units), whereas the AMT303LD-V is obsolete. This ensures long-term supply chain reliability and support.

Compliance: Both parts maintain RoHS compliance. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards. Both parts are REACH Unaffected and classified under ECCN EAR99.

Mechanical and Electrical Compatibility: The AMT313Q-V preserves all critical interface parameters including 5V supply voltage, right-angle orientation, chassis mount configuration, and terminal pin termination. The mechanical actuator range (2mm ~ 8mm Open Center) remains identical.

Functional Consideration: The AMT313Q-V offers programmable pulses per revolution, which can be configured to match the 800 PPR specification of the original part or adapted to alternative resolution requirements within system constraints.

Frequently Asked Questions (FAQ)

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

A: Yes. The AMT313Q-V maintains identical mechanical mounting, electrical supply voltage (5V), actuator type, orientation, and termination style. The programmable PPR feature can be configured to match the original 800 PPR specification.

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

A: The AMT303LD-V has a fixed 800 PPR output, while the AMT313Q-V features programmable pulses per revolution. Both share identical mechanical interfaces and electrical supply requirements.

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

A: Both parts are RoHS compliant and REACH Unaffected. The AMT313Q-V achieves ROHS3 compliance, which represents the current regulatory standard. Both are classified under ECCN EAR99.

Q: What is the packaging difference?

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

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

A: The AMT303LD-V has been discontinued by the manufacturer. The AMT313Q-V represents the active product line continuation with enhanced programmability while maintaining full mechanical and electrical compatibility.

Q: Is the AMT313Q-V programmable feature a requirement for substitution?

A: No. The programmable feature is an enhancement that allows configuration flexibility. For direct replacement applications, the AMT313Q-V can be programmed to operate at 800 PPR, matching the original specification exactly.
