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 Characteristics: Commutation output with line driver capability

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across these core parameters. While the AMT313Q-V features programmable pulses per revolution rather than fixed 1000 PPR, it can be configured to match the original specification and operates within the same electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V. Both components are manufactured by CUI Devices and share identical mechanical and electrical interfaces. The AMT313Q-V holds active product status, ensuring ongoing availability and supply chain continuity.

Both parts maintain equivalent RoHS and REACH compliance profiles. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards. The programmable pulses per revolution feature of the AMT313Q-V provides operational flexibility while maintaining the capability to match the original 1000 PPR specification through configuration.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modifications?

A: The AMT313Q-V maintains mechanical and electrical compatibility with the AMT303LD-V. Both components feature identical mounting types, orientations, actuator specifications, and termination styles. Configuration of the AMT313Q-V to 1000 PPR operation aligns its functional output with the original part.

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

A: The AMT303LD-V provides fixed 1000 PPR output, while the AMT313Q-V offers programmable PPR configuration. This distinction allows the AMT313Q-V to serve multiple applications beyond the original specification.

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

A: The AMT303LD-V is supplied with terminal pin termination. The AMT313Q-V is packaged in a box format. Both maintain identical electrical and mechanical interfaces.

Q: How do compliance certifications compare?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V meets ROHS3 standards, representing the current regulatory requirement. Both components maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Is the AMT313Q-V suitable for new designs?

A: The AMT313Q-V holds active product status, making it the appropriate choice for new production designs. The obsolete status of the AMT303LD-V makes the AMT313Q-V the recommended selection for ongoing applications.
