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 Configuration: Must support Commutation output with compatible polarity and line driver characteristics
• Pulses per Revolution: Must be 1000 or programmable to 1000

The AMT313Q-V qualifies as a substitute because it maintains compatibility across all mandatory mechanical and electrical parameters. The key distinction is that the AMT313Q-V features programmable pulses per revolution, allowing configuration to 1000 PPR to match the fixed specification of the AMT303LD-V.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V based on the following criteria:

Compliance and Regulatory Status: The AMT313Q-V maintains ROHS3 compliance, which supersedes the RoHS compliance of the original part. Both components are REACH Unaffected and carry identical MSL ratings, ensuring equivalent environmental and regulatory standing.

Product Lifecycle: The AMT303LD-V is obsolete, while the AMT313Q-V maintains active product status. This ensures long-term availability and continued manufacturer support for the substitute component.

Functional Compatibility: Both encoders share identical mechanical interfaces, electrical supply requirements, and mounting configurations. The programmable pulses per revolution feature of the AMT313Q-V provides equivalent functionality when configured to 1000 PPR, matching the fixed specification of the original part.

Inventory Availability: The AMT313Q-V is currently in stock with 1349 units available, providing immediate procurement capability for replacement or new design applications.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V. The programmable pulses per revolution must be configured to 1000 PPR to match the original specification. No physical modifications are required for mounting or termination.

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

A: The AMT303LD-V has a fixed 1000 PPR specification, while the AMT313Q-V offers programmable pulses per revolution. Both maintain identical supply voltage, actuator type, mounting configuration, and termination style.

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

A: The AMT313Q-V carries ROHS3 compliance, which represents a more current regulatory standard than the RoHS compliance of the AMT303LD-V. Both components maintain identical REACH and MSL ratings.

Q: What packaging is provided with the AMT313Q-V?

A: The AMT313Q-V is supplied in box packaging, as specified by the manufacturer.

Q: Is the AMT313Q-V suitable for the same applications as the AMT303LD-V?

A: Yes. Both encoders are designed for chassis mount and motor applications with identical mechanical and electrical parameters. The right-angle orientation and terminal pin termination are consistent across both parts.
