Key Parameters

Substitute Part Grouping Explanation

The AMT313Q-V is identified as a substitute for the AMT303LD-V based on the following alignment of critical parameters:

• Encoder Type: Both are incremental encoders
• Supply Voltage: Both operate at 5V
• Actuator Type: Both feature 2mm ~ 8mm open center actuators
• Mounting Type: Both support chassis mount and motor applications
• Orientation: Both are right-angle configurations
• Termination Style: Both use terminal pins
• Compliance: Both are RoHS compliant and REACH unaffected
• Moisture Sensitivity: Both have MSL 1 (Unlimited)

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 250 PPR. The AMT313Q-V maintains compatibility across all mechanical and electrical interfaces while offering enhanced flexibility through programmable output resolution.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the AMT303LD-V in applications requiring incremental rotary encoding with the specified mechanical and electrical parameters. The substitute maintains full compatibility across mounting, orientation, actuator type, and supply voltage specifications.

The AMT313Q-V carries active product status, ensuring ongoing manufacturer support and availability. Both components meet RoHS and REACH compliance requirements. The AMT313Q-V achieves ROHS3 compliance, representing current regulatory standards.

The programmable pulses per revolution feature of the AMT313Q-V provides operational flexibility. Applications requiring a fixed 250 PPR output can configure the substitute accordingly, while designs may benefit from the ability to adjust resolution without component replacement.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical mechanical mounting, orientation, actuator specifications, and 5V supply voltage requirements. Terminal pin termination is consistent across both parts. Physical and electrical interfaces are compatible.

Q: What is the significance of programmable pulses per revolution in the AMT313Q-V?

A: The AMT313Q-V allows output resolution configuration, whereas the AMT303LD-V is fixed at 250 PPR. If your application requires exactly 250 PPR, the AMT313Q-V can be programmed to this value. This feature enables the substitute to serve multiple design requirements without inventory diversification.

Q: Are there compliance differences between these components?

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

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

A: Obsolete status indicates the manufacturer has discontinued production. The AMT313Q-V, with active product status, ensures continued availability and manufacturer support for new applications and replacements.

Q: Are packaging differences relevant to substitution?

A: The AMT303LD-V uses standard packaging, while the AMT313Q-V is supplied in box packaging. This difference does not affect component functionality or mechanical compatibility. Packaging selection depends on inventory and handling requirements.
