AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 800 pulses per revolution with commutation output and integrated line driver functionality. This component is designed for chassis mount and motor applications with right-angle orientation and terminal pin termination.

The AMT303LD-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for new designs or replacement applications where the original part is no longer in production.

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
• MSL Rating: 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 800 PPR. The AMT313Q-V is currently in active production status.

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 AMT313Q-V offers the advantage of active production status and ROHS3 compliance, providing improved long-term availability and regulatory alignment.

The programmable pulses per revolution feature of the AMT313Q-V allows configuration to match the 800 PPR specification of the original part, ensuring functional equivalence in systems where this resolution is required.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V?

A: The AMT313Q-V shares all critical mechanical and electrical parameters with the AMT303LD-V, including supply voltage, actuator type, mounting configuration, and termination style. The programmable PPR feature can be configured to 800 PPR to match the original 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 encoders provide incremental output with commutation functionality at 5V supply.

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

A: The AMT303LD-V is no longer in active production. The AMT313Q-V represents the current active alternative from CUI Devices for this encoder category.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is packaged in a box. Both use terminal pin termination for circuit integration.

Q: Do both encoders meet current compliance standards?

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