AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 500 pulses per revolution with commutation output and line driver capability. 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 functionality and ensure continued availability for new designs or replacement applications.

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
• Output Type: Both provide commutation output
• Compliance: Both are RoHS compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 500 PPR. The AMT313Q-V is currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and compliance certifications. The AMT313Q-V maintains active production status, ensuring long-term availability and supply chain continuity.

The AMT313Q-V's programmable pulses per revolution capability provides design flexibility beyond the fixed 500 PPR specification of the AMT303LD-V. This feature does not preclude substitution; the programmable encoder can be configured to operate at 500 PPR to match the original specification.

Both components meet RoHS and REACH compliance requirements. The AMT313Q-V carries ROHS3 certification, representing current compliance standards.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mounting type, orientation, supply voltage, actuator type, and termination style. The mechanical and electrical interfaces are compatible.

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

A: The AMT313Q-V allows configuration of pulse output to match system requirements. For applications requiring 500 PPR, the encoder can be programmed to this specification, matching the AMT303LD-V behavior.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 certification, which represents the current RoHS compliance standard. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

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 mechanical compatibility.

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

A: Obsolete status indicates the part is no longer in active production. The AMT313Q-V, as an active production alternative, provides continued access to equivalent encoder functionality.
