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, 4-pole configuration, 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 carries an obsolete product status. 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 qualifies as a substitute for the AMT303LD-V based on the following alignment of critical parameters:

• Encoder Type: Both are incremental encoders
• Output Type: Both feature commutation output with right-angle orientation
• Supply Voltage: Both operate at 5V
• Actuator Type: Both accommodate 2mm ~ 8mm open center actuators
• Mounting Configuration: Both support chassis mount and motor applications
• Termination Style: Both use terminal pins
• Environmental Compliance: Both meet RoHS and REACH requirements with MSL 1 rating

The primary distinction is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 500 PPR. The AMT313Q-V carries an active product status, making it suitable for applications requiring the AMT303LD-V's functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is the designated substitute for the obsolete AMT303LD-V. Both components share identical mechanical mounting, electrical supply requirements, and environmental compliance certifications. The AMT313Q-V maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The programmable PPR capability of the AMT313Q-V provides functional flexibility beyond the fixed 500 PPR specification of the AMT303LD-V. When 500 PPR operation is required, the AMT313Q-V can be configured to this resolution, making it a direct functional replacement.

Frequently Asked Questions (FAQ)

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

A: Yes. Both encoders share identical mounting type, orientation, actuator compatibility, supply voltage, and termination style. The AMT313Q-V can be configured to match the 500 PPR output of the AMT303LD-V.

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

A: The AMT303LD-V has a fixed 500 PPR output, while the AMT313Q-V features programmable PPR selection. The AMT303LD-V is obsolete; the AMT313Q-V is actively manufactured.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V uses terminal pin termination without specified packaging detail. The AMT313Q-V is supplied in box packaging. Both use identical terminal pin termination style.

Q: Do both encoders meet current regulatory requirements?

A: Yes. Both are RoHS compliant and REACH unaffected. The AMT313Q-V carries ROHS3 certification, representing the current RoHS standard iteration.

Q: What is the moisture sensitivity rating for these encoders?

A: Both the AMT303LD-V and AMT313Q-V carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints for storage or handling.
