AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1000 pulses per revolution with commutation output, CW polarity, and 2-pole line driver configuration. 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 qualifies as a substitute based on the following matching parameters:

• Manufacturer: CUI Devices (same manufacturer ensures design compatibility)
• Encoder Type: Incremental (functional equivalence)
• Output Type: Commutation (same output signal architecture)
• Voltage - Supply: 5V (identical electrical requirement)
• Actuator Type: 2mm ~ 8mm Open Center (mechanical compatibility)
• Mounting Type: Chassis Mount, Motors (same application context)
• Orientation: Right Angle (identical physical orientation)
• Termination Style: Terminal Pins (same connection method)
• RoHS Status: ROHS3 Compliant (meets or exceeds compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (equivalent environmental rating)

The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 1000 PPR. The AMT313Q-V is an active product with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

The AMT313Q-V is suitable as a substitute for the obsolete AMT303LD-V based on the following factors:

• Both components share identical electrical supply requirements (5V) and mechanical mounting specifications
• Both maintain equivalent environmental compliance ratings (MSL 1 - Unlimited)
• The AMT313Q-V holds active product status with current manufacturing availability, addressing the obsolescence of the original part
• ROHS3 compliance of the substitute meets or exceeds the RoHS Compliant status of the main part
• Both components are manufactured by CUI Devices, ensuring design consistency within the same product ecosystem

The programmable PPR capability of the AMT313Q-V provides additional flexibility compared to the fixed 1000 PPR specification of the AMT303LD-V. System integration must account for this functional difference during implementation.

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V shares all critical mechanical and electrical parameters with the AMT303LD-V, including mounting type, orientation, supply voltage, and termination style. The primary consideration is that the AMT313Q-V features programmable PPR configuration, whereas the AMT303LD-V is fixed at 1000 PPR. System firmware or configuration must be updated to set the AMT313Q-V to 1000 PPR operation if this specification is required.

Q: What is the significance of the programmable PPR feature in the AMT313Q-V?

A: The programmable pulses per revolution capability allows the AMT313Q-V to be configured for different resolution settings post-manufacture. This provides design flexibility but requires configuration during system integration. If 1000 PPR operation is required, the AMT313Q-V must be programmed accordingly.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V packaging is listed as standard, while the AMT313Q-V is supplied in Box packaging. Both use identical terminal pin termination and mounting specifications, so packaging differences do not affect mechanical or electrical compatibility.

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

A: Product obsolescence typically results from manufacturer discontinuation decisions. The AMT313Q-V, as an active CUI Devices product in the same encoder family, provides functional continuity for applications requiring incremental rotary encoding with commutation output.

Q: Are compliance certifications equivalent between the two parts?

A: Both parts maintain RoHS compliance and REACH Unaffected status. The AMT313Q-V carries ROHS3 certification, which represents a current compliance standard. Both components share identical MSL ratings (1 - Unlimited) and ECCN/HTSUS classifications.
