AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 200 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 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

Substitute parts for the AMT303LD-V are identified based on the following critical parameters that determine functional compatibility:

• Encoder Type: Incremental
• Voltage - Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Termination Style: Terminal Pins
• Detent: No
• Built in Switch: No
• RoHS Status: RoHS Compliant or equivalent
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The AMT313Q-V qualifies as a substitute because it maintains all critical mechanical and electrical parameters. The primary difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 200 PPR. This difference does not prevent substitution in applications where 200 PPR operation is required, as the programmable encoder can be configured to this specification.

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V. Selection of the AMT313Q-V is supported by the following factors:

Product Status: The AMT313Q-V maintains active product status with CUI Devices, ensuring continued availability and supply chain reliability compared to the obsolete AMT303LD-V.

Compliance: Both parts maintain equivalent regulatory compliance. The AMT313Q-V achieves ROHS3 Compliant status, which supersedes the RoHS Compliant designation of the AMT303LD-V. Both parts maintain REACH Unaffected status and identical moisture sensitivity ratings.

Functional Compatibility: The AMT313Q-V preserves all critical mechanical and electrical parameters including 5V supply voltage, right-angle orientation, chassis mount configuration, and terminal pin termination. The programmable pulses per revolution feature of the AMT313Q-V provides operational flexibility while maintaining the ability to function at the fixed 200 PPR specification of the original part.

Frequently Asked Questions (FAQ)

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

A: Yes. The AMT313Q-V maintains identical mechanical mounting, electrical supply voltage, actuator type, and termination style. The programmable PPR feature does not prevent direct substitution when configured to 200 PPR operation.

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

A: The AMT303LD-V has a fixed 200 pulses per revolution specification, while the AMT313Q-V features programmable pulses per revolution. Both encoders share identical supply voltage, mounting configuration, orientation, and termination characteristics.

Q: Are there compliance differences between the two parts?

A: Both parts maintain RoHS compliance and REACH Unaffected status. The AMT313Q-V achieves ROHS3 Compliant designation, which represents a current compliance standard. Both parts carry identical moisture sensitivity ratings of MSL 1 (Unlimited).

Q: What is the packaging difference?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is supplied in box packaging. This difference does not affect functional compatibility or performance.

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

A: Product obsolescence is determined by the manufacturer. The active status of the AMT313Q-V provides a current alternative that maintains functional equivalence for applications requiring 200 PPR incremental encoder operation.
