AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 96 pulses per revolution with 8-pole 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

Substitution eligibility for the AMT303LD-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must be Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Detent: Must be No
• Built-in Switch: Must be No

The AMT313Q-V qualifies as a substitute part because it matches all mandatory parameters. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 96 PPR of the AMT303LD-V), this represents an enhancement in functionality rather than a limitation, as the programmable output can be configured to match the original 96 PPR specification when required.

Engineering Selection Recommendations

The AMT313Q-V is the identified substitute for the obsolete AMT303LD-V based on matching all critical electrical and mechanical parameters. The substitute part offers the following advantages:

• Active Product Status: The AMT313Q-V is currently in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Compliance: The AMT313Q-V meets ROHS3 Compliant standards, representing a higher level of environmental compliance compared to the original RoHS Compliant designation.
• Regulatory Alignment: Both parts maintain REACH Unaffected status and EAR99 ECCN classification, ensuring consistent regulatory positioning.
• Programmable Configuration: The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility while maintaining the ability to match the original 96 PPR output when configured accordingly.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303LD-V without modifications?

A: The AMT313Q-V matches all mandatory mechanical and electrical parameters of the AMT303LD-V. The programmable pulses per revolution feature requires configuration to match the original 96 PPR specification. Consult the AMT313Q-V datasheet for programming procedures specific to your application.

Q: What is the difference between fixed 96 PPR and programmable PPR?

A: The AMT303LD-V provides a fixed output of 96 pulses per revolution. The AMT313Q-V allows the pulses per revolution to be programmed to a specific value, including 96 PPR, providing greater flexibility for different system requirements.

Q: Are the packaging formats compatible?

A: The AMT303LD-V uses terminal pin termination in standard packaging. The AMT313Q-V is supplied in box packaging. Both parts use identical terminal pin termination style, ensuring mechanical and electrical compatibility in the application circuit.

Q: Why is the original part obsolete?

A: The AMT303LD-V is classified as obsolete, indicating it is no longer manufactured. The AMT313Q-V represents the active product line continuation from CUI Devices for this encoder category.

Q: Are there compliance differences between the two parts?

A: Both parts maintain REACH Unaffected status. The AMT313Q-V meets ROHS3 Compliant standards, while the AMT303LD-V meets RoHS Compliant standards. Both are suitable for applications requiring environmental compliance.
