AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 1024 pulses per revolution with commutation output, CW rotation, 2-pole configuration, and integrated line driver. 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 design continuity and ensure component availability for new production runs, repairs, and system upgrades.

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
• Manufacturer: CUI Devices (same manufacturer ensures design compatibility)

The AMT313Q-V qualifies as a substitute because it maintains compatibility across all mandatory mechanical and electrical parameters. The key difference is that the AMT313Q-V features programmable pulses per revolution, whereas the AMT303LD-V is fixed at 1024 PPR. This programmability provides additional flexibility while maintaining full mechanical and electrical interface compatibility.

Engineering Selection Recommendations

The AMT313Q-V is the qualified substitute for the obsolete AMT303LD-V based on the following factors:

Product Status: The AMT303LD-V is obsolete, making the active-status AMT313Q-V the appropriate replacement for ongoing production and support.

Compliance Alignment: Both parts maintain REACH Unaffected and EAR99 ECCN classifications. The AMT313Q-V achieves ROHS3 Compliant status, which exceeds the RoHS Compliant specification of the original part, ensuring enhanced environmental compliance.

Mechanical and Electrical Compatibility: All critical interface parameters—mounting type, orientation, termination style, actuator type, and supply voltage—are identical between the two parts, ensuring direct mechanical and electrical substitution without circuit redesign.

Functional Enhancement: The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility while maintaining the ability to configure the part to match the original 1024 PPR specification if required.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical mechanical mounting, electrical supply voltage (5V), actuator type, orientation, and termination style. The physical and electrical interfaces are fully compatible.

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

A: The AMT303LD-V has a fixed 1024 pulses per revolution output, while the AMT313Q-V features programmable pulses per revolution. The AMT313Q-V can be configured to operate at 1024 PPR to match the original specification.

Q: Are there any compliance or certification differences?

A: Both parts are REACH Unaffected and classified as EAR99. The AMT313Q-V carries ROHS3 Compliant certification, which is a higher environmental standard than the RoHS Compliant rating of the AMT303LD-V.

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

A: The AMT303LD-V has reached end-of-life status. CUI Devices has transitioned to the AMT313Q-V as the active product line for this encoder category.

Q: What packaging is available for the substitute part?

A: The AMT313Q-V is supplied in Box packaging.

Q: Are both parts available in stock?

A: The AMT303LD-V has 1067 pieces in stock as new original inventory. The AMT313Q-V has 1349 pieces in stock as new original inventory.
