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. The encoder 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
• Regulatory Compliance: RoHS and REACH status must be maintained or improved

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across all critical mechanical and electrical parameters. While the AMT313Q-V features programmable pulses per revolution (versus the fixed 1024 PPR of the AMT303LD-V), this represents a functional enhancement that does not compromise backward compatibility in applications requiring the 1024 PPR configuration.

Parameter Comparison

Engineering Selection Recommendations

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

Regulatory Compliance: The AMT313Q-V maintains RoHS compliance (ROHS3 Compliant) and REACH Unaffected status, meeting or exceeding the regulatory requirements of the original part.

Product Status: The AMT313Q-V is classified as Active, ensuring ongoing manufacturer support, availability, and supply chain continuity.

Mechanical and Electrical Compatibility: All critical parameters—supply voltage, actuator type, mounting configuration, orientation, and termination style—are identical between the two parts, ensuring direct mechanical and electrical compatibility in existing designs.

Functional Enhancement: The programmable pulses per revolution feature of the AMT313Q-V provides design flexibility while maintaining the ability to operate at the fixed 1024 PPR specification of the original part.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical mechanical mounting, electrical supply voltage, actuator type, orientation, and termination style. The AMT313Q-V's programmable PPR capability does not prevent operation at the 1024 PPR configuration required by the original design.

Q: What is the difference between fixed and programmable pulses per revolution?

A: The AMT303LD-V provides a fixed output of 1024 pulses per revolution. The AMT313Q-V allows the PPR setting to be configured, offering flexibility for different application requirements while maintaining the ability to operate at 1024 PPR.

Q: Are there any packaging differences between these parts?

A: The AMT303LD-V is packaged in standard format, while the AMT313Q-V is packaged in a Box. Both use identical terminal pin termination and are suitable for the same mounting applications.

Q: Does the AMT313Q-V meet current regulatory requirements?

A: Yes. The AMT313Q-V is ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards. The original AMT303LD-V was RoHS Compliant, and the substitute maintains or exceeds this compliance level.

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

A: Product obsolescence typically results from manufacturer discontinuation decisions. The AMT313Q-V represents the active alternative within the CUI Devices encoder product line, offering equivalent functionality with enhanced programmability.
