AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 400 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 compatibility and ensure continued availability for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Must be Incremental
• Output Type: Must support Commutation with line driver capability
• Pulses per Revolution: Fixed at 400 PPR or programmable to 400 PPR
• Voltage - Supply: 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

The AMT313Q-V qualifies as a substitute part because it maintains compatibility across all critical parameters. While the AMT313Q-V features programmable pulses per revolution (versus fixed 400 PPR on the AMT303LD-V), it can be configured to operate at 400 PPR, satisfying the functional requirement.

Parameter Comparison

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Product Status: The AMT303LD-V is obsolete, while the AMT313Q-V maintains active product status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both parts maintain full RoHS and REACH compliance. The AMT313Q-V achieves ROHS3 Compliant status, representing current regulatory standards. Both parts carry EAR99 ECCN classification and identical HTSUS codes, confirming equivalent trade classification.

Functional Compatibility: The AMT313Q-V's programmable pulses per revolution feature provides operational flexibility while maintaining the ability to function at the fixed 400 PPR specification of the original part. All mechanical, electrical, and interface parameters remain consistent.

Environmental Specifications: Both parts share identical MSL ratings (1 - Unlimited), confirming equivalent moisture sensitivity and storage requirements.
