AMT303LD-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303LD-V is an incremental rotary encoder manufactured by CUI Devices, featuring 250 pulses per revolution with commutation output, CCW 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 carries an obsolete product status. 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

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

• Encoder Type: Must be Incremental
• Voltage Supply: Must be 5V
• Actuator Type: Must be 2mm ~ 8mm Open Center
• Mounting Type: Must support Chassis Mount, Motors
• Orientation: Must be Right Angle
• Termination Style: Must be Terminal Pins
• Output Configuration: Must support commutation output with line driver capability

The AMT313Q-V meets these core substitution criteria. While the AMT313Q-V features programmable pulses per revolution rather than fixed 250 PPR, this parameter can be configured to match the original specification, making it functionally equivalent for applications requiring 250 PPR operation.

Parameter Comparison

Engineering Selection Recommendations

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

Product Status: The AMT313Q-V maintains active product status with current manufacturing support, whereas the AMT303LD-V is obsolete. This ensures long-term availability and supply chain continuity.

Compliance & Certifications: Both parts maintain equivalent environmental compliance. The AMT313Q-V achieves ROHS3 Compliant status, representing an advancement over the original RoHS Compliant designation. Both parts are REACH Unaffected and carry identical ECCN and HTSUS classifications.

Functional Compatibility: The AMT313Q-V preserves all critical mechanical and electrical parameters: 5V supply voltage, right-angle orientation, chassis mount configuration, terminal pin termination, and open center actuator range. The programmable pulses per revolution feature allows configuration to the original 250 PPR specification.

Inventory Availability: The AMT313Q-V is available in higher stock quantities (1349 Pcs) compared to the limited remaining inventory of the obsolete AMT303LD-V (998 Pcs).

Frequently Asked Questions (FAQ)

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

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303LD-V across all mounting, orientation, and termination parameters. The programmable PPR feature must be configured to 250 PPR to match the original specification. No hardware modifications are required.

Q: What is the difference between fixed 250 PPR and programmable PPR?

A: The AMT303LD-V provides a fixed 250 PPR output. The AMT313Q-V allows PPR configuration through programming, enabling the same 250 PPR output when set accordingly. This flexibility provides additional functionality without compromising compatibility.

Q: Are there packaging differences between these parts?

A: The AMT303LD-V is supplied with standard packaging, while the AMT313Q-V is packaged in a Box configuration. Both maintain identical MSL ratings and handling requirements.

Q: Why is the AMT303LD-V obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The AMT313Q-V represents the active product line continuation with enhanced programmability while maintaining core functional parameters.

Q: Are both parts RoHS compliant?

A: Yes. The AMT303LD-V is RoHS Compliant, and the AMT313Q-V is ROHS3 Compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What supply voltage do these encoders require?

A: Both the AMT303LD-V and AMT313Q-V operate at 5V supply voltage. No voltage adjustment is necessary when substituting between these parts.
