AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 96 pulses per revolution with commutation output in counter-clockwise (CCW) orientation. This encoder features a right-angle mounting design with a 2mm to 8mm open center actuator and operates at 5V supply voltage. The product is classified as obsolete, necessitating identification of active alternative models that maintain functional and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on strict alignment with the following critical parameters:

• Encoder Type: Incremental (required match)
• Output Type: Commutation output capability (required match)
• Voltage - Supply: 5V operation (required match)
• Actuator Type: 2mm ~ 8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Manufacturer: CUI Devices (preferred continuity)

The substitute parts AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active products from CUI Devices with incremental encoder architecture, commutation output, 5V supply voltage, identical actuator specifications, and right-angle orientation. The key distinction between substitutes is the pulses per revolution configuration (programmable versus fixed 96 PPR) and termination style (terminal pins versus connector).

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply continuity advantages over the obsolete AMT303-V. Both substitutes maintain full compliance with RoHS3 and REACH requirements, meeting modern regulatory standards.

AMT313Q-V is recommended for applications requiring terminal pin termination, matching the original AMT303-V connection method. The programmable pulses per revolution feature provides flexibility for systems that may require resolution adjustment without component substitution.

AMT313S-V is recommended for applications where connector-based termination is acceptable or preferred. The connector interface may simplify integration in modular system designs while maintaining identical mechanical and electrical compatibility across all other parameters.

Selection between these two substitutes should be based on termination style requirements and system integration methodology rather than functional encoder performance, as both deliver equivalent incremental commutation output at 5V with identical mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be used interchangeably with AMT303-V?

A: Both substitutes are mechanically and electrically compatible with the AMT303-V in applications requiring incremental commutation output at 5V with right-angle orientation and 2mm to 8mm open center actuator. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface.

Q: What is the significance of programmable pulses per revolution in the substitute parts?

A: The AMT303-V is fixed at 96 PPR, while AMT313Q-V and AMT313S-V offer programmable resolution. This allows the substitute parts to be configured to 96 PPR to match the original specification, or adjusted to alternative resolutions if system requirements change.

Q: Are there compliance differences between the original and substitute parts?

A: The AMT303-V carries RoHS Compliant status, while both substitutes are ROHS3 Compliant, representing an updated compliance standard. Both maintain REACH Unaffected status. The substitutes meet current regulatory requirements for new designs and manufacturing.

Q: Which substitute should be selected for direct replacement in existing designs?

A: AMT313Q-V is the preferred direct replacement due to matching terminal pin termination style. No connector interface modifications are required for integration into existing PCB layouts or wiring harnesses designed for the AMT303-V.

Q: Does the connector termination of AMT313S-V affect electrical performance?

A: No. The connector termination of AMT313S-V is a mechanical interface difference only. Electrical performance, output characteristics, and signal integrity remain equivalent to AMT313Q-V and the original AMT303-V across all specified parameters.
