AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 250 pulses per revolution with commutation output in counter-clockwise direction and 20-pole right-angle orientation. This component is designed for chassis mount and motor applications with a 5V supply requirement and open center actuator (2mm–8mm range).

The AMT303-V is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for new designs or replacement applications where the original part is no longer in production.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-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 and Motors
• Orientation: Must be Right Angle
• Output Type: Must support Commutation output
• Pulses per Revolution: The AMT303-V specifies 250 PPR as a fixed value; substitute parts with programmable PPR capability can be configured to match this specification

The substitute parts AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active CUI Devices products in the AMT31 series with programmable pulse-per-revolution settings, allowing configuration to the 250 PPR requirement of the original design.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing long-term availability compared to the obsolete AMT303-V. Both substitute parts maintain full compliance with RoHS3 and REACH requirements, meeting modern regulatory standards.

The primary distinction between the two substitutes is termination style: AMT313Q-V uses terminal pins (matching the original AMT303-V), while AMT313S-V uses a connector interface. Selection between these two should be based on the existing system's connector or terminal pin requirements.

Both substitutes feature programmable pulses-per-revolution capability, which must be configured to 250 PPR to match the original specification. This programmability provides design flexibility for future applications while maintaining backward compatibility with existing 250 PPR designs.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be directly substituted for AMT303-V without modification?

A: Both parts share the same core electrical and mechanical parameters (5V supply, incremental encoder type, commutation output, right-angle orientation, chassis mount capability, and 2mm–8mm open center actuator). However, the AMT313 series features programmable PPR configuration. The 250 PPR specification must be programmed into the substitute part to match the original AMT303-V functionality.

Q: What is the difference between AMT313Q-V and AMT313S-V?

A: Both parts are functionally equivalent with identical electrical specifications and programmable PPR capability. The difference is termination style: AMT313Q-V provides terminal pins, while AMT313S-V provides a connector interface. Selection depends on your system's existing connector or terminal pin configuration.

Q: Why is the AMT303-V listed as obsolete?

A: The AMT303-V has been discontinued by CUI Devices. The AMT313 series represents the current active product line for this encoder category, offering enhanced programmability while maintaining compatibility with the core specifications of the AMT303-V.

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

A: The AMT303-V is RoHS Compliant. Both substitute parts (AMT313Q-V and AMT313S-V) are ROHS3 Compliant, representing a higher standard of environmental compliance. All three parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What packaging is available for the substitute parts?

A: Both AMT313Q-V and AMT313S-V are supplied in box packaging, suitable for standard component handling and storage.
