AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured with 192 pulses per revolution and 20-pole commutation output in a right-angle orientation. This encoder 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 compatibility and ensure continued availability for applications currently utilizing this encoder model.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMT303-V is determined by the following critical parameters:

• Encoder Type: Must be Incremental
• Output Type: Must support Commutation output
• 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
• Detent & Built-in Switch: Must match (No for both)

The substitute parts AMT313Q-V and AMT313S-V satisfy these core compatibility criteria. Both are active-status encoders from the AMT31 series with programmable pulses per revolution, allowing configuration to match the 192 PPR specification of the AMT303-V. Both maintain identical supply voltage, actuator type, mounting configuration, and orientation.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active-status alternatives to the obsolete AMT303-V. Selection between these two substitutes depends on termination requirements:

AMT313Q-V maintains terminal pin termination, matching the original AMT303-V configuration. This option minimizes integration changes for existing designs.

AMT313S-V uses connector termination, requiring interface modification but offering standardized connector-based integration for new or updated designs.

Both substitutes meet current RoHS3 and REACH compliance standards, exceeding the original RoHS Compliant specification of the AMT303-V. The programmable pulses per revolution feature of both substitutes allows configuration to the 192 PPR specification required by the original application.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 192 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution, allowing configuration to 192 PPR to match the original encoder specification.

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

A: The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination. All other electrical and mechanical parameters are identical.

Q: Are the substitute parts compatible with existing AMT303-V mounting locations?

A: Yes. Both AMT313Q-V and AMT313S-V share identical mounting type (Chassis Mount, Motors), orientation (Right Angle), and actuator specifications (2mm–8mm Open Center) with the AMT303-V.

Q: Do the substitute parts meet current compliance requirements?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards.

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

A: Product obsolescence is determined by the manufacturer. The active-status AMT313 series provides equivalent functionality with programmable configuration flexibility and current compliance certifications.
