AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 800 pulses per revolution with commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications with an open center actuator range of 2mm to 8mm. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Manufacturer: CUI Devices

The AMT313Q-V and AMT313S-V meet these core compatibility criteria. Both are active CUI Devices incremental encoders with commutation output, 5V supply, matching actuator specifications, and right-angle orientation. The primary distinction between these substitutes is the pulses per revolution configuration and termination style. The AMT303-V specifies 800 PPR with terminal pins, while the AMT313 series offers programmable PPR capability with different termination options.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active product alternatives to the obsolete AMT303-V. Selection between these substitutes depends on termination requirements and system integration approach.

The AMT313Q-V maintains terminal pin termination identical to the AMT303-V, providing direct mechanical and electrical compatibility for applications requiring pin-based connections. This variant is suitable for direct board-level integration or wire harness termination.

The AMT313S-V employs connector-based termination, offering advantages in modularity and field replaceability. This configuration is appropriate for systems designed around connector-based encoder interfaces.

Both substitutes feature programmable pulses per revolution, enabling configuration to 800 PPR or alternative values as required by system specifications. Both are ROHS3 compliant, exceeding the RoHS compliance of the original part. Inventory availability is higher for both substitutes, supporting production continuity.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V or AMT313S-V be directly substituted for the AMT303-V?

A: Both parts meet the core compatibility criteria: incremental encoder type, commutation output, 5V supply, matching actuator and mounting specifications, and right-angle orientation. The AMT313Q-V is mechanically and electrically compatible with terminal pin termination. The AMT313S-V requires connector-based integration. Programmable PPR configuration allows both to operate at 800 PPR if required.

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

A: The primary difference is termination style. The AMT313Q-V uses terminal pins, matching the AMT303-V connection method. The AMT313S-V uses a connector interface. Both share identical encoder specifications, voltage supply, actuator type, mounting configuration, and orientation.

Q: Does the programmable PPR feature of the AMT313 series affect substitution compatibility?

A: The programmable PPR capability of the AMT313 series provides flexibility beyond the fixed 800 PPR of the AMT303-V. Systems requiring 800 PPR operation can configure the AMT313 series to this specification. Systems with different PPR requirements can utilize the programmable feature without requiring alternative encoder models.

Q: Are there packaging differences between these parts?

A: The AMT303-V is specified with dash packaging notation. The AMT313Q-V and AMT313S-V are supplied in box packaging. This reflects standard packaging for active versus obsolete product lines and does not affect functional compatibility.

Q: What compliance certifications apply to these substitutes?

A: All three parts are REACH Unaffected and classified as EAR99 for export control purposes. The AMT303-V carries RoHS Compliance certification. The AMT313Q-V and AMT313S-V carry ROHS3 Compliance certification, representing an enhanced compliance standard. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.
