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 6-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 design continuity and ensure component availability for new production runs, repairs, and system upgrades where this encoder specification remains functionally required.

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
• Supply Voltage: Must be 5V
• Actuator Type: Must be 2mm – 8mm Open Center
• Mounting Type: Must support Chassis Mount and Motors
• Orientation: Must be Right Angle
• Pulses per Revolution: The AMT303-V specifies 800 PPR as a fixed parameter. Substitute parts with programmable PPR capability satisfy this requirement, as 800 PPR can be configured within the programmable range.

The substitute parts AMT313Q-V and AMT313S-V meet all critical substitution criteria. Both are active-status incremental encoders with commutation output, 5V supply, matching actuator and mounting specifications, and right-angle orientation. The key distinction is termination style: AMT313Q-V uses terminal pins (matching the original), while AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

AMT313Q-V is the primary substitute for direct replacement of the AMT303-V. It maintains terminal pin termination, matching the original interface requirement. The part is active-status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Programmable PPR capability provides design flexibility while supporting the original 800 PPR specification.

AMT313S-V is an alternative substitute when connector-based termination is acceptable in the system design. This part offers identical electrical and mechanical compatibility with the exception of termination interface. Connector termination may simplify assembly in applications where modular connection is preferred.

Both substitutes are compliant with current RoHS3 standards and carry unlimited moisture sensitivity rating, meeting or exceeding the environmental specifications of the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy the core electrical and mechanical substitution criteria. The selection between them depends on termination interface requirements. AMT313Q-V uses terminal pins (direct replacement for pin-based connections), while AMT313S-V uses a connector interface (suitable for connector-based designs).

Q: What is the significance of programmable PPR in the substitute parts?

A: The AMT303-V specifies a fixed 800 PPR configuration. The substitute parts feature programmable PPR, allowing 800 PPR to be set during system initialization or configuration. This provides equivalent functional performance while offering design flexibility for future applications.

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

A: The AMT303-V carries RoHS Compliant status. Both substitutes meet ROHS3 Compliant standards, which represent a more current regulatory framework. All three parts maintain identical moisture sensitivity ratings (MSL 1, Unlimited).

Q: What is the impact of product status on part selection?

A: The AMT303-V is obsolete, indicating discontinued manufacturing and limited future availability. Both substitute parts are active-status, ensuring continued production, technical support, and long-term supply chain reliability.

Q: Are there packaging differences to consider?

A: The AMT303-V is supplied with standard packaging. AMT313Q-V and AMT313S-V are supplied in box packaging. Packaging differences do not affect functional performance or electrical characteristics.
