AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 1000 pulses per revolution with commutation output in counter-clockwise direction and 4-pole right-angle orientation. This component is classified as obsolete, necessitating identification of active substitute parts 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 the following critical parameters that determine functional and mechanical interchangeability:

• Encoder Type: Incremental
• Output Type: Commutation
• Voltage Supply: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• RoHS Compliance: RoHS3 Compliant

The substitute parts AMT313Q-V and AMT313S-V maintain these core parameters. Both are active products from CUI Devices with programmable pulses per revolution capability, allowing configuration to match the fixed 1000 PPR specification of the AMT303-V. The primary distinction between substitutes is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the AMT303-V, the following selection criteria apply:

AMT313Q-V is the primary substitute when terminal pin termination is required. This part maintains identical termination style to the AMT303-V and is an active product with ROHS3 compliance. Programmable pulses per revolution capability allows configuration to the 1000 PPR specification of the original part.

AMT313S-V is suitable for applications where connector termination is acceptable or preferred. This part provides the same electrical and mechanical compatibility as AMT313Q-V with the advantage of connector-based interface. ROHS3 compliance and active product status ensure long-term availability.

Both substitutes are manufactured by CUI Devices and comply with REACH and EAR99 export classifications, matching the regulatory profile of the obsolete AMT303-V.

Frequently Asked Questions (FAQ)

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

A: Both parts maintain the core electrical and mechanical parameters of the AMT303-V: incremental encoder type, commutation output, 5V supply, 2mm ~ 8mm open center actuator, chassis mount orientation, and right-angle configuration. The primary difference is termination style. AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses connector termination. Selection depends on the interface requirements of the application.

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

A: The AMT303-V has a fixed 1000 PPR specification. The substitute parts AMT313Q-V and AMT313S-V feature programmable PPR capability, allowing configuration to match the 1000 PPR requirement. This programmability provides flexibility for future applications without requiring different part numbers.

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

A: The AMT303-V is RoHS Compliant. Both substitute parts are ROHS3 Compliant, representing an updated compliance standard. All three parts are REACH Unaffected and classified as EAR99 for export purposes.

Q: Which substitute should be selected for new designs?

A: For new designs requiring terminal pin termination, select AMT313Q-V. For applications where connector termination is acceptable, AMT313S-V offers equivalent functionality. Both are active products with confirmed long-term availability.

Q: Does termination style affect electrical performance?

A: Termination style affects mechanical interface and assembly method but does not alter the electrical output characteristics. Selection should be based on the existing connector or terminal infrastructure of the application.
