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 counter-clockwise (CCW) orientation. This encoder features a right-angle mounting design with a 2mm to 8mm open center actuator and operates at 5V supply voltage. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications requiring incremental encoder functionality with similar electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on strict alignment with 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
• RoHS Compliance: RoHS3 or equivalent

The substitute parts AMT313Q-V and AMT313S-V maintain compatibility with these core electrical and mechanical specifications. Both alternatives feature programmable pulses per revolution capability, allowing configuration to match the original 800 PPR specification of the AMT303-V. Both substitutes are active products with current manufacturing status, addressing the obsolescence of the original part.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing support, providing direct 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 connection style. This option provides the closest form-factor compatibility for existing circuit designs.

• AMT313S-V: Features connector-based termination, offering an alternative connection method. This configuration may require circuit board redesign or adapter implementation depending on existing socket infrastructure.

Both substitutes support programmable pulses per revolution, enabling configuration to the original 800 PPR specification. Both maintain full compliance with RoHS3 and REACH requirements, ensuring regulatory alignment with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can AMT313Q-V and AMT313S-V be configured to match the 800 PPR output of the AMT303-V?

A: Yes. Both substitute parts feature programmable pulses per revolution capability, allowing configuration to 800 PPR to match the original specification.

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

Q: Are the substitute parts compatible with existing 5V supply circuits?

A: Yes. Both AMT313Q-V and AMT313S-V operate at 5V supply voltage, matching the original AMT303-V specification.

Q: Do the substitute parts maintain the same mounting orientation as the AMT303-V?

A: Yes. Both substitutes feature right-angle orientation with chassis mount capability for motor applications, identical to the original part.

Q: What compliance certifications apply to the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute should be selected for direct circuit board replacement?

A: AMT313Q-V is recommended for direct replacement applications due to matching terminal pin termination style with the original AMT303-V.
