AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, featuring 512 pulses per revolution with 8-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback. The AMT303-V is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMT303-V are identified based on the following critical parameters that must align for functional compatibility:

• Encoder Type: Incremental
• Output Type: Commutation
• Supply Voltage: 5V
• Actuator Type: 2mm ~ 8mm Open Center
• Mounting Type: Chassis Mount, Motors
• Orientation: Right Angle
• Detent: No
• Built-in Switch: No

The AMT313Q-V and AMT313S-V meet these core electrical and mechanical requirements. Both substitute parts feature programmable pulses per revolution, allowing configuration to match the 512 PPR specification of the original AMT303-V. The primary distinction between substitutes lies in termination style: the AMT313Q-V uses terminal pins (matching the original), while the AMT313S-V uses a connector interface.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the AMT303-V, the AMT313Q-V is the primary substitute due to matching termination style (terminal pins) and active product status. This part maintains direct compatibility with existing PCB layouts and wiring harnesses while providing programmable PPR configuration to achieve the 512 PPR specification of the original design.

The AMT313S-V serves as an alternative where connector-based termination is acceptable or preferred. This part offers the same electrical and mechanical compatibility with the added benefit of standardized connector interfacing, which may simplify assembly and field replacement procedures.

Both substitute parts carry ROHS3 compliance, exceeding the RoHS compliance of the obsolete AMT303-V, and are classified as active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the AMT313Q-V directly replace the AMT303-V without modifications?

A: The AMT313Q-V is mechanically and electrically compatible with the AMT303-V. Both use terminal pin termination, 5V supply, and identical mounting configurations. The programmable PPR feature of the AMT313Q-V must be configured to 512 PPR to match the original specification.

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

A: The AMT313Q-V uses terminal pins for connection, matching the original AMT303-V termination style. The AMT313S-V uses a connector interface. Selection depends on whether existing wiring and PCB layouts support connector-based termination.

Q: Are the substitute parts compatible with the same supply voltage?

A: Yes. Both the AMT313Q-V and AMT313S-V operate at 5V supply voltage, identical to the AMT303-V.

Q: Do the substitute parts support the same actuator range?

A: Yes. Both substitute parts support the 2mm ~ 8mm open center actuator type, matching the original AMT303-V specification.

Q: What compliance certifications apply to the substitute parts?

A: Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, with EAR99 export classification and matching HTSUS codes to the original part.
