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 4-pole commutation output in a right-angle orientation. This component is designed for chassis mount and motor applications requiring precise rotational feedback at 5V supply voltage.

The AMT303-V carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications currently utilizing this encoder.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Incremental (maintained across all substitutes)
• Output Type: Commutation configuration (maintained across all substitutes)
• Supply Voltage: 5V (maintained across all substitutes)
• Actuator Type: 2mm ~ 8mm Open Center (maintained across all substitutes)
• Mounting Type: Chassis Mount, Motors (maintained across all substitutes)
• Orientation: Right Angle (maintained across all substitutes)
• Termination Style: Terminal Pins or Connector (compatible interface options)

The AMT313Q-V and AMT313S-V are qualified substitutes because they maintain all critical electrical and mechanical parameters. The key distinction is that substitute parts feature programmable pulses per revolution, allowing configuration to match the original 1000 PPR specification, whereas the AMT303-V is fixed at 1000 PPR.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply chain continuity for applications currently using the obsolete AMT303-V.

AMT313Q-V: Maintains terminal pin termination style identical to the original AMT303-V, enabling direct mechanical and electrical interface compatibility with existing PCB layouts and connector designs.

AMT313S-V: Provides connector-based termination, requiring interface adapter consideration but offering enhanced modularity for applications where connector-based solutions are preferred.

Both substitutes carry ROHS3 compliance, exceeding the RoHS compliance level of the original part, and maintain identical electrical specifications and mechanical mounting parameters. The programmable pulses per revolution feature in both substitutes allows configuration to the original 1000 PPR specification through firmware or hardware programming.

Frequently Asked Questions (FAQ)

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

A: Both parts maintain identical electrical and mechanical parameters required for functional substitution. The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Selection depends on existing board-level integration requirements.

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

A: The AMT313Q-V and AMT313S-V feature programmable PPR, allowing configuration to match the original 1000 PPR specification. This provides flexibility for future design iterations while maintaining compatibility with the fixed 1000 PPR output of the AMT303-V.

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

A: The substitute parts carry ROHS3 compliance, which represents a more current regulatory standard than the RoHS compliance of the original AMT303-V. Both maintain identical moisture sensitivity levels and REACH unaffected status.

Q: Which substitute part should be selected for new designs?

A: Selection between AMT313Q-V and AMT313S-V depends on termination interface requirements. For direct replacement in existing designs using terminal pins, AMT313Q-V is appropriate. For new designs or applications requiring connector-based interfaces, AMT313S-V is suitable.

Q: Are supply voltage and mounting specifications identical across all three parts?

A: Yes. All three parts operate at 5V supply voltage, support 2mm ~ 8mm open center actuators, and are configured for chassis mount and motor applications in right-angle orientation.
