AMT303-V Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The AMT303-V is an incremental rotary encoder manufactured by CUI Devices, configured for 400 pulses per revolution with commutation output in counter-clockwise direction and 4-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 is required.

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 (required match)
• Voltage Supply: 5V (required match)
• Actuator Type: 2mm–8mm Open Center (required match)
• Mounting Type: Chassis Mount, Motors (required match)
• Orientation: Right Angle (required match)
• Output Type: Commutation (required match)
• Pulses per Revolution: 400 fixed or programmable to 400 (acceptable)

The substitute parts AMT313Q-V and AMT313S-V meet these core electrical and mechanical parameters. Both are active products from CUI Devices with programmable pulse-per-revolution capability, allowing configuration to the 400 PPR specification required by the AMT303-V application. The primary differences between substitutes relate to termination style and packaging format.

Parameter Comparison

Engineering Selection Recommendations

Both AMT313Q-V and AMT313S-V are active products with current manufacturing status, providing supply chain continuity compared to the obsolete AMT303-V. Both substitutes maintain full compliance with RoHS3 and REACH requirements, meeting modern regulatory standards.

AMT313Q-V retains terminal pin termination identical to the main part, minimizing integration changes in existing designs. This substitute is optimal for direct replacement in applications where the original terminal pin interface is already established.

AMT313S-V features connector-based termination, which differs from the main part's terminal pin configuration. This substitute is suitable for applications where connector-based termination is acceptable or preferred, offering potential advantages in modularity and serviceability.

Both substitutes employ programmable pulse-per-revolution configuration, requiring initialization to 400 PPR to match the original AMT303-V specification. This programmability provides flexibility for future design modifications without component substitution.

Frequently Asked Questions (FAQ)

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

A: Both substitutes meet the core electrical and mechanical parameters (5V supply, incremental encoder type, commutation output, 400 PPR capability, right-angle orientation, chassis mount configuration, and 2mm–8mm open center actuator). The primary difference is termination style: AMT313Q-V uses terminal pins (matching AMT303-V), while AMT313S-V uses a connector interface. Selection depends on your existing harness and interface requirements.

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

A: Both parts are functionally equivalent in electrical performance and mechanical form factor. The distinction is termination style: AMT313Q-V provides terminal pins for direct soldering or wire attachment, while AMT313S-V uses a connector interface. Choose based on your assembly and integration method.

Q: Do the substitute parts require configuration?

A: Yes. Both AMT313Q-V and AMT313S-V feature programmable pulse-per-revolution capability. To match the AMT303-V specification, these substitutes must be programmed to 400 PPR during integration or initialization.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both AMT313Q-V and AMT313S-V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the inventory status of these substitutes?

A: AMT313Q-V has 1349 pieces in stock, and AMT313S-V has 1045 pieces in stock, both available as new original components.
